net: systemport: TX/NAPI improvements
This patch series builds up on Doug's latest changes done in BCMGENET to reduce
the number of spurious interrupts in NAPI, simplify pointer arithmetic and
finally tracking of per TX ring statistics to be SMP friendly.

Do something similar to commit d5810ca3252a ("net: bcmgenet: clear
status to reduce spurious interrupts") and clear interrupts right before
servicing them. This reduces the number of interrupts by 10K
interrupts/sec for a TX TCP session 1Gbits/sec.

bcm_sysport_tx_reclaim_one() is currently summing TX bytes/packets in a
way that is not SMP friendly, mutliples CPUs could run
bcm_sysport_tx_reclaim_one() independently and still update
stats->tx_bytes and stats->tx_packets, cloberring the other CPUs
statistics.
Fix this by tracking per TX rings the number of bytes, packets,
dropped and errors statistics, and provide a bcm_sysport_get_nstats()
function which aggregates everything and returns a consistent output.

net: phy: Allow splitting MDIO bus/device support
This patch series allows building support for MDIO bus controllers which
are sometimes usable and necessary in cases where there are no Ethernet PHYs.
Changes in v3:
- corrected of_mdio compile guards for prototypes vs. stubs
- added a missing OF_MDIO dependency for MDIO_BCM_UNIMAC
- fixed Kbuild bot reported errors against mdio-bitbang
Changes in v2:
- implement Russell's feedback
- solve the circular dependency in the CONFIG_MDIO_DEVICE + CONFIG_PHYLIB case

Introduce a new configuration symbol: MDIO_DEVICE which allows building
the MDIO devices and bus code, without pulling in the entire Ethernet
PHY library and devices code.
PHYLIB nows select MDIO_DEVICE and the relevant Makefile files are
updated to reflect that.
When MDIO_DEVICE (MDIO bus/device only) is selected, but not PHYLIB, we
have mdio-bus.ko as a loadable module, and it does not have a
module_exit() function because the safety of removing a bus class is
unclear.
When both MDIO_DEVICE and PHYLIB are enabled, we need to assemble
everything into a common loadable module: libphy.ko because of nasty
circular dependencies between phy.c, phy_device.c and mdio_bus.c which
are really tough to untangle.

filter_list cannot be ever changed, being NULL all the time.
Reason is this check in tc_ctl_tfilter:

Two different set_mac functions exists but stmmac_dwmac4_set_mac() is
only used for enabling and never for disabling.
So on dwmac4, the MAC RX/TX is never disabled.
This patch add a generic function pointer set_mac() to stmmac_ops and
replace all call to stmmac_set_mac/stmmac_dwmac4_set_mac by a call to
this pointer.
Since dwmac4_ops is const, set_mac cannot be modified after, and so dwmac4_ops
is duplioacted like dwmac4_dma_ops.

net: bridge: allow user-space to add ext learned entries
This set adds the ability to add externally learned entries from
user-space. For symmetry and proper function we need to allow SW entries
to take over HW learned ones (similar to how HW can take over SW entries
currently) which is needed for our use case (evpn) where we have pure SW
ports and HW ports mixed in a single bridge. This does not play well with
switchdev devices currently because there's no feedback when the entry is
taken over, but this case has never worked anyway and feedback can be
easily added when needed.
Patch 02 simply allows to use NTF_EXT_LEARNED from user-space, we already
have Quagga patches that make use of this functionality.

The NTF_EXT_LEARNED flag was added for switchdev and externally learned
entries, but it can also be used for entries learned via a software
in user-space which requires dynamic entries that do not expire.
One such case that we have is with quagga and evpn which need dynamic
entries but also require to age them themselves.

Replace a complex if->continue->else->break construction in
i40e_next_filter. We can simply use hlist_for_each_entry_continue
instead. This drops a lot of confusing code. The resulting code is much
easier to understand the intention, and follows the more normal pattern
for using hlist loops. We could have also used a break with a "return
next" at the end of the function, instead of return NULL, but the
current implementation is explicitly clear that when you reach the end
of the loop you get a NULL value. The alternative construction is less
clear since the reader would have to know that next is NULL at the end
of the loop.

Add support for flexible payloads passed via ethtool user-def field.
This support is somewhat limited due to hardware design. The input set
can only be programmed once per filter type, and the flexible offset is
part of this filter input set. This means that the user cannot program
both a regular and a flexible filter at the same time for a given flow
type. Additionally, the user may not program two flexible filters of the
same flow type with different offsets, although they are allowed to
configure different values at that offset location.
We support a single flexible word (2byte) value per protocol type, and
we handle the FLX_PIT register using a list of flexible entries so that
each flow type may be configured separately.
Due to hardware implementation, the flexible data is offset from the
start of the packet payload, and thus may not be in part of the header
data. For this reason, the offset provided by the user defined data is
interpreted as a byte offset from the start of the matching payload.
Previous implementations have tried to represent the offset as from the
start of the frame, but this is not feasible because header sizes may
change due to options.

Add code to parse the user-def field into a data structure format. This
code is intended to allow future extensions of the user-def field by
keeping all code that actually reads and writes the field into a single
location. This ensures that we do not litter the driver with references
to the user-def field and minimizes the amount of bitwise operations we
need to do on the data.
Add code which parses the lower 32bits into a flexible word and its
offset. This will be used in a future patch to enable flexible filters
which can match on some arbitrary data in the packet payload. For now,
we just return -EOPNOTSUPP when this is used.
Add code to fill in the user-def field when reporting the filter back,
even though we don't actually implement any user-def fields yet.
Additionally, ensure that we mask the extended FLOW_EXT bit from the
flow_type now that we will be accepting filters which have the FLOW_EXT
bit set (and thus make use of the user-def field).

Do not use the user-def field for determining the VF target. Instead,
similar to ixgbe, partition the ring_cookie value into 8bits of VF
index, along with 32bits of queue number. This is better than using the
user-def field, because it leaves the field open for extension in
a future patch which will enable flexible data. Also, this matches with
convention used by ixgbe and other drivers.

Add support to detect when we can update the input set for each flow
type.
Because the hardware only supports a single input set for all flows of
that matching type, the driver shall only allow the input set to change
if there are no other configured filters for that flow type.
Thus, the first filter added for each flow type is allowed to change the
input set, and all future filters must match the same input set. Display
a diagnostic message whenever the filter input set changes, and
a warning whenever a filter cannot be accepted because it does not match
the configured input set.

Ensure that the default input set is correctly reprogrammed when
cleaning up after disabling flow director support. This ensures that the
programmed value will be in a clean state.
Although we do not yet have support for SCTPv4 filters, a future patch
will add support for this protocol, so we will correctly restore the
SCTPv4 input set here as well. Note that strictly speaking the default
hardware value for SCTP includes matching the verification tag. However,
the ethtool API does not have support for specifying this value, so
there is no reason to keep the verification field enabled.
This patch is the next step on the way to enabling partial tuple filters
which will be implemented in a following patch.

Do not assume that hardware has been programmed with the default mask,
but instead read the input set registers to determine what is currently
programmed. This ensures that all programmed filters match exactly how
the hardware will interpret them, avoiding confusion regarding filter
behavior.
This sets the initial ground-work for allowing custom input sets where
some fields are disabled. A future patch will fully implement this
feature.
Instead of using bitwise negation, we'll just explicitly check for the
correct value. The use of htonl and htons are used to silence sparse
warnings. The compiler should be able to handle the constant value and
avoid actually performing a byteswap.

The current implementation of .set_rxnfc does not properly read the mask
field for filter entries. This results in incorrect driver behavior, as
we do not reject filters which have masks set to ignore some fields. The
current implementation simply assumes that every part of the tuple or
"input set" is specified. This results in filters not behaving as
expected, and not working correctly.
As a first step in supporting some partial filters, add code which
checks the mask fields and rejects any filters which do not have an
acceptable mask. For now, we just assume that all fields must be set.
This will get the driver one step towards allowing some partial filters.
At a minimum, the ethtool commands which previously installed filters
that would not function will now return a non-zero exit code indicating
failure instead.
We should now be meeting the minimum requirements of the .set_rxnfc API,
by ensuring that all filters we program have a valid mask value for each
field.
Finally, add code to report the mask correctly so that the ethtool
command properly reports the mask to the user.
Note that the typecast to (__be16) when checking source and destination
port masks is required because the ~ bitwise negation operator does not
correctly handle variables other than integer size.

Change since V7:
* change the user namespace of uid helper function to sock_net(sk)->user_ns
Change since V6:
* change the user namespace of uid helper function back to init_user_ns
since in some situation, for example, pinned bpf object, the current
user namespace is not always applicable.
Change since V5:
* Delete unnecessary blank lines in sample program.
* Refine the variable orders in get_uid helper function.
Change since V4:
* Using current user namespace to get uid instead of using init_ns.
* Add compiling setup of example program in to Makefile.
* Change the name style of the example program binaries.
Change since V3:
* Fixed some typos and incorrect comments in sample program
* replaced raw insns with BPF_STX_XADD and add it to libbpf.h
* Use a temp dir as mount point instead and added a check for
the user input string.
* Make the get uid helper function returns the user namespace uid
instead of kuid.
* Return a overflowuid instead of 0 when no uid information is found.
Change since V2:
* Add a sample program to demostrate the usage of the helper function.
* Moved the helper function proto invoking place.
* Add function header into tools/include
* Apply sk_to_full_sk() before getting uid.
Change since V1:
* Removed the unnecessary declarations and export command
* resolved conflict with master branch.
* Examine if the socket is a full socket before getting the uid.

Patch #4 removes some unnecessary logging, allowing cleaner forward

If a new mangement firmware would work with an older driver,

log such messages at default verbosity; That would only serve to confuse

The management firmware is running on a Big Endian processor,
and when running on LE platform HW is configured to swap access
to memory shared between management firmware and driver on
32-bit granulariy.
As a result, for matters of simplicity most of the APIs between
driver and management firmware are based on 32-bit variables.
MAC settings are one exception, as driver needs to fill a byte
array when indicating to management firmware that primary MAC
has changed.
Due to the swap, driver must make sure that the mac that was
provided in byte-order would be translated into native order,
otherwise after the swap the management firmware would read
it swapped.

Current interface assumes the caller always passes such a union -

in case caller accidentally passes a smaller member instead of union].
Change implementation so that caller could pass a pointer to any

Interaction of driver -> management firmware is based
on a one-pending mailbox [per interface], and various
mailbox commands need to be synchronized.
Current scheme is messy, and there's a difficulty extending
it as it deals differently with various commands as well as
making assumption on the required behavior for load/unload
requests.
Drop the current scheme into a completion-list-based approach;
Each flow would try sending the command when possible,
allowing one flow to complete another flow's completion and
relieve the mailbox before sending its own command.

Pull btrfs fixes from Chris Mason:
"Zygo tracked down a very old bug with inline compressed extents.
I didn't tag this one for stable because I want to do individual
tested backports. It's a little tricky and I'd rather do some extra
testing on it along the way"
* 'for-linus-4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs:
btrfs: add missing memset while reading compressed inline extents
Btrfs: fix regression in lock_delalloc_pages
btrfs: remove btrfs_err_str function from uapi/linux/btrfs.h

The ECC bit positions that describe whether the ECC interrupt is for
Tx, Rx or descriptor memory and whether the it is a single correctable
or double detected error were defined in incorrectly (reversed order).
Fix the bit position definitions for these settings so that the proper
ECC handling is performed.
