local_cork is used to decide if it should uncork asoc outq after processing
some cmds, and it is set when replying or sending msgs. local_cork should
always have the same value with current asoc q->cork in some way.
The thing is when changing to a new asoc by cmd SET_ASOC, local_cork may
not be consistent with the current asoc any more. The cmd seqs can be:
SCTP_CMD_UPDATE_ASSOC (asoc)
SCTP_CMD_REPLY (asoc)
SCTP_CMD_SET_ASOC (new_asoc)
SCTP_CMD_DELETE_TCB (new_asoc)
SCTP_CMD_SET_ASOC (asoc)
SCTP_CMD_REPLY (asoc)
The 1st REPLY makes OLD asoc q->cork and local_cork both are 1, and the cmd
DELETE_TCB clears NEW asoc q->cork and local_cork. After asoc goes back to
OLD asoc, q->cork is still 1 while local_cork is 0. The 2nd REPLY will not
set local_cork because q->cork is already set and it can't be uncorked and
sent out because of this.
To keep local_cork consistent with the current asoc q->cork, this patch is
to uncork the old asoc if local_cork is set before changing to the new one.
Note that the above cmd seqs will be used in the next patch when updating
asoc and handling errors in it.

Now dccp_ipv4 works as a kernel module. During loading this module, if
one dccp packet is being recieved after inet_add_protocol but before
register_pernet_subsys in which v4_ctl_sk is initialized, a null pointer
dereference may be triggered because of init_net.dccp.v4_ctl_sk is 0x0.
Jianlin found this issue when the following call trace occurred:

net-next: mediatek: various performance improvements
During development we mainly ran testing using iperf doing 1500 byte
tcp frames. It was pointed out recently, that the driver does not perform
very well when using 512 byte udp frames. The biggest problem was that
RPS was not working as no rx queue was being set. fixing this more than
doubled the throughput. Additionally the IRQ mask register is now locked
independently for RX and TX. RX IRQ aggregation is also added. With all
these patches applied we can almost triple the throughput.
While at it we also add PHY status change reporting for GMACs connecting
directly to a PHY.

The get_rps_cpu() function will not do any RPS on the data flow when no

Originally the driver only utilised the new QDMA engine. The current code
still assumes this is the case when locking the IRQ mask register. Since
RX now runs on the old style PDMA engine we can add a second lock. This
patch reduces the IRQ latency as the TX and RX path no longer need to wait
on each other under heavy load.

The PDMA engine used for RX allows IRQ aggregation. The patch sets up the

reduces the load on the core handling to a quarter thus reducing IRQ

====================
vxlan: cleanup and IPv6 link-local support
Running VXLANs over IPv6 link-local addresses allows to use them as a
drop-in replacement for VLANs, avoiding to allocate additional outer IP
addresses to run the VXLAN over.
Since v1, I have added a lot more consistency checks to the address
configuration, making sure address families and scopes match. To simplify
the implementation, I also did some general refactoring of the
configuration handling in the new first patch of the series.
The second patch is more cleanup; is slightly touches OVS code, so that
list is in CC this time, too.
As in v1, the last two patches actually make VXLAN over IPv6 link-local
work, and allow multiple VXLANs with the same VNI and port, as long as
link-local addresses on different interfaces are used. As suggested, I now
store in the flags field if the VXLAN uses link-local addresses or not.
v3 removes log messages as suggested by Roopa Prabhu (as it is very unusual
for errors in netlink requests to be printed to the kernel log.) The commit
message of patch 5 has been extended to add a note about IPv4.
====================

As link-local addresses are only valid for a single interface, we can allow
to use the same VNI for multiple independent VXLANs, as long as the used
interfaces are distinct. This way, VXLANs can always be used as a drop-in
replacement for VLANs with greater ID space.
This also extends VNI lookup to respect the ifindex when link-local IPv6
addresses are used, so using the same VNI on multiple interfaces can
actually work.

If VXLAN is run over link-local IPv6 addresses, it is necessary to store
the ifindex in the FDB entries. Otherwise, the used interface is undefined
and unicast communication will most likely fail.
Support for link-local IPv4 addresses should be possible as well, but as
the semantics aren't as well defined as for IPv6, and there doesn't seem to
be much interest in having the support, it's not implemented for now.

The vxlan_dev_configure function was mixing validation and application of
the vxlan configuration; this could easily lead to bugs with the changelink
operation, as it was hard to see if the function wcould return an error
after parts of the configuration had already been applied.
This commit splits validation and application out of vxlan_dev_configure as
separate functions to make it clearer where error returns are allowed and
where the vxlan_dev or net_device may be configured. Log messages in these
functions are removed, as it is generally unexpected to find error output
for netlink requests in the kernel log. Userspace should be able to handle
errors based on the error codes returned via netlink just fine.
In addition, some validation and initialization is moved to vxlan_validate
and vxlan_setup respectively to improve grouping of similar settings.
Finally, this also fixes two actual bugs:
* if set, conf->mtu would overwrite dev->mtu in each changelink operation,
reverting other changes of dev->mtu
* the "if (!conf->dst_port)" branch would never be run, as conf->dst_port
was set in vxlan_setup before. This caused VXLAN-GPE to use the same
default port as other VXLAN sockets instead of the intended IANA-assigned
4790.

Some Marvell chips have an Ingress Rate Limit unit. But the command
values slightly differs between models: 88E6352 use 3-bit for operations
while 88E6390 use different 2-bit operations.
This commit kills the IRL flags in favor of a new operation implementing
the "Init all resources to the initial state" operation.
This fixes the operation of 88E6390 family where 0x1000 means Read the
selected resource 0, register 0 on port 16, instead of init all.
A mv88e6xxx_irl_setup helper is added to wrap the operation call.

The EPHY control part of the EMAC syscon register has a bit called
CLK_SEL. On the datasheet it says that if it's 0 the EPHY clock is 25MHz
and if it's 1 the clock is 24MHz.
However, according to the datasheets, no Allwinner SoC with EPHY has any
extra xtal input pins for the EPHY, and the system xtal is 24MHz.
That means the EPHY is not possible to get a 25MHz xtal input, and thus
the frequency can only be 24MHz.
It doesn't matter on H3 as the default value of H3 is 24MHz, however on
V3s the default value is wrongly set to 25MHz, which prevented the EPHY
from working properly.
Force the EPHY clock frequency to 24MHz.

Add the beginnings of a testsuite for tc functionality in the kernel.
These are a series of unit tests that use the tc executable and verify
the success of those commands by checking both the exit codes and the
output from tc's 'show' operation.
To run the tests:
# cd tools/testing/selftests/tc-testing
# sudo ./tdc.py
You can specify the tc executable to use with the -p argument on the command
line or editing the 'TC' variable in tdc_config.py. Refer to the README for
full details on how to run.
The initial complement of test cases are limited mostly to tc actions. Test

agnostic to the variant of the RDMA protocol used. These patches also
touch qedr [basically to align it with the renaming, nothing more].
- Patch #7 replaces the current SPQ async mechanism into serving
registered callbacks [before adding iWARP which would add another client
in need of this sort of functionallity].
The non-infrastrucutre changes:
- Patches #2, #3 contain DCB-related changes to better align RDMA with
configured DCB.
- Patch #6 contains a minor [mostly theoretical fix] to release flow.
Changes from previous versions
------------------------------
- V4: This is actually a repost of V3 due to some confusion regarding
the sent cover-letter
- V3: Add commit log message in #4 indicating change in header inclusion
- V2: Add several inclusion into qede_rdma.h to have proper declarations
of all variable types used in it

Whenever firmware indicates that there's an async indication it needs
to handle, there's a switch-case where the right functionality is called
based on function's personality and information.
Before iWARP is added [as yet another client], switch over the SPQ into
a callback-registered mechanism, allowing registration of the relevant
event-processing logic based on the function's personality. This allows
us to tidy the code by removing protocol-specifics from a common file.

Once we have iWARP support, the qede portion of the qedr<->qede would
serve all the RDMA protocols - so rename the file to be appropriate
to its function.
While we're at it, we're also moving a couple of inclusions to it into
.h files and adding includes to make sure it contains all type
definitions it requires.

iWARP would require the chains to allocate/free their PBL memory
independently, so add the infrastructure to provide it externally.
