Always updating port state in place by overriding values in exiting
pf->eth_tbl makes things easier to manage and allows us to have a
common helper for both full and per-port refresh.

Encapsulate port information into struct nfp_port. nfp_port will
soon be extended to contain devlink_port information. It also makes
it easier to reuse port-related code between vNICs and representors.

We only support core NIC apps which have vNICs for each physical port/
split and no representors right now. Enforce that either each vNIC has
a NSP eth_table entry or if NSP port table is not available none do.
One scenario this will prevent from happening is user force-loading
wrong firmware file if FW app requires different firmwares per media
config.
While at it move some code to nfp_net_pf_alloc_vnic() to make it
counter-match nfp_net_pf_free_vnic() better.

Introduce a concept of an application. For now it's just grouping
pointers and serving as a layer of indirection. It will help us
weaken the dependency on nfp_net in ethtool code. Later series
will flesh out support for different apps in the driver.

vNIC is a PCIe-side abstraction NFP firmwares supported by this
driver use. It was initially meant to represent a device port
and therefore a netdev but today should be thought of as a way
of grouping descriptor rings and associated state. Advanced apps
will have vNICs without netdevs and ports without a vNIC (using
representors instead).
Make sure code refers to vNICs as vNICs and not ports or netdevs.
No functional changes.

struct nfp_net represents a vNIC, we will be moving away from the
requirement for every vNIC to have a netdev associated with it.
Remove "netdev" from some function names and prefer passing
struct nfp_net pointer as argument instead of struct net_device *.

Current bridge code incorrectly handles starting/stopping of hello and
hold timers during STP enable/disable.
1. Timers are stopped in br_stp_start() during NO_STP->USER_STP
transition. The timers are already stopped in NO_STP state so
this is confusing no-op.
2. During USER_STP->NO_STP transition the timers are started. This
does not make sense and is confusion because the timer should not be
active in NO_STP state.

for such packets by atomically updating struct net_device`rx_dropped and

====================
Extend socket timestamping API
Changes v5->v6:
- fixed skb_is_swtx_tstamp() when OPT_TX_SWHW is disabled and improved
its description
- improved OPT_PKTINFO documentation
- improved scm_timestamping documentation
Changes v4->v5:
- fixed initialization of reserved fields in struct scm_ts_pktinfo
Changes v3->v4:
- added reserved fields to struct scm_ts_pktinfo
- replaced patch fixing false SW timestamps with a documentation fix
- updated OPT_TX_SWHW patch to handle false SW timestamps
Changes v2->v3:
- modified struct scm_ts_pktinfo to use fixed-width integer types
- added WARN_ON_ONCE for missing RCU lock in dev_get_by_napi_id()
- modified dev_get_by_napi_id() to not return dev in unexpected branch
- modified recv to return SCM_TIMESTAMPING_PKTINFO even if the interface
index is unknown
Changes v1->v2:
- added separate patch for new NAPI functions
- split code from __sock_recv_timestamp() for better readability
- fixed RCU locking
- fixed compiler warning (missing case in switch in first patch)
- inline sw_tx_timestamp() in its only user
Changes RFC->v1:
- reworked SOF_TIMESTAMPING_OPT_PKTINFO patch to not add new fields to
skb shared info (net device is now looked up by napi_id), not require
any changes in drivers, and restrict the cmsg to incoming packets
- renamed SOF_TIMESTAMPING_OPT_MULTIMSG to SOF_TIMESTAMPING_OPT_TX_SWHW
and fixed its description
- moved struct scm_ts_pktinfo from errqueue.h to net_tstamp.h as it
can't be received from the error queue anymore
- improved commit descriptions and removed incorrect comment
This patchset adds new options to the timestamping API that will be
useful for NTP implementations and possibly other applications.
The first patch specifies a timestamp filter for NTP packets. The second
patch updates drivers that can timestamp all packets, or need to list
the filter as unsupported. There is no attempt to add the support to the
phyter driver.
The third patch adds two helper functions working with NAPI ID, which is
needed by the next patch. The fourth patch adds a new option to get a
new control message with the L2 length and interface index for incoming
packets with hardware timestamps.
The fifth patch fixes documentation on number of non-zero fields in
scm_timestamping and warns about false software timestamps when
SO_TIMESTAMP(NS) is combined with SCM_TIMESTAMPING.
The sixth patch adds a new option to request both software and hardware
timestamps for outgoing packets. The seventh patch updates drivers that
assumed software timestamping cannot be used together with hardware
timestamping.
The patches have been tested on x86_64 machines with igb and e1000e
drivers.

Some drivers were calling the skb_tx_timestamp() function only when
a hardware timestamp was not requested. Now that applications can use
the SOF_TIMESTAMPING_OPT_TX_SWHW option to request both software and
hardware timestamps, the drivers need to be modified to unconditionally
call skb_tx_timestamp().

Add SOF_TIMESTAMPING_OPT_TX_SWHW option to allow an outgoing packet to
be looped to the socket's error queue with a software timestamp even
when a hardware transmit timestamp is expected to be provided by the
driver.
Applications using this option will receive two separate messages from
the error queue, one with a software timestamp and the other with a
hardware timestamp. As the hardware timestamp is saved to the shared skb
info, which may happen before the first message with software timestamp
is received by the application, the hardware timestamp is copied to the
SCM_TIMESTAMPING control message only when the skb has no software
timestamp or it is an incoming packet.
While changing sw_tx_timestamp(), inline it in skb_tx_timestamp() as
there are no other users.

when both software and hardware RX timestamping is enabled, or when the

Add SOF_TIMESTAMPING_OPT_PKTINFO option to request a new control message
for incoming packets with hardware timestamps. It contains the index of
the real interface which received the packet and the length of the
packet at layer 2.
The index is useful with bonding, bridges and other interfaces, where
IP_PKTINFO doesn't allow applications to determine which PHC made the
timestamp. With the L2 length (and link speed) it is possible to
transpose preamble timestamps to trailer timestamps, which are used in
the NTP protocol.
While this information could be provided by two new socket options
independently from timestamping, it doesn't look like they would be very
useful. With this option any performance impact is limited to hardware
timestamping.
Use dev_get_by_napi_id() to get the device and its index. On kernels
with disabled CONFIG_NET_RX_BUSY_POLL or drivers not using NAPI, a zero
index will be returned in the control message.

Since commit b68581778cd0 ("net: Make skb->skb_iif always track
skb->dev") skbs don't have the original index of the interface which
received the packet. This information is now needed for a new control
message related to hardware timestamping.
Instead of adding a new field to skb, we can find the device by the NAPI
ID if it is available, i.e. CONFIG_NET_RX_BUSY_POLL is enabled and the
driver is using NAPI. Add dev_get_by_napi_id() and also skb_napi_id() to
hide the CONFIG_NET_RX_BUSY_POLL ifdef.

Current largesend and checksum offload feature in ibmveth driver,
- Source VM sends the TCP packets with ip_summed field set as
CHECKSUM_PARTIAL and TCP pseudo header checksum is placed in
checksum field
- CHECKSUM_PARTIAL flag in SKB will enable ibmveth driver to mark
"no checksum" and "checksum good" bits in transmit buffer descriptor
before the packet is delivered to pseries PowerVM Hypervisor
- If ibmveth has largesend capability enabled, transmit buffer descriptors
are market accordingly before packet is delivered to Hypervisor
(along with mss value for packets with length > MSS)
- Destination VM's ibmveth driver receives the packet with "checksum good"
bit set and so, SKB's ip_summed field is set with CHECKSUM_UNNECESSARY
- If "largesend" bit was on, mss value is copied from receive descriptor
into SKB's gso_size and other flags are appropriately set for
packets > MSS size
- The packet is now successfully delivered up the stack in destination VM
The offloads described above works fine for TCP communication among VMs in
the same pseries server ( VM A <=> PowerVM Hypervisor <=> VM B )
We are now enabling support for OVS in pseries PowerVM environment. One of
our requirements is to have ibmveth driver configured in "Trunk" mode, when
they are used with OVS. This is because, PowerVM Hypervisor will no more
bridge the packets between VMs, instead the packets are delivered to
IO Server which hosts OVS to bridge them between VMs or to external
networks (flow shown below),
VM A <=> PowerVM Hypervisor <=> IO Server(OVS) <=> PowerVM Hypervisor
<=> VM B
In "IO server" the packet is received by inbound Trunk ibmveth and then
delivered to OVS, which is then bridged to outbound Trunk ibmveth (shown
below),
Inbound Trunk ibmveth <=> OVS <=> Outbound Trunk ibmveth
In this model, we hit the following issues which impacted the VM
communication performance,
- Issue 1: ibmveth doesn't support largesend and checksum offload features
when configured as "Trunk". Driver has explicit checks to prevent
enabling these offloads.
- Issue 2: SYN packet drops seen at destination VM. When the packet
originates, it has CHECKSUM_PARTIAL flag set and as it gets delivered to
IO server's inbound Trunk ibmveth, on validating "checksum good" bits
in ibmveth receive routine, SKB's ip_summed field is set with
CHECKSUM_UNNECESSARY flag. This packet is then bridged by OVS (or Linux
Bridge) and delivered to outbound Trunk ibmveth. At this point the
outbound ibmveth transmit routine will not set "no checksum" and
"checksum good" bits in transmit buffer descriptor, as it does so only
when the ip_summed field is CHECKSUM_PARTIAL. When this packet gets
delivered to destination VM, TCP layer receives the packet with checksum
value of 0 and with no checksum related flags in ip_summed field. This
leads to packet drops. So, TCP connections never goes through fine.
- Issue 3: First packet of a TCP connection will be dropped, if there is
no OVS flow cached in datapath. OVS while trying to identify the flow,
computes the checksum. The computed checksum will be invalid at the
receiving end, as ibmveth transmit routine zeroes out the pseudo
checksum value in the packet. This leads to packet drop.
- Issue 4: ibmveth driver doesn't have support for SKB's with frag_list.
When Physical NIC has GRO enabled and when OVS bridges these packets,
OVS vport send code will end up calling dev_queue_xmit, which in turn
calls validate_xmit_skb.
In validate_xmit_skb routine, the larger packets will get segmented into
MSS sized segments, if SKB has a frag_list and if the driver to which
they are delivered to doesn't support NETIF_F_FRAGLIST feature.
This patch addresses the above four issues, thereby enabling end to end
largesend and checksum offload support for better performance.
- Fix for Issue 1 : Remove checks which prevent enabling TCP largesend and
checksum offloads.
- Fix for Issue 2 : When ibmveth receives a packet with "checksum good"
bit set and if its configured in Trunk mode, set appropriate SKB fields
using skb_partial_csum_set (ip_summed field is set with
CHECKSUM_PARTIAL)
- Fix for Issue 3: Recompute the pseudo header checksum before sending the
SKB up the stack.
- Fix for Issue 4: Linearize the SKBs with frag_list. Though we end up
allocating buffers and copying data, this fix gives
upto 4X throughput increase.
Note: All these fixes need to be dropped together as fixing just one of
them will lead to other issues immediately (especially for Issues 1,2 & 3).

Driver maintains its primary MAC in a private field which
gets updated when ndo_dev_set_mac() gets called.
However, there are flows where the primary MAC of the device can change
without said NDO being called [bond device in TLB mode configuring
slaves' addresses], resulting in a configuration where there's a mismatch
between what's apparent to user [the netdevice's value] and what's
configured in the HW [the private value].
As we don't have any real motivation of maintaining this
private field, simply remove it and start using the netdevice's
field instead.

When management firmware declares that the device is WoL-capable,
the default driver behavior would be to allow the management firmware
to take the decision of whether it's actually needed or not.
Problem is ethtool interface doesn't have a 'default' kind
of option, and user would see the interface WoL as disabled,
which doesn't accurately reflect the actual configuration.
More-so, if the user actually wants to explicitly disable WoL he'd have
to first enable it [otherwise ethtool would block the command].
Instead of allowing management to make the decision, enable WoL by

Added helper function that checks phy_mode is RGMII (all variants)
'bool phy_interface_mode_is_rgmii(phy_interface_t mode)'
Changed the following function, to use the above.
'bool phy_interface_is_rgmii(struct phy_device *phydev)'
