PF and AF (admin function) shares 64KB of reserved memory region for
communication. This region is shared for
- Messages sent by PF and responses sent by AF.
- Notifications sent by AF and ACKs sent by PF.
This patch adds infrastructure to handle notifications sent
by AF and adds handlers to process them.
One of the main usecase of notifications from AF is physical
link changes. So this patch adds registration of PF with AF
to receive link status change notifications and also adds
the handler for that notification.

This patch adds the packet transmission support.
For a given skb prepares send queue descriptors (SQEs) and pushes them
to HW. Here driver doesn't maintain it's own SQ rings, SQEs are pushed
to HW using a silicon specific operations called LMTST. From the
instuction HW derives the transmit queue number and queues the SQE to
that queue. These LMTST instructions are designed to avoid queue
maintenance in SW and lockless behavior ie when multiple cores are trying
to add SQEs to same queue then HW will takecare of serialization, no need
for SW to hold locks.
Also supports scatter/gather.

Completion queue (CQ) is the one with which HW notifies SW on a packet

notifications are processed.

For a PF to function as a NIC, NPA (for Rx buffers, Tx descriptors etc)
and NIX (for rcv, send and completion queues) are the minimum resources
needed. So request admin function (AF) to attach one each of NIX and NPA
block LFs (local functions).
Only AF can configure a LF's contexts, so request AF to allocate memory
for NPA aura/pool and NIX RQ/SQ/CQ HW contexts. Upon receiving response,
save some of the HW constants like number of pointers per stack page,
size of send queue buffer (SQBs, where SQEs are queued by HW) e.t.c which
are later used to initialize queues.
A HW context here is like a state machine maintained for a descriptor
queue. eg size, head/tail pointers, irq etc etc. HW maintains this in

In order to stop useless driver version bumps and unify output
presented by ethtool -i, let's set default version string.
As Linus said in [1]: "Things are supposed to be backwards and
forwards compatible, because we don't accept breakage in user
space anyway. So versioning is pointless, and only causes
problems."
They cause problems when users start to see version changes
and expect specific set of features which will be different
for stable@, vanilla and distribution kernels.
Distribution kernels are based on some kernel version with extra
patches on top, for example, in RedHat world this "extra" is a lot
and for them your driver version say nothing. Users who run vanilla
kernels won't use driver version information too, because running
such kernels requires knowledge and understanding.
Another set of problems are related to difference in versioning scheme
and such doesn't allow to write meaningful automation which will work
sanely on all ethtool capable devices.
Before this change:
[leonro@erver ~]$ ethtool -i eth0
driver: virtio_net
version: 1.0.0
After this change and once ->version assignment will be deleted
from virtio_net:
[leonro@server ~]$ ethtool -i eth0
driver: virtio_net
version: 5.5.0-rc6+

====================
When I tried a test based on the selftest program for BPF flow dissector
(test_flow_dissector.sh), I observed unexpected result as below:
$ tc filter add dev lo parent ffff: protocol ip pref 1337 flower ip_proto \
udp src_port 8-10 action drop
$ tools/testing/selftests/bpf/test_flow_dissector -i 4 -f 9 -F
inner.dest4: 127.0.0.1
inner.source4: 127.0.0.3
pkts: tx=10 rx=10
The last rx means the number of received packets. I expected rx=0 in this
test (i.e., all received packets should have been dropped), but it resulted
in acceptance.
Although the previous commit 8ffb055bea ("cls_flower: Fix the behavior
using port ranges with hw-offload") added new flag and field toward filtering
based on port ranges with hw-offload, it missed applying for BPF flow dissector
then. As a result, BPF flow dissector currently stores data extracted from
packets in incorrect field used for exact match whenever packets are classified
by filters based on port ranges. Thus, they never match rules in such cases
because flow dissector gives rise to generating incorrect flow keys.
This series fixes the issue by replacing incorrect flag and field with new
ones in BPF flow dissector, and adds a test for filtering based on specified
port ranges to the existing selftest program.
Changes in v2:
