Bug Description

* Explain the bug
After the CT ifindex extension feature, flow table entries are
populated with ifindex information which was intended to only be used
for HW offload. This tuple ifindex is hashed in the flow table key, so
it must be filled for lookup to be successful. But tuple ifindex is only
relevant for the netfilter flowtables (nft), so it's not filled in
act_ct flow table lookup, resulting in lookup failure, and no SW
offload and no offload teardown for TCP connection FIN/RST packets.

To fix this, add new tc ifindex field to tuple, which will
only be used for offloading, not for lookup, as it will not be part of the tuple hash.

* How to test
Create OVS bridge with 2 devices mlx5 rep devices.
Enable HW offload and configure regular connection tracking OpenFlow rules:

e.g:
    ovs-ofctl del-flows br-ovs
    ovs-ofctl add-flow br-ovs arp,actions=normal
    ovs-ofctl add-flow br-ovs "table=0, ip,ct_state=-trk actions=ct(table=1)"
    ovs-ofctl add-flow br-ovs "table=1, ip,ct_state=+trk+new actions=ct(commit),normal"
    ovs-ofctl add-flow br-ovs "table=1, ip,ct_state=+trk+est, actions=normal"

Generate traffic at high rate (e.g. using IXIA).
The number of offloaded rules exposed in /sys/kernel/debug/mlx5/0000\:$BUS\:00.0/ct/offloaded should be in synch the number of generated connections.

* What it could break.
Perhaps nft offload – it is not part of our tests

This bug is awaiting verification that the linux-bluefield/5.4.0-1033.36 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
