The actions_match_supported() function returns a bool, true for success
and false for failure. This error path is returning a negative which
is cast to true but it should return false.

For non-fatal syndromes like LOCAL_LENGTH_ERR, recovery shouldn't be
triggered. In these scenarios, the RQ is not actually in ERR state.
This misleads the recovery flow which assumes that the RQ is really in
error state and no more completions arrive, causing crashes on bad page
state.

In striding RQ mode, the buffers of an RX WQE are first
prepared and posted to the HW using a UMR WQEs via the ICOSQ.
We maintain the state of these in-progress WQEs in the RQ
SW struct.
In the flow of ICOSQ recovery, the corresponding RQ is not
in error state, hence:
- The buffers of the in-progress WQEs must be released
and the RQ metadata should reflect it.
- Existing RX WQEs in the RQ should not be affected.
For this, wrap the dealloc of the in-progress WQEs in
a function, and use it in the ICOSQ recovery flow
instead of mlx5e_free_rx_descs().

When resetting the RQ (moving RQ state from RST to RDY), the driver
resets the WQ's SW metadata.
In striding RQ mode, we maintain a field that reflects the actual
expected WQ head (including in progress WQEs posted to the ICOSQ).
It was mistakenly not reset together with the WQ. Fix this here.

Add number of WQEBBs (WQE's Basic Block) to WQE info struct. Set the
number of WQEBBs on WQE post, and increment the consumer counter (cc)
on completion.
In case of error completions, the cc was mistakenly not incremented,
keeping a gap between cc and pc (producer counter). This failed the
recovery flow on the ICOSQ from a CQE error which timed-out waiting for
the cc and pc to meet.

Termination tables change the direction of a packet in hw from RX to SX
pipeline. Use that to offload hairpin flows received from uplink and
sent back to uplink.
Currently termination tables are used for pushing VLAN to packets
received from uplink and targeting a VF. Extend the implementation to
allow forwarding packets to uplink. These packets can either be
encapsulated or not.
In case encapsulation is needed before forwarding, move the reformat
object to the termination table as required.
Extend the hash table key to include tunnel information for the sake of
reusing reformat objects.

If udevd is configured to rename interfaces according to persistent
naming rules and if a network interface has phys_port_name in sysfs,
its contents will be appended to the interface name.
However, register_netdev creates device in sysfs and if
devlink_port_register is called after that, there is a timeframe in
which udevd may read an empty phys_port_name value. The consequence is
that the interface will lose this suffix and its name will not be
really persistent.
The solution is to register the port before registering a netdev.

Currently, flow tables are automatically connected according to their
<chain,prio,level> tuple.
Introduce global tables which are flow tables that are detached from the
eswitch chains processing, and will be connected by explicitly referencing
them from multiple chains.
Add this new table type, and allow connecting them by refenece.

The eswitch offloads table, which has the reps (vport) rx miss rules,
was moved from OFFLOADS namespace [0,0] (prio, level), to [1,0], so
the restore table (the new [0,0]) can come before it. The destinations
of these miss rules is the rep root ft (ttc for non uplink reps).
Uplink rep root ft is created as OFFLOADS namespace [0,1], and is used
as a hook to next RX prio (either ethtool or ttc), but this fails to
pass fs_core level's check.
Move uplink rep root ft to OFFLOADS prio 1, level 1 ([1,1]), so it
will keep the same relative position after the restore table
change.
