Packet matching inner and outer flow rules are catch by the first one
added in the device as both flows are configured with the same priority.
To avoid such situation, the inner flow can have an higher priority than
the outer ones as their pattern matching will not collide.

A few commit log rewording suggestions for clarity and a couple of
additional comments below, otherwise patch looks fine.

I suggest dropping "priv" from everywhere in this function including its
name. It's a static helper not even exposed, no need to be consistent with
other priv* functions for the sake of consistency if the parameter is
unnecessary.

On a personal note, I noticed how complex (convoluted?) mlx5 flow rule
handling code turned lately due to all the added features, unforeseen issues
and the resulting workarounds, partly caused by the limited number of
available priorities on the Verbs side. I think we're nearing another major
rewrite.

Packet matching inner and outer flow rules are caught by the first one
added in the device as both flows are configured with the same priority.
To avoid such situation, the inner flow can have an higher priority than
the outer ones as their pattern matching will otherwise collide.

The flow is created with any steering being applied in the NIC when the
device is handling a single Rx queue.

Verbs specification does help to distinguish between packets having an VLAN
and those which do not have, this ends by having flow rule which does not
react as the user expects e.g.
flow create 0 ingress pattern eth / vlan / end action queue index 0 / end
flow create 0 ingress pattern eth / end action queue index 1 / end
are colliding in Verbs definition as in both rule are matching packets with
or without VLAN.
For this reason, the VLAN specification must not be empty, otherwise the
PMD has to refuse it.

This patch is from current release and still in next-net. If it is possible to
split this patch to fix issue in this particular commit it can be squashed into
original fix.
If not commit id for fixes will be wrong and needs to be fixed when merged into
main repo.

Can you please confirm it is safe to squash this commit [1] into [2]?
[1]: ebfe9a38cb47 ("net/mlx5: fix flow single queue")
[2]: cede123a158f ("net/mlx5: fix flow creation with a single target queue")

I confirm, [1] is a fix fixing a bug introduced in [2]. Both are needed
to fix the same bug, they should be squash in a single commit.
The confusion came from the fact commit [2] was already integrated in
shshaf's branch, when the issue was raised using another scenario.
Sorry for the confusion.
