Subject: [PATCH mlx5-next 1/2] net/mlx5: Introduce other vport query for Q-counters

From: Patrisious Haddad <phaddad@...dia.com>

These new fields in QUERY_Q_COUNTER command allow us to access
another vport counters during the query command, which is specially
useful to query representor vports.

In addition also add the required caps to check if this capability
is actually supported.
