net/mlx5e: aRFS, Introduce ethtool stats
Improve aRFS observability by adding new set of counters. Each Rx ring will have this set of counters listed below. These counters are exposed through ethtool -S. 1) arfs_add: number of times a new rule has been created. 2) arfs_request_in: number of times a rule was requested to move from its current Rx ring to a new Rx ring (incremented on the destination Rx ring). 3) arfs_request_out: number of times a rule was requested to move out from its current Rx ring (incremented on source/current Rx ring). 4) arfs_expired: number of times a rule has been expired by the kernel and removed from HW. 5) arfs_err: number of times a rule creation or modification has failed. This patch removes rx[i]_xsk_arfs_err counter and its documentation in mlx5/counters.rst since aRFS activity does not occur in XSK RQ's.
