net/mlx4_en: Show PF own statistics via ethtool
Allow the user to observe the PF own statistics using ethtool with pf_
prefixed counter names.
Those counters are the PF statistics out of the overall port statistics.
Every PF QP is attached to a counter and the summary of those counters
is the PF statistics.
