Subject: [PATCH net-next v2 06/14] sfc: display vadaptor statistics for all
interfaces
From: Daniel Pieczko <dpieczko@...arflare.com>
All interfaces will display vadaptor statistics, so set all the
relevant bits in the stats bitmask. Only functions with the
LINKCTRL flag will see other stats, including (per-port) MAC stats.
The vadaptor stats are from rx_unicast to tx_overflow.
