[dpdk-dev] [PATCH 12/38] common/sfc_efx/base: add filter ingress mport matching field

[Andrew Rybchenko <andrew.rybchenko@oktetlabs.ru>]

From: Igor Romanov <igor.romanov@oktetlabs.ru>

The field changes the mport for which the filter is created.
It is required to filter traffic from VF on an alias mport.
