[dpdk-dev] [PATCH 13/38] common/sfc_efx/base: add API to get mport selector by ID

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

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

The conversion is required when mport ID is received via
mport allocation and mport selector is required for filter
creation.
