Subject: common/sfc_efx/base: add API to get mport of PF/VF
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=097058033f034365d124cf93acda6947036f4aa7;p=dpdk.git

common/sfc_efx/base: add API to get mport of PF/VF

PCIe functions have static MPORTs which can be utilised by
MAE rules as delivery destinations for matching traffic.
