[dpdk-dev] [PATCH 1/2] net/ice/base: get PF ID of VF's parent

[dapengx.yu@intel.com]

From: Dapeng Yu <dapengx.yu@intel.com>

In original implementation, when one or more VFs are created, and VF0
is used as DCF, there is no way to get the physical function ID of their
parent adapter via VF0. The physical function ID is critical for
initializing ACL feature, if wrong physical function ID is used, the ACL
cannot be initialized successfully, and the ACL rule cannot take effect.

This patch makes VF able to get its parent's physical function ID.
