[dpdk-dev] [PATCH v4] net/ice/base: get PF ID of VF's parent

[dapengx.yu@intel.com]

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

In original implementation, if DCF is created on PF1, the PF ID is
still 0, but not 1. Without the right PF ID, the ACL will not work.

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

Fixes: 0b02c9519432 ("net/ice: handle PF initialization by DCF")
