[dpdk-dev] [PATCH 1/4] net/bnxt: configure loopback parif for full offload egress flows

[Somnath Kotur]

From: Kishore Padmanabha <kishore.padmana...@broadcom.com>

The full offload egress flows for the VF rep interface should
use loopback parif to offload missed flows.

Fixes: fe82f3e02701 ("net/bnxt: support exact match templates")
