From 99753ea60626a4c5059b24e2a4c22f8fd88b8207 Mon Sep 17 00:00:00 2001 From: Jesse Brandeburg Date: Wed, 4 Jun 2014 04:22:49 +0000 Subject: [PATCH] i40e: fix fdir programming There were a couple of fields in the fdir descriptor setup that were not being reprogrammed, which left the opportunity for stale data to be pushed as part of the descriptor next time it was used.
