From f32f5aee9effafd14b24a6a17e537a994f77063c Mon Sep 17 00:00:00 2001 From: Jeff Guo Date: Mon, 24 Oct 2016 22:42:36 -0400 Subject: [PATCH] net/i40e: fix hash filter on X722 When verifying the Hash filtering on X722, we found a problem that the hash value in descriptor is incorrect. The root cause is that X722 uses different way of hash key word selection compared with X710/XL710. This patch fixes it by setting X722 specific key selection.
