From 078e049c49a6096cd55a1248f2caee0fce135646 Mon Sep 17 00:00:00 2001 From: Alexander Lobakin Date: Wed, 1 Mar 2023 12:59:07 +0100 Subject: [PATCH] iavf: fix inverted Rx hash condition leading to disabled hash [ Upstream commit 32d57f667f871bc5a8babbe27ea4c5e668ee0ea8 ] Condition, which checks whether the netdev has hashing enabled is inverted. Basically, the tagged commit effectively disabled passing flow hash from descriptor to skb, unless user *disables* it via Ethtool. Commit a876c3ba59a6 ("i40e/i40evf: properly report Rx packet hash") fixed this problem, but only for i40e. Invert the condition now in iavf and unblock passing hash to skbs again.
