From 219419510c4e6c49f19490dd56c0254f55f3b740 Mon Sep 17 00:00:00 2001 From: Chris Mi Date: Tue, 14 Dec 2021 03:52:53 +0200 Subject: [PATCH] net/mlx5: Fix tc max supported prio for nic mode [ Upstream commit d671e109bd8548d067b27e39e183a484430bf102 ] Only prio 1 is supported if firmware doesn't support ignore flow level for nic mode. The offending commit removed the check wrongly. Add it back.
