[PATCH 5.4 50/61] net/mlx5e: Reduce tc unsupported key print level

From: Greg Kroah-Hartman
Date: Tue Feb 02 2021 - 13:41:11 EST


From: Maor Dickman <maord@xxxxxxxxxx>

[ Upstream commit 48470a90a42a64dd2f70743a149894a292b356e0 ]

"Unsupported key used:" appears in kernel log when flows with
unsupported key are used, arp fields for example.

OpenVSwitch was changed to match on arp fields by default that
caused this warning to appear in kernel log for every arp rule, which
can be a lot.

Fix by lowering print level from warning to debug.

Fixes: e3a2b7ed018e ("net/mlx5e: Support offload cls_flower with drop action")
