From 09a04204f041caff7717a001a16c376f73be731b Mon Sep 17 00:00:00 2001 From: Bert Kenward Date: Wed, 23 Dec 2015 08:58:15 +0000 Subject: [PATCH] sfc: Downgrade or remove some error messages Depending on configuration the NIC may return errors for unprivileged functions and/or VFs. Where these are expected and handled, reduce the level of any output. Signed-off-by: Bert Kenward Signed-off-by: David S.
