Subject: [dpdk-dev] [PATCH] net/mlx5: fix use of bit numbers instead of masks
Date: Fri, 10 Nov 2017 14:18:04 +0000 [thread overview]
Message-ID: <20171110141746.19251-1-makarov@kraftway.ru> (raw)
The constant ETHTOOL_LINK_MODE_1000baseT_Full_BIT and the others like
that in mlx5_link_update_unlocked_gs must be bit masks but unfortunately
they are bit numbers. This commit fixes the issue.
Fixes: 188408719888 ("net/mlx5: fix support for newer link speeds")
