Subject: [dpdk-stable] [PATCH 1/2] net/mlx5: fix link status query
Date: Wed, 25 Jan 2017 14:42:58 +0200 [thread overview]
Message-ID: <1485348178-43771-1-git-send-email-shahafs@mellanox.com> (raw)
Trying to query the link status through new kernel ioctl API
ETHTOOL_GLINKSETTINGS was always failing due to kernel bug.
The bug was fixed on version 4.9
this patch uses the legacy ioctl API for lower kernels.
Fixes: 188408719888 ("net/mlx5: fix support for newer link speeds")

while the ETHTOOL_GLINKSETTINGS API was introduced on kernel v4.6 [1]
the bug was fixed only on kernel v4.9 [2]
