net/mlx5: fix master device Netlink socket sharing
There is the patch [1] that uses master device Netlink socket to retrieve master device link settings. This is not thread safe because this resource may be in use by other call to the master device itself. Using the same Netlink socket concurrently from the multiple threads causes Netlink requests malfunction and must be eliminated. The patch replaces master Netlink socket with the socket from representor device. [1] http://patches.dpdk.org/patch/53120/ Fixes: 0333b2f584d9 ("net/mlx5: inherit master link settings for representors") Cc: stable@dpdk.org Signed-off-by: Viacheslav Ovsiienko <viacheslavo@mellanox.com> Acked-by: Shahaf Shuler <shahafs@mellanox.com>
