net/mlx5: fix default minimal data inline
The patch [Fixes] sets the default value of required minimal inline data to 0 bytes. On some configurations (depends on switchdev/legacy settings and FW version/settings) the ConnectX-4LX NIC requires minimal 18 bytes of Tx descriptor inline data to operate correctly. Wrongly set to 0 default value may prevent NIC from operating with out-of-the-box settings, this patch reverts default value for ConnectX-4LX back to 18 bytes (inline L2). Fixes: 9f350504bb32 ("net/mlx5: fix ConnectX-4LX minimal inline data limit") Signed-off-by: Viacheslav Ovsiienko <viacheslavo@mellanox.com> Acked-by: Matan Azrad <matan@mellanox.com>
