net/mlx4_en: Fix wrong indication of Wake-on-LAN (WoL) support
Currently when WoL is supported but disabled, ethtool reports: "Supports Wake-on: d". Fix the indication of Wol support, so that the indication remains "g" all the time if the NIC supports WoL. Tested: As accepted, when NIC supports WoL- ethtool reports: Supports Wake-on: g Wake-on: d when NIC doesn't support WoL- ethtool reports: Supports Wake-on: d Wake-on: d Fixes: 14c07b1358ed ("mlx4: Wake on LAN support") Signed-off-by: Inbar Karmy <inbark@mellanox.com> Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
