net/mlx4_en: Use ethtool cmd->autoneg as a hint for ethtool set settings
Use cmd->autoneg as a user hint to decide what to set in ethtool set settings callback.
When cmd->autoneg == AUTONEG_ENABLE set according to ethtool->advertise otherwise,
set according to ethtool->speed.
Usage:
- ethtool -s eth<x> speed 56000 autoneg off
- ethtool -s eth<x> advertise 0x800000 autoneg on
While we're here:
- Move proto_admin masking outcome check to be adjacent to the operation.
- Move en_warn("port reset..") print to "port reset" block.
Fixes: 312df74 ("net/mlx4_en: mlx4_en_set_settings() always fails when autoneg is set")
