commit cb5c6568867325f9905e80c96531d963bec8e5ea upstream.
In commit ab123fe071c9 ("enic: handle mtu change for vf properly") ASSERT_RTNL() is added to _enic_change_mtu() to prevent it from being called without rtnl held. enic_probe() calls enic_change_mtu() without rtnl held. At this point netdev is not registered yet. Remove call to enic_change_mtu and assign the mtu to netdev->mtu.
