4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Govindarajulu Varadarajan <gvaradar@xxxxxxxxx>
[ Upstream commit cb5c6568867325f9905e80c96531d963bec8e5ea ]
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.
Fixes: ab123fe071c9 ("enic: handle mtu change for vf properly")
