Subject: [PATCH net] enic: do not call enic_change_mtu in enic_probe
Date: Mon, 30 Jul 2018 09:56:54 -0700 [thread overview]
Message-ID: <20180730165654.3816-1-gvaradar@cisco.com> (raw)
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")
