Subject: [PATCH net 1/2] macvtap: fix the missing ret value of TUNSETQUEUE
Date: Tue, 16 Jul 2013 13:36:33 +0800	[thread overview]
Message-ID: <1373952994-7252-1-git-send-email-jasowang@redhat.com> (raw)

Commit 441ac0fcaadc76ad09771812382345001dd2b813
(macvtap: Convert to using rtnl lock) forget to return what
macvtap_ioctl_set_queue() returns to its caller. This may break multiqueue API
by always falling through to TUNGETFEATURES.
