Subject: [PATCH net] macvtap: fix tx_dropped counting error
Date: Mon, 25 Nov 2013 17:19:04 +0800 [thread overview]
Message-ID: <1385371144-11071-1-git-send-email-jasowang@redhat.com> (raw)
After commit 8ffab51b3dfc54876f145f15b351c41f3f703195
(macvlan: lockless tx path), tx stat counter were converted to percpu stat
structure. So we need use to this also for tx_dropped in macvtap. Otherwise, the
management won't notice the dropping packet in macvtap tx path.
