[PATCH net v2] virtio-net: don't disable guest csum when disable LRO
From: Tonghao Zhang <xiangxia.m.yue at gmail.com>
Open vSwitch and Linux bridge will disable LRO of the interface
when this interface added to them. Now when disable the LRO, the
virtio-net csum is disable too. That drops the forwarding performance.
