From: Tonghao Zhang <xiangxia.m.yue at gmail.com> Allow user configuring RXCSUM separately with ethtool -K, reusing the existing virtnet_set_guest_offloads helper that configures RXCSUM for XDP.

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. Fixes: e59ff2c49ae1 ("virtio-net: disable guest csum during XDP set") Cc: Michael S.
