Hi,
There was a patch
(http://lists.xenproject.org/archives/html/xen-devel/2015-09/msg00285.html) in
2015 to support multicast packet filter in Xen netback. I found that this
feature "feature-multicast-control" is currently not supported by Xen netfront
in mainline linux.

Trying to batch Tx response events results in poor performance because
this delays freeing the transmitted skbs.
Instead use the standard RING_FINAL_CHECK_FOR_RESPONSES() macro to be
notified once the next Tx response is placed on the ring.
