-Subject: [PATCH] virtio: tx with can_push when VERSION_1 is set
-
-Current virtio driver advertises VERSION_1 support,
-but does not handle device's VERSION_1 support when
-sending packets (it looks for ANY_LAYOUT feature,
-which is absent).
-
-This patch enables 'can_push' in tx path when VERSION_1
-is advertised by the device.
-
-This significantly improves small packets forwarding rate
-towards devices advertising VERSION_1 feature.
