From bd89dd98b2b835bbff43f02f2e7c823eb0c61331 Mon Sep 17 00:00:00 2001 From: Jason Wang Date: Mon, 3 Aug 2015 13:20:38 +0800 Subject: virtio-net: remove useless codes After commit 40bad8f3deba15e2074ff34cfe923c12916b1cc5("virtio-net: fix used len for tx"), async_tx.len was no longer used afterwards. So remove useless codes with it. Signed-off-by: Jason Wang Reviewed-by: Michael S. Tsirkin Signed-off-by: Michael S.
