From 501c774cb13c3ef8fb7fc5f08fa19473f7d9a0db Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 18 Feb 2010 05:46:50 +0000 Subject: net/macvtap: add vhost support This adds support for passing a macvtap file descriptor into vhost-net, much like we already do for tun/tap. Most of the new code is taken from the respective patch in the tun driver and may get consolidated in the future. Signed-off-by: Arnd Bergmann Acked-by: Sridhar Samudrala Signed-off-by: David S.
