From: Stefan Hajnoczi <redacted> In order for other vhost devices to use the VHOST_FEATURES bits the vhost-net specific bits need to be moved to their own VHOST_NET_FEATURES constant. (Asias: Update drivers/vhost/test.c to use VHOST_NET_FEATURES) Signed-off-by: Stefan Hajnoczi <redacted> Cc: Zhi Yong Wu <redacted> Cc: Michael S.
