From c3582a2c4d0baf1fa3955c8b3d3d61308df474c7 Mon Sep 17 00:00:00 2001 From: Haiyang Zhang Date: Mon, 1 Dec 2014 13:28:39 -0800 Subject: hyperv: Add support for vNIC hot removal This patch adds proper handling of the vNIC hot removal event, which includes a rescind-channel-offer message from the host side that triggers vNIC close and removal. In this case, the notices to the host during close and removal is not necessary because the channel is rescinded. This patch blocks these unnecessary messages, and lets vNIC removal process complete normally. Signed-off-by: Haiyang Zhang Reviewed-by: K. Y. Srinivasan Signed-off-by: David S.
