From ae8524861443d7e7f74145f722d9641883190943 Mon Sep 17 00:00:00 2001 From: Thomas Falcon Date: Fri, 7 Jun 2019 16:03:54 -0500 Subject: [PATCH] ibmvnic: Refresh device multicast list after reset [ Upstream commit be32a24372cf162e825332da1a7ccef058d4f20b ] It was observed that multicast packets were no longer received after a device reset. The fix is to resend the current multicast list to the backing device after recovery. Signed-off-by: Thomas Falcon Signed-off-by: David S.
