From: Thomas Falcon <redacted> [ 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 <redacted> Signed-off-by: David S.
