Subject: [PATCH] ibmvnic: Refresh device multicast list after reset
References: bsc#1137752
Patch-mainline: v5.2-rc6
Git-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.
