Subject: [PATCH AUTOSEL 4.14 17/35] ibmvnic: Refresh device multicast list after reset
Date: Wed, 26 Jun 2019 20:39:05 -0400
Message-ID: <20190627003925.21330-17-sashal@kernel.org> (raw)
In-Reply-To: <20190627003925.21330-1-sashal@kernel.org>

From: Thomas Falcon <tlfalcon@linux.ibm.com>

[ 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.
