Subject: [PATCH net] net: dsa: return after mdb prepare phase
Date:   Wed,  8 Nov 2017 10:49:56 -0500
Message-Id: <20171108154956.23898-1-vivien.didelot@savoirfairelinux.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The current code does not return after successfully preparing the MDB
addition on every ports member of a multicast group. Fix this.

Fixes: a1a6b7ea7f2d ("net: dsa: add cross-chip multicast support")
