4.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Davide Caratti <dcaratti@xxxxxxxxxx>
[ Upstream commit 9264251ee2a55bce8fb93826b3f581fb9eb7e2c2 ]
commit bc8c20acaea1 ("bridge: multicast: treat igmpv3 report with
INCLUDE and no sources as a leave") seems to have accidentally reverted
commit 47cc84ce0c2f ("bridge: fix parsing of MLDv2 reports"). This
commit brings back a change to br_ip6_multicast_mld2_report() where
parsing of MLDv2 reports stops when the first group is successfully
added to the MDB cache.
Fixes: bc8c20acaea1 ("bridge: multicast: treat igmpv3 report with INCLUDE and no sources as a leave")
