4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Davide Caratti <[email protected]> [ 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.
