Subject: bridge: re-introduce 'fix parsing of MLDv2 reports'
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9264251ee2a55bce8fb93826b3f581fb9eb7e2c2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

bridge: re-introduce 'fix parsing of MLDv2 reports'

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.
