From: Arkadi Sharshevsky Date: Mon, 17 Jul 2017 12:15:32 +0000 (+0200) Subject: mlxsw: spectrum: Improve IPv6 unregistered multicast flooding X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9df552ef3e214e32b7a0458d3bdc430643aa553b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git mlxsw: spectrum: Improve IPv6 unregistered multicast flooding Up until now IPv6 unregistered multicast traffic would be flooded like broadcast, even when MLD snooping was enabled on the bridge. This was intentional as MLD packet traps were missing, preventing the bridge driver from programming MDB entries to the device. Previous patch added these traps, so we can now finally flood IPv6 unregistered multicast packets to specific ports via the multicast table instead of flooding them to all ports via the broadcast table.
