[OpenWrt-Devel] AA: IPv6 bug on TP-Link TL-WR841N v8 (patch available)

Hi,

There is a bug in AA regarding IPv6 multicast support for the AR9341
switch (at least on a TP-Link TL-WR841N v8 device).  Basically, it breaks
IPv6 Neighbour Discovery, which seriously limits IPv6 functionality.

See this ticket:

  https://dev.openwrt.org/ticket/15448

In particular, a patch is available:

  https://dev.openwrt.org/attachment/ticket/15448/0001-AR934X-Enable-unicast-multicast-flooding-to-the-CPU-.patch


Is it possible to apply this patch to the AA branch?

I have been using this patch for two months now, applied to the latest AA,
and it works fine.  I've used it on multiple TL-WR841N v8, in particular
during a large event with hundreds of IPv6 wireless clients.

Thanks a lot,
Baptiste
