From linux-4.2 there's a "hw csum failure" for bridges using hardware
checksums when IPv6 multicast traffic is received.
Here are some reports:

https://bugzilla.redhat.com/show_bug.cgi?id=1266601
https://discourse.osmc.tv/t/hw-csum-failure/9990
https://github.com/raspberrypi/linux/issues/1259
I think it may have been introduced in commit
9afd85c9e4552b276e2f4cfefd622bdeeffbbf26 (net: Export IGMP/MLD message
validation code) but I haven't done any tests to confirm it.
Any help on this issue would be really appreciated.
Regards,
Álvaro.
