Here are some reports: https://lkml.org/lkml/2015/12/1/699 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.
