> With the newly introduced helper functions the skb pulling is hidden in
> the checksumming function - and undone before returning to the caller.
> The IGMPv3 and MLDv2 report parsing functions in the bridge still
> assumed that the skb is pointing to the beginning of the IGMP/MLD
> message while it is now kept at the beginning of the IPv4/6 header,
> breaking the message parsing and creating packet loss.
> Fixing this by taking the offset between IP and IGMP/MLD header into
> account, too.
> Fixes: 9afd85c9e455 ("net: Export IGMP/MLD message validation code")
