Hi Jakub,

Thanks for checking.

I have the feeling this bot got confused somehow, maybe it does
not fully get how things got restructured in
br_multicast_querier_exists(), __br_multicast_querier_exists()
and the newly added br_multicast_snooping_active()?

I'm not adding or moving any "const bool is_ipv6" anymore. Au
contraire, I'm explicitly removing the "const" in is_ipv6 to
__br_multicast_querier_exists() while restructuring
things in [PATCH v2 13/14] now?

I think I also followed this one, too? In [PATCH v2 13/14] I'm
removing passing a "struct ethhdr *eth" and am instead passing an
"int proto" to br_multicast_querier_exists() and an
"__be16 eth_proto" to br_multicast_snooping_active()?


(I'm also unsure why this reply was to this patch and not
[PATCH v2 13/14] ->
https://patchwork.kernel.org/project/netdevbpf/patch/20260206030123.5430-14-linus.luessing@xxxxxxxxx/)
