[lwip-devel] [bug #56293] The callback API used to add or delete multicast MAC filter entry need some optimization

[Simon Goldschmidt]

Follow-up Comment #3, bug #56293 (project lwip):

Sigh, no patch. Ok, so I think this is a viable approach for standard MACs but
I could imagine there *are* MACs that have hardware offloading for IPv4/IPv6
available, so this should be optional.

In other words, I think it would be good to have a
'netif->multicast_mac_filter' callback and set 'igmp_mac_filter' and
'mld_mac_filter' to default callbacks that do the IPv4/IPv6-to-EthAddr
translation by default.
