[lwip-users] IPv6 multicast support by Socket API?

[Andrej Butok]

Hello lwIP developers,

I am using latest  lwIP 2.0.2.
My application have to use lwIP Socket user API and FreeRTOS. And It have to 
join IPv4 and IPv6 multicast groups.
The IPv4 Multicast is supported very well via  the IP_ADD_MEMBERSHIP / 
IP_DROP_MEMBERSHIP socket options.
BUT it looks like the lWIP Sockets does not support IPv6 multicast join/leave.

Did I miss something?
Are you going to add this missing functionality? 
Any suggestion how to work around this issue now?

Thank you,
Andrey
