[lwip-users] Who is socket expert?

[revathy]

Hi,
        Iam working in BF533 APSP Blackfin processsor. In that with respect to
setsocketopt API:-

int setsockopt(int s, int level, int optname, const void *optval, int
optlen);

I wanted to know whether we have supported level namely IPPROTO_IP, where we
can do multicasting. Otherwise let me know where to enable Multicasting
option.

Iam not getting any relevant information about this from search engine.
Can anyone help me out!

Regards,
Revathy
