Subject: Re: man-pages-3.55 is released

Hi,

Excerpt from http://man7.org/linux/man-pages/man2/socket.2.html :

       Some socket types may not be implemented by all protocol families;
       for example, SOCK_SEQPACKET is not implemented for AF_INET.

This is not correct now, as Linux already had SCTP support.

Excerpt from http://tools.ietf.org/html/rfc6458#section-3.1.1 :

   and one uses PF_INET or PF_INET6 as the domain, SOCK_SEQPACKET as the
   type, and IPPROTO_SCTP as the protocol.

   Here, SOCK_SEQPACKET indicates the creation of a one-to-many style
   socket.

Regards,
Dongsheng
