This patchset is to add support for 3 msg_control options described
in RFC6458:
5.3.7. SCTP PR-SCTP Information Structure (SCTP_PRINFO)
5.3.9. SCTP Destination IPv4 Address Structure (SCTP_DSTADDRV4)
5.3.10. SCTP Destination IPv6 Address Structure (SCTP_DSTADDRV6)
one send flag described in RFC6458:
SCTP_SENDALL: This flag, if set, will cause a one-to-many
style socket to send the message to all associations that
are currently established on this socket. For the one-to-
one style socket, this flag has no effect.
Note there is another msg_control option:
5.3.8. SCTP AUTH Information Structure (SCTP_AUTHINFO)
It's a little complicated, I will post it in another patchset after
this.
