sctp: add SCTP_REMOTE_UDP_ENCAPS_PORT sockopt
This patch is to implement:
rfc6951#section-6.1: Get or Set the Remote UDP Encapsulation Port Number
with the param of the struct:
struct sctp_udpencaps {
sctp_assoc_t sue_assoc_id;
struct sockaddr_storage sue_address;
uint16_t sue_port;
};
the encap_port of sock, assoc or transport can be changed by users,
which also means it allows the different transports of the same asoc
to have different encap_port value.
v1->v2:
- no change.
v2->v3:
- fix the endian warning when setting values between encap_port and
sue_port.
