Merge branch 'sctp-fully-support-for-dscp-and-flowlabel-per-transport'
Xin Long says:
====================
sctp: fully support for dscp and flowlabel per transport
Now dscp and flowlabel are set from sock when sending the packets,
but being multi-homing, sctp also supports for dscp and flowlabel
per transport, which is described in section 8.1.12 in RFC6458.
v1->v2:
- define ip_queue_xmit as inline in net/ip.h, instead of exporting
it in Patch 1/5 according to David's suggestion.
- fix the param len check in sctp_s/getsockopt_peer_addr_params()
in Patch 3/5 to guarantee that an old app built with old kernel
headers could work on the newer kernel per Marcelo's point.
