Merge branch 'net-support-sctp-crc-csum-offload-for-tunneling-packets-in-some-drivers'
Xin Long says:
====================
net: support SCTP CRC csum offload for tunneling packets in some drivers
This patchset introduces inline function skb_csum_is_sctp(), and uses it
to validate it's a sctp CRC csum offload packet, to make SCTP CRC csum
offload for tunneling packets supported in some HW drivers.
