If you had to resubmit this I might move the ionic driver code into a separate patch. However It can probably be accepted as is.

This patch is to define a inline function skb_csum_is_sctp(), and also replace all places where it checks if it's a SCTP CSUM skb. This function would be used later in many networking drivers in the following patches.
