arm kernel does not support SCTP?

[Paul Wouters]

I'm updating socat to run all its test cases, and I'm running into an
error only on the arm architecture:

test 151 SCTP4LISTENFORK: SCTP4 listen handles 2 concurrent
connections... !port 40157 timed out! FAILED
2014/04/09 01:36:12 server[6004] E socket(2, 1, 132): Protocol not supported
2014/04/09 01:36:14 client[6021] E socket(2, 1, 132): Protocol not supported
2014/04/09 01:36:15 client[6030] E socket(2, 1, 132): Protocol not supported
1,3d0

Is this a known issue or feature? Is SCTP disabled in the arm kernel on
purpose?
