There is one valid reason for which you should get this: your lksctp
userspace lib version is older and does not support SCTP_DELAYED_SACK,
while the kernel is newer (>=2.6.27).

However you will get this even if you have the latest lksctp, because
the lksctp has a typo in it and defines/uses SCTP_DELAYED_ACK instead of
SCTP_DELAYED_SACK (I'll report it).

I'll come up with some sort of a linux specific workaround for this.
