New Revision: 207983
URL: http://svn.freebsd.org/changeset/base/207983
Log:
More PR-SCTP bugs:
- Make sure that when you kick the streams you add correctly
using a 16 bit unsigned.
- Make sure when sending out you allow FWD-TSN to skip over
and list the ACKED chunks in the stream/seq list (so the
rcv will kick the stream)
