- Adapt layer indication was always being given (it should only
be given when the user has enabled it). (Michael Tuexen) - Sack Immediately was not being set properly on the actual chunk, it was only put in the rcvd_flags which is incorrect. (Michael Tuexen) - added an ifndef userspace to one of the already present macro's for inet (Brad Penoff) Obtained from: Michael Tuexen and Brad Penoff MFC after: 4 weeks
