Author: mav Date: Mon Dec 25 00:25:15 2017 New Revision: 327170 URL: https://svnweb.freebsd.org/changeset/base/327170 Log: MFC r326186: Slightly fix bidirectional stream number allocation. This logic is still imperfect, since it allows at most 15 bidirectional streams out of 30 allowed by specification, but at least now those should work better. On the other side I don't remember I ever saw controller supporting the bidirectional streams, so this is likely a nop change.
