URL: http://svn.freebsd.org/changeset/base/231471
Log:
MFC r226252:
Use the most significant 6 bits of the dscp instead of the least
significant ones.
This has changed in the latest version of the socket API ID and
provides backwards compatibility and gets it in syn with the
usage of the IP_TOS socket option.
