Author: bz Date: Fri Apr 10 12:32:44 2009 New Revision: 190892 URL: http://svn.freebsd.org/changeset/base/190892 Log: MFC r190800: With the right comparison we get a proper wscale value and thus more adequate TCP performance with IPv6. Changes for IPv4, r166403 and r172795, both ignored the IPv6 counterpart and left it in the state of art of year 2000. The same logic in syncache already shares code between v4 and v6 so things do not need to be adapted there.
