Author: jhb Date: Wed Jan 23 21:44:48 2013 New Revision: 245849 URL: http://svnweb.freebsd.org/changeset/base/245849
Log: Don't assume that all Linux TCP-level socket options are identical to FreeBSD TCP-level socket options (only the first two are). Instead, using a mapping function and fail unsupported options as we do for other socket option levels.
