Author: kib Date: Sun Feb 26 13:55:43 2012 New Revision: 232179 URL: http://svn.freebsd.org/changeset/base/232179 Log: Add SO_PROTOCOL/SO_PROTOTYPE socket SOL_SOCKET-level option to get the socket protocol number. This is useful since the socket type can be implemented by different protocols in the same protocol family, e.g. SOCK_STREAM may be provided by both TCP and SCTP. Submitted by: Jukka A.
