Author: peterj Date: Wed Dec 31 00:08:37 2014 New Revision: 276434 URL: https://svnweb.freebsd.org/changeset/base/276434 Log: MFH r230580: Don't mention no longer supported ioctl commands. MFH r274083: convert .Nm to proper .Xr's... MFH r275298: Cross reference tap(4) and tun(4) and include a short explanation as to how they differ. This will assist users in selecting which interface is more appropriate for their purposes.
