We are changing the netgraph metadata facility (in which arbitrary
metadata can be sent with a packet through processing) to use
the mbuf TAG facility that has been imported by sam.
Netgraph tags will use different cookies to the standard set of
tags imported with the code, so they will live in a separate namespace,
however they will be handled during GC and manipulation by the standard
tag handling code (Thanks to Sam for giving us the cookie facility).
In the checked in code there are only a couple of users of metadata, but
there may be 3rd parties out there that use it. If so the authors should
contact me as soon as possible to co-ordinate the changeover.
Don't forget to bump __FreeBSD_version when you make this change.
