History
Luigi Rizzo 49b144f286 Add a readonly sysctl variable of type string, kern.bootp_cookie, 
which is initialized with whatever string a dhcp/bootp server passes
as vendor tag 134.
There is no standard tag that I know with this information, and
no vendor-defined tag that applies to FreeBSD that I could find
doing the same thing.

The intended use is to pass information to userland for run-time
configuration of a diskless client without having to run a bootp/dhcp
client for the third time (after the one in pxeboot/etherboot, and
the one in the kernel bootp), also because these clients generally
screwup the interface configuration, which is not exactly what you
want when you have your disks nfs-mounted.

Manpage update to follow soon.
