I probably should mention that BSD/OS 3.0 includes support for
the Plan 9 bootp requests.

The basic code that puts out the bootp request is:

        strcpy((char *)bp->bp_vend, "p9  ");
        strcat((char *)bp->bp_vend, inet_ntoa(hp->subnet_mask));
        strcat((char *)bp->bp_vend, " ");
        strcat((char *)bp->bp_vend, inet_ntoa(hp->swap_server));
        strcat((char *)bp->bp_vend, " ");
        strcat((char *)bp->bp_vend, inet_ntoa(hp->nis_server->addr[0]));
        strcat((char *)bp->bp_vend, " ");
        strcat((char *)bp->bp_vend, inet_ntoa(hp->gateway->addr[0]));

(Please don't complain about using strcat, this was a quick hack and it
 does the job.  I probably should have used snprintf, but it is not worth
 changing it at this point.)

The fields for these entries are:

	sm	netmask, as expected
	sw	"swap server" is really your 9fs file server
	ds	dns server, as expected (only first address used)
	gw	gateway, as expected (only first address used)
