bootp support wildcard hardware address

[Jacky]

Hi,

I have used PXELinux with dhcpd and the client boots up OK with the following configuration:

subnet 192.168.1.0 netmask 255.255.255.0 {
	range 192.168.1.100 192.168.1.120;
	option subnet-mask 255.255.255.0;
}

host llama0 {
	hardware ethernet 00:11:22:34:56:77;
	filename "pxelinux.0";
}

The problem is: I don't know in advance what is the bootp client's MAC address (i.e. I want to boot any client).

I tried remove the "hardware" line but the client failed to boot.
Is there anyway to put a wildcard MAC address in settings.

Thanks a lot,

Jacky
