This is all the DHCP traffic, but this is coming from the Routerboot =
bios. There is a Discover, Offer, Request and ACK. Then the Routerboot =
tftps the kernel and starts to boot. Then right after the "Sending DHCP =
Discover packet from interface admsw0 (00:0c:42:07:b2:4e)" message I see =
the DHCP Release, but that's coming from the Routerboot.
