Is the network card's PXE implementation able to get a DHCP lease right
away, or does it also take a while?
What we noticed is that most network card PXE implementations have much
higher timeouts than iPXE, and do not give up that easily.
When iPXE initializes the network card, it seems the network link
briefly goes down and up again, and this causes STP-enabled switches to
start the waiting period over again.
