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.

Yours sincerely,
