Apologies for not writing you back sooner, this got buried in my
mailbox somehow...

The behavior is unchanged: the current HEAD (v1.0.0-1116-ga4d1250) still fails
to boot on the iMacs. Running "ifstat" from the Ctrl+B prompt references error

If I configure a static IP on the iPXE host, I see error 0x06016001. The ARP
behavior is the same as before (iPXE responds to my servers ARP requests).
The RX counter actually increments now, but no packets other than ARP
reach the server.

I also reverted to d97c6a3 and applied some patches that Cody Cutler
(CC'd) sent
me (they didn't apply to the current HEAD), which also resulted in no change. I
attached his patch for reference.

The NIC's MAC address is 40:6c:8f:34:39:f2, with PCI ID 14e4:16b4.

Let me know if there's any other information I can provide you guys with.
