DCHP fail w/ Intel i210 lan port in Boradwell-EP platform

[dennis.huang]

Hi ,
We see a strange behavior w/ ipxe in Intel Broadwell -EP platform (PCH :8900).
We have 2 I210 lan w/ NCSI , one is 5:0:0(port 1) another one is 6:0:0(port 2).
We can get dhcp ip from dhcp server through port 1 , but port 2 can't get dhcp ip from dhcp server.
In Port 2 , ipxe will try to do dhcp discovery and cause timeout w/ debug mode .(error code :28086011 and 040ee119)
When I use the tftp server to get pxelinux.0 and boot w/o IPXE , both ports can download image and remote boot correctly.

(my dhcp server is Centos 6.6)
I also try to use other platform (Broadwell-DE soc) w/ 2 I210 lan w/ NCSI (8086:1533) , one is 8:0:0(port 1) another one is

9:0:0(port 2).
Both ports are workable for boot w/ ipxe (dhcp action can be finished).
I also find other Broadwell-EP board w/ I210 (PCH:C610),the issue still happen.
When I find a Broadwell-EP board w/ I350 (PCH:C610 ), I can boot correctly .
(PCIE bdf is 8:0:2 and 8:03)

May I have your suggestion or comment ? or someone also saw the same issue before .

Thanks!
B/R
Dennis
