[ipxe-devel] iPXE concurrent use of two interfaces in different subnets not working

[Laborde, Louis (HP Servers)]

Hello iPXE developers,

I am trying to get iPXE to concurrently use two interfaces each in their own subnet on my 2-port Mellanox adapter:
1st subnet on net0 for access to the SAN device, and 2nd subnet on net1 for access to the PXE server to deploy the OS
(WDS to deploy Windows).

The problem is that after discovering the not bootable SAN device on net0, and trying to PXE boot over net1, iPXE can't
access the SAN device anymore on net0, and the PXE boot over net1 fails.

Here is the spew seen on the console:

net0: a0:1d:48:b5:00:e4 using ConnectX3 on PCI01:00.0 (open)
  [Link:down, TX:0 TXE:0 RX:0 RXE:0]
