[ipxe-devel] Dell C6220 lkrn MAC address issue / Intel I350

[Matthew Drobnak]

When chainloaded from pxelinux as the ipxe.lkrn module, the following 
occurs:

iPXE> Note that the correct MACs end in "e3" and "e4". So, something 
strange is happening when using the "Linux kernel" version of iPXE. Only 
seems to be happening on I350 based cards. We have two other Dell "Cloud 
Series" servers, the C6100 and C2100 series, which have no issues at 
all. Hopefully this helps find this bug. Please let me know if you need 
any more information. Thanks. -Matt
