ipxe.lkrn does not detect Atheros L2 network interface

[Andromeda_x]

Hello,

I would like to express my appreciation to iPXE developers for this project.

I have followed online instructions to download latest iPXE from git and run "make" which finished successfuly.

My attempt with iPXE for floppy was successful and acomplished what I expected.

Next logical step would be to add ipxe.lkrn to my pxelinux.cfg/default configuration file which I did and ipxe.lkrn loads but it does not detect network interface.

If I attempt to issue "dhcp" command then "show errno" returns 0x2c1de03b which indicates that network interface is not found.

Well it is a strange situation that iPXE on the floppy finds and configures network interface successfully but ipxe.lkrn does not detect network interface.

I went through Makefile in hope to find what could cause this discrepancy. Looking through Makefile I did not find anything what would indicate the source of my problem.

I use Debian 7 as pxelinux.0 server and looking through "apt-cache search ipxe" I found that the distribution has iPXE package. I've installed the package and temporary substituded ipxe.lkrn -- with Debian's file ipxe.lkrn, this time network interface is detected and it can obtain IP address from DHCP server.

But as you know there is always something else be found -- ipxe.lkrn was compiled withoug "cpuid" command what makes impossible to auto select x32 or amd64 Windows 7/8/8.1/10 installation.

Hmm, what did I miss?

I went through online documentation and could not find a ponter to possible solution.

I believe that network interface is handled by atl1e driver (Fedora 25 provides driver atl2 to be used with this buildin nework interface).
