ipxe device initialization drops first port

[NiKiZe]

A few first pieces of information that you should provide:
What is the pciid or chip on the nic that you are expecting to see? (best way to find it is to use linux lspci -nn)

Also make sure that you provide information about which binary is used - in this case we can see it being ipxe.efi from the top of the screen,we can also see that most of the devices are using SNP driver - which might actually mean that it is snp.efi renamed

SNP is the driver provided by firmware - so in this case I would assume that there is no NIC firmware for the port you want to see, or that ROM is disabled in BIOS or similar.
It might also be that there is something preventing iPXE from taking control over that NIC/port, there are some posts about unable to unload existing drivers and similar - if that is the case it should be reported as a firmware bug to the MB or hardware manufacturers.

Also it is always a good idea to test latest git master, and do test ipxe.efi, you can also find it at boot.ipxe.org if you don't want to build yourself - I'm not saying that you should just switch, but make a backup of current ipxe.efi that you are using and test with the latest ipxe.efi, take notes of what you are seeing, and than restore the backup, from there let's figure out next step.

Also your current ipxe binary is built without git tools available - so we have no idea from when that is (Which version it is)
