Intel I350 with AlmaLinux9/Grub2 Network Issue

[rweisman]

Ok this is a strange one.
I uEFI pxe boot and get a menu. When I attempt to load iPXE it fails, as it does not receive an IP.

My simple test is a file that just starts iPXE in shell mode.
When I enter dhcp from the prompt, it times out. I do see a DHCPOFFER and ACK in the var/log/messages file.

I am using dnsmasq as the DHCP server.

My previous PXE server was running Centos8 and had no issues.

My .efi file was built with snponly.efi. I also used ipxe.efi - Same Results
The i350 is a 4 port adding card, in a Dell R740xd system.
When I used a 10Gb dac cable on the base board 25Gb Broadcom it also works.

Any ideas?
