[X]: This bug persists when memory is increased beyond 8GB.

Describe the bug

I have a IPv6-only network and netboot.xyz don't work at all.
I created another VLAN with IPv4 and NAT, just for netboot purposes.

I define one custom VLAN and IP, the "netboot menu" works and opens.

However, I can't install AlmaLinux and almost any other OS.
When I tried the "memtest" utility it works, but AlmaLinux doesn't fetch contents.

To Reproduce
Steps to reproduce the behavior:

Press 'm'
In iPXE menu, set VLAN, IP and DNS
Select "Linux Network Installs"
Select "AlmaLinux"
It will show "VLAN 0" in the logs (ignoring the VLAN defined in step 2). Download will fail.

Note: Your VLAN 0 (and network without VLAN) needs to be IPv6-only or don't have connections at all.

Expected behavior

The AlmaLinux install process must use the same VLAN, IP and DNS defined in iPXE.
