iPXE shell not showing any interface after booting with ipxe.efi

[nswami]

After downloading the ipxe source code, built the ipxe.efi with "make bin-x86_64-efi/ipxe.efi" with a EMBEDDED script to drop to ipxe shell. When i look at "ifstat" it shows no interfaces. I've onboard Intel X550-T2 NIC in the system and looking at another post, the following is enabled in driver code.

PCI_ROM ( 0x8086, 0x1563, "x550t2", "X550-T2", 0 ),

I'm new to this iPXE stuff and intention is to build iPXE.efi to chain load the OS. Can someone pls help to build appropriate target to handle this ?
