[Linaro-uefi] UEFI Shell Command "ifconfig" Error

Hello,

I am trying to add an ethernet driver to UEFI. It is using PCI IO protocol and producing SNP. When I issue "ifconfig -l eth0" command in UEFI shell, I get an error:

Error. The protocol 'gEfiIp4ConfigProtocolGuid' was required and not found (3B95AA31-3793-434B-8667-C8070892E05E).

I have copied the networking stack set up from ArmVExpress.dsc.inc and ArmVExpress-networking.fdf.inc that includes the Ip4ConfigDxe.inf module. What am I missing ?

Thanx, Narinder
