When I use "dh -v" command it does not dump the protocol handles.The "help dh" 
command does say that protocol handles can be dumped using GUID but I cannot 
seem to find the format for the 128-bit value that would make the UEFI Shell 
happy.Thanx.

fixed it but did not make things better.I tried to debug this further with 
"ping" command and it looks like UEFI Shell cannot find the IPv4/IPv6 protocol 
handle. When I built a DEBUG release, I can see the network stack modules being 
loaded. So I do not understand why those protocol handles cannot be found.Is 
there a way to dump the handle database and check which protocols are 
instantiated ?

dh  will dump all the handles.
Thanx.

If your ethernet driver produces SNP, you need remove the EDKII SNP module.#

Subject: [edk2] 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,  #
