Does uefi dhcp client requires any specific dhcp request parameters in
DHCPREQUEST message?
And should dhcp server be configured to offer any specific parameters in
DHCPOFFER message in case of uefi dhcp client?

Yes.
I was just testing that if I am be set ip(dhcp) thrpugh uefi shell, as the same
will be happening during uefi pxe boot as in uefi pxe boot uefi network stack
is used(dhcp, ifconfig, mtftp).
So, in my case I am not able to configure ip through uefi shell itself, so uefi
pxe boot will also fail.
Why do you think that? Do you mean the OS Loader that has been booted will
fail? A PXE boot of the EFI image requires zero configuration. The DHCP ext
tags from the PXE server provide the client with all the need configuration
information needed to boot. The PXE server can also match the client GUID/UUID
and serve a specific boot image to that client. The only configuration in all
of this is on the PXE server side.
The PXE boot and manual config are different paths.

That's why I trying to find if there is any issue with network card uefi driver
or with uefi network stack.

Hi,
I am facing problem in configuring ip through uefi shell. (main purpose is to
do uefi pxe boot on rhel6.5 pxe server)
You don't need to configure an ip to PXE boot?
When you PXE boot there are DHCP requests that get made that are returned by
the PXE sever that tell you where to boot from. No config is required on the
EFI side. If the PXE boot does not work it is like an issue with the config of
the PXE server.

First I tried to configure ip (dhcp) from uefi shell, which is giving attached
logs on dhcp sever, IP is not configured.
Using command:
Shell>Ifconfig -s eth5 dhcp
After this, it doesn't get ip.

And
I configured IP on the same server which is running rhel (rhel6.5 OS netwotk
stack), this means there is no issue in dhcp server setup.
How can I find out if issue is with uefi network stack or network card uefi
driver? as network card legacy driver works fine.
