PXE need to use extended DHCP options and check received offers in callback
function, so there is no need to continue the PXE process if DHCP driver has
been started by other instance but not PXE driver itself.

I guess this ASSERT can be removed since *NewPacket is checked later.

The PxeBcDhcp4CallBack() is provided for DHCP driver to invoke packet check
during DHCP process, the DHCP driver should make sure Packet and NewPacket
has meaningful value. This patch adds assert for this.

Hi Siyuan,
Some of these problems also exist in the MdeModulePkg/Universal/Network/UefiPxeBcDxe/. Is there a plan to fix them there as well, or will the MdeModulePkg copy of the drivers be removed sometime in the near future?
Thanks,
Sriram.
