Debugging shows that execution is trapped in an infinite loop that is somehow trying to reconnect drivers (without going via ConnectController()). The problem can be reproduced in the UEFI shell with no iPXE code present, by using the "disconnect" command. Experimentation shows that the only fix is to unload (rather than just disconnect) the "Ip4ConfigDxe" driver. Add the concept of a blacklist of UEFI drivers that will be automatically unloaded when iPXE runs as an application, and add the Dell Ip4ConfigDxe driver to this blacklist.
