Good spot.  I haven't look at the code and the impact of your patch
but it sounds like the undi driver is not written to support multiple
instances.  Hopefully this is an implementation detail in gPXE's UNDI
code rather than a limitation of UNDI.

Your patch looks like it works by overwriting undinet_entry_point for
the last opened NIC.  Does this allow for both NICs to be open and
used simultaneously?  Would the entry point need to be part of
undi_nic or undi_device in order to support true simultaneous
operation?
