Thanks, Michael,
After updating to the latest iPXE (which seems to include this change),
everything works fine with my USB-NIC.
I think the change should work for my USB-NIC. Thanks very much for your
great help!
Regards,
Jerry

It's possible that your card is erroneously reporting that it doesn't
support interrupts, when in fact it requires the interrupt-triggered call
to PXENV_UNDI_ISR_IN_START in order to make packet reception work. You
could try overriding the interrupts-supported detection logic using the
attached patch.
I have committed a change that should (hopefully) fix this problem
permanently:

I think this should solve your interrupt-related problem, without breaking
the
Emulex NICs.
