The register definitions in tests/qtest/e1000e-test.c had names
different from hw/net/e1000_regs.h, which made it hard to understand
what test codes corresponds to the implementation. Use
hw/net/e1000_regs.h from tests/qtest/libqos/e1000e.c to remove
these duplications.

  Hi!

Thank you for your patches! Just a very small nit: That "libqos/malloc.h" 
was still old context, the file is called "libqos/libqos-malloc.h" now - 
please make sure to send patches based on the latest git master branch. 
Anyway, it was trivial to fix up, so I've queued your patch now (together 
with your three other patches) to my testing-next branch:

  https://gitlab.com/thuth/qemu/-/commits/testing-next
