We use our own, see

If you are using external Ethernet chips such as the SMSC 91Cxxx
series, RealTek 8019AS (and other NE2000 clones) or Asix 88976,
the drivers are pretty simple and there are plenty of code
examples on the net. Once you know what you are doing, about 200
lines of code.
The Ethernet controllers integrated into most CPUs tend to
consist of a MAC unit with small buffers and a DMA engine. You
have to manage it all yourself. They can require 1000+ lines of
code.
What to do depends on the hardware volume and how much time you
have.
