MX987xx NIC driver support

Glad to hear from you. I have several of your adapters and I am quite
pleased with their performance in windows 95, however, the Linux support
is severely lacking.

Currently, people seem to be using the driver for the DEC Tulip 2X41X
cards. While this *works* in the strickest sense of the word, performance
is not good, packet duplications are common, and it is impossible for the
driver to work in any media mode except 10base half-duplex. 

The problem seems not to be with the register compatibility with the DEC
2141x, but rather with the fact that many cards with the MX chipsets do
not have full EEPROM tables. It is possible for the driver to include
vendor/chip specific programming for each card, and this has been done for
some other cards based on 2141x clones, etc.

The maintainer of the Linux 2141x driver is Donald Becker, a research
scientist at NASA. In addition to the Tulip driver, he has written many
other drivers for a myriad of Linux ethernet interfaces and is very highly
respected in the Linux community. I am not sure what his role is in
programming vendor-specific EEPROM information that would help to make the
MX cards more compatible, but you can certainly talk to him. His email
address is:
Again, thank you for your interest in the support of your chipset. There
are alot of ethernet vendors out there who are commited to not making
their programming information public for Linux support. I am sure that you
will see that working together with the Linux community will be the
fastest way to getting your products best supported and will benefit both
Linux users and your company.
