I have some experience with this combination of controller.  The company I
work for makes a (Linux-based) product with three of them onboard.
Specifically, custom controllers based on the 21143-TB and TD with QSI6611
MII-less PHY.

This is correct; if your controller is just like mine, your SROM is
programmed with 4 infoblocks; two each for 10Mb SIA media and 100base-TX
SYM media.  The QS6611 does not support MII.

Donald Becker's latest tulip.c driver from should drive your
controller at 10 and 100Mb/s.  However, we had two specific problems with
the tulip.c driver: first, the 10Mb/s link LED and the activity LED did not
operate properly (the CSR15 general purpose control and data information
from the SROM infoblocks was not being used), and the media detection did
not work properly.  I'd like to know how it works for you.
