Please include the driver version number, along with the rest of the
driver detection message.

Unless you downloaded and compiled it yourself, the "2.4.18" kernel you
are running has likely been modified by the distribution vendor.  That
might include a driver version change.

Try a newer version
  mkdir /tmp/netdrivers/
  cd /tmp/netdrivers/
  ncftp ftp://ftp.scyld.com/pub/network/netdrivers.tgz
  tar xfvz netdrivers.tgz
  make
  make install

Transmitter is idle, Rx is waiting for packets.  There is no obvious
problem.

Errrkkk??  Setting CSR6 to 44000?
You should really try the driver from scyld.com

Likely unrelated:
That's a curious setting for the PCI parameters.  That might be what
caused the Tx threshold to increase.
