[vortex-bug] 3c575_cb driver bug?

[davelee@mindspring.com]

here's my network adaptor:

Socket 1: Kernel/pcmcia-cs info:
  product info: "3Com Corporation", "3CCFE575BT", "LAN Cardbus Card",
"001"
Linux dlee.erisks.com 2.2.16-3 #1 Mon Jun 19 19:11:44 EDT 2000 i686
unknown
  manfid: 0x0101, 0x5157 PCMCIA-CS Version 3.1.8, as distributed in
kernel-pcmcia-cs-2.2.16-3.i386.rpm from RedHat 6.2
  function: 6 (network)


Symptom:

This is connected to a Linksys Firewall/Router BEFSR41 (4 port router).
The lights on the router indicate no full duplex.  However, when I
initiate a file transfer from the laptop to another machine on the
network, the full duplex light blinks intermittently, and I get poor (~
50k / sec) performance.

This card is full duplex, but as you can see from mii-diag, it is
advertising only half duplex:
