Subject: Linux de4x5 driver bug?

I am running UltraLinux 1.0.9 with kernel version 2.1.105 on a Sun Ultra 5.
The system contains a Znyx ZX346 4-port 10/100 ethernet card, which is
recognized by the de4x5 driver.

The first port of the card operates properly, but the other three ports either
fail to receive any packets, or exhibit extremely poor performance, with delays
of approximately 2 seconds just to receive a packet from the same ethernet.

Other minor problems which may be related are that "ifconfig -a" shows
incorrect values for various packet counters for any interface corresponding to
any Znyx ZX346 port, and that "netstat -i" reports "unknown interface" for any
interface.

The following messages are displayed on the console when doing a
modprobe de4x5 :
