Multiple hamachi instances.

[G.W. Wettstein]

Good day to everyone who isn't in New York at Linux Expo or otherwise
travelling around the world.

We recently upgraded the kernels on our computational cluster.  All of
the machines are Gigabit ethernet attached using the GNIC-II Packet
Engine cards.  The kernel is 2.2.18 patches with Ingo's software raid.
The machines are dual PII-450's with 440BX motherboards, pretty
vanilla setup all in all.

The anomalous behavior we are noting is that the GNIC-II cards are
showing up 7 different times, all with identical statistics.  The
first instance is the configured interface and seems to function
fine.  When the driver is loaded as a module it presents only as a
single instance.  The following excerpt is the from the system probe
at boot time with a statically compiled kernel:

"One of the reporters asked if the could "see" the INTERNET worm.
They tried to explain that it wasn't something that you could actually
see but is was merely a program that was running in the background.
One of the reporters asked, 'What if you had a color monitor?'"
