RX packet errors problem

Wed Mar 22 19:25:18 2000

Hi, I'm having some ethernet problems with my Linux box.  I've been
searching the net for a few weeks but can't seem to find anything
relevant.  I'm hoping that if no one on this list can help me, then at
least someone will be able to point me in the right direction.

My problem is this: my eth0 interface gives me lots (up to 1%) of RX 
packet errors.  The card is a 3c590 10Mbit PCI adapter in a 200MHz PPro
computer with 128 MB RAM.  Sorry, I don't know the motherboard maker.  The
computer dual boots WinNT 4.0 and Caldera OpenLinux 2.3.  I've upgraded to
the latest (0.99L) Vortex driver.  I never notice any network problems in
WindowsNT, and web browsing seems to be much more responsive than in
Linux, so I'm suspecting a software problem.  Looking through pages and
pages on the web, it doesn't seem normal to even have ANY RX packet
errors, judging by the statistics people post when they have other
problems.  That is why I'm suspecting my sluggish network performance in
Linux is due to these packet errors.

The output of ifconfig and dmesg are given below.  Thanks in advance for
any help you can give me.
