check sum error

[Prof. Andreas Gerber]

While using a 3COM 905B: Manufacture date (MM/DD/YY) 7/21/99, division
6, product YW
I found the following message in /var/log/messages:
eth0: 3Com 3c905C Tornado at 0xb800,  ***INVALID CHECKSUM 002f*** 
00:50:da:09:30:79, IRQ 10 
8K byte-wide RAM 5:3 Rx:Tx split, autoselect/Autonegotiate interface.
   MII transceiver found at address 24, status 7809.
   Enabling bus-master transmits and whole-frame receives.


In principle the interface works but I observe very slow downloads from
the computer using samba and ftp.
It takes some minutes to get a file from the linux server to a win-nt
maschine. Transmitting a file from a NT computer to the linux pc yields
good performance (about 6000kb/s).

The linux box is operating under suse linux 6.2, kernel 2.2.10

Any hints/advices?

Thanks in advance

Andreas
