netgear 310TXrevD1+ 100 hub - very slow

[Dmitry Veprintsev]

Hi. 
I am in the process of upgrading the network to 100mb, and installed
NetGear 310TX-rev D1 on P75 with 16M ram, kernel 2.2.3 with either 0.89 or
0.91 version of tulip.c 
the card works fine, if connected to 10mbs HUB, but if i connect it to
100/10 DS hub (or directly to the switch), then access from 10mbs laptop is
extrememly slow. The lights on card and HUB report 100 (this is netgear
DS104). 
any suggestions? thanks in advance
