Thank you for idea! I need only 8 ports :-) And it seems that cards like ASUS TX97 allow to do that. > Another issue I've had with the Adaptec cards 2143 based & Quad 10/100 > cards > is that I need to do a tcpdump on the interface to get the card to > work. > The scenario is > - ping to host (doesn't work) > - tcpdump -i <interface> > - the ping now starts to works. > I'm not sure about exactly that card, but in many cases switching the card to promiscuous mode required by tcpdump is made through reset.
