Are there any way to detect if the NIC is currently working ?
On SUN station, they send loopback packets to detect, does
the Linux/3c59x has similar methord?
I used Linux as a firewall in my company, and sometimes( about
1or2 for 2 months) the 3c906B stop working and print error messages,
or the HUB line disconnected by someone else.
I want linux to detect and alert me if it can't forwarding pkts!!
