got WORKING (at least in linux and windoze) network card, it has 10baseT
and 10base2 connectors, and i want to use 10base2

Jun  9 11:39:19 chylonia /netbsd: le0 at pci0 dev 10 function 0: PCnet-PCI Ethernet
Jun  9 11:39:19 chylonia /netbsd: le0: address 00:ff:ff:ff:ff:ff
Jun  9 11:39:19 chylonia /netbsd: le0: 8 receive buffers, 2 transmit
buffers
Jun  9 11:39:19 chylonia /netbsd: le0: interrupting at irq 9

and there are problems

a) MAC is for sure not 00:ff:ff:ff:ff:Ff
b) ifconfig media allows only 10baseT and 10base5, while i have 10baseT
and 10base2 and want 10base2
c) ifconfig media auto doesn't help. got only "device timeout" and "memory
error". no transmission
d) tried ifconfig 10base5 (thinking driver doesn't know that BNC
transceiver is on card). still doesn't work
