ax88790 chipset 100mbit/s support

[dvc at jtxa.de]

hello,

i have a 10/100 fast ethernet pccard labeled "sitecom".
it is built around the asix ax88790 chipset and runs 
at 10 mbit using the ed driver.

is 10 mbit/sec the maximum transfer rate the ed driver 
supports? 

does somebody know a way i can use this card at 100
mbit/sec on my freebsd-5.3-release system?

the dmesg output for ed0:

ed0: <PCMCIA FastEthernet> at port 0x300-0x31f irq 5 
function 0 config 7 on pccard1
ed0: [GIANT-LOCKED]
