[PATCH] 2.6.3 orinoco.c patch to support ethtool get_link

[Thomas Munck Steenholdt <tmus@xxxxxxx>]

Hi there!

I noticed that there wasn't a good way, from userland, to get the link
status of an orinoco device. So I implemented the basic stuff required
to support ethtool. then I implemented the get_link functionality of
ethtool (maps orinoco_private->connected the the ethtool link state). It
seems to work and will save people some boot-time (on the distros that
check for link before attempting DHCP configuration etc.) when laptop
users are not on there wireless location.

Also it lays the ground to move more functionality to the ethtool model.

Please let me know what you think!

Best regards

Thomas
