not actually used yet. This created a lot of prototypes.
I moved code around so that the functions are in the same order as NetBSD - this helps diff a lot.
Things that are missing are the TX routine and ifmedia stuff and ioctls
Not all of the stuff is enabled - we are missing calls in ccs_done and ioctl.
Promiscious mode is working.
Am almost ready to use the NetBSD start up routine - essentially all I need
to do is not use a seperate timer to call download_timo.
Other misc. things:
callout_stop is a newish feature for cancelling a timer without
argument checking it.
tried to add a sysctl knob but it doesn't work in the module
enabled infrastructure code to call netbsd bits.
