* ChangeLog:
* .... Most of the time spent on reading sources & docs.
* v0.2.x First official release for the Linux kernel.
* v0.3.0 Beutified and structured, some bugs fixed.
* v0.3.x URBifying bulk requests and bugfixing. First relatively
* stable release. Still can touch device's registers only
* from top-halves.
* v0.4.0 Control messages remained unurbified are now URBs.
* Now we can touch the HW at any time.
* v0.4.9 Control urbs again use process context to wait. Argh...
* Some long standing bugs (enable_net_traffic) fixed.
* Also nasty trick about resubmiting control urb from
* interrupt context used. Please let me know how it
* behaves. Pegasus II support added since this version.
* TODO: suppressing HCD warnings spewage on disconnect.
* v0.4.13 Ethernet address is now set at probe(), not at open()
* time as this seems to break dhcpd.
* v0.5.0 branch to 2.5.x kernels
* v0.5.1 ethtool support added
* v0.5.5 rx socket buffers are in a pool and the their allocation
* is out of the interrupt routine.
* ...
* v0.9.3 simplified [get|set]_register(s), async update registers
* logic revisited, receive skb_pool removed.
