 *	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.
