- * 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.
