5 * it under the terms of the GNU General Public License version 2 as
6 * published by the Free Software Foundation.
9 * .... Most of the time spent on reading sources & docs.
10 * v0.2.x First official release for the Linux kernel.
11 * v0.3.0 Beutified and structured, some bugs fixed.
12 * v0.3.x URBifying bulk requests and bugfixing. First relatively
13 * stable release. Still can touch device's registers only
15 * v0.4.0 Control messages remained unurbified are now URBs.
16 * Now we can touch the HW at any time.
17 * v0.4.9 Control urbs again use process context to wait. Argh...
18 * Some long standing bugs (enable_net_traffic) fixed.
19 * Also nasty trick about resubmiting control urb from
20 * interrupt context used. Please let me know how it
21 * behaves. Pegasus II support added since this version.
22 * TODO: suppressing HCD warnings spewage on disconnect.
23 * v0.4.13 Ethernet address is now set at probe(), not at open()
24 * time as this seems to break dhcpd.
25 * v0.5.0 branch to 2.5.x kernels
26 * v0.5.1 ethtool support added
27 * v0.5.5 rx socket buffers are in a pool and the their allocation
28 * is out of the interrupt routine.
