8 | * ChangeLog: | |
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 | |
14 | * from top-halves. | |
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. | |
