Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+ * 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.
