Linux-2.6.12-rc2v2.6.12-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!

+ * Caution: this is experimental and probably buggy.  For success and
+ * failure reports for different cards and adaptors, see
+ * orinoco_tmd_pci_id_table near the end of the file.  If you have a
+ * card we don't have the PCI id for, and looks like it should work,
+ * drop me mail with the id and "it works"/"it doesn't work".
+ *
+ * Note: if everything gets detected fine but it doesn't actually send
+ * or receive packets, your first port of call should probably be to   
+ * try newer firmware in the card.  Especially if you're doing Ad-Hoc
+ * modes
+ *
+ * The actual driving is done by orinoco.c, this is just resource
+ * allocation stuff.
+ *
+ * This driver is modeled after the orinoco_plx driver. The main
+ * difference is that the TMD chip has only IO port ranges and no
+ * memory space, i.e.  no access to the CIS. Compared to the PLX chip,
+ * the io range functionalities are exchanged.
+ *
+ * Pheecom sells cards with the TMD chip as "ASIC version"
