+/* orinoco_tmd.c 0.01
+ * 
+ * Driver for Prism II devices which would usually be driven by orinoco_cs,
+ * but are connected to the PCI bus by a TMD7160. 
+ *
+ * Copyright (C) 2003 Joerg Dorchain <joerg@dorchain.net>
+ * based heavily upon orinoco_plx.c Copyright (C) 2001 Daniel Barlow <dan@telent.net>

+
+ * 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"
