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