jul/09/2002 : only implement two kind of dongle currently.
Oct/02/2002 : work on VT8231 and VT8233 .
Aug/06/2003 : change driver format to pci driver .
-
-2004-02-16: <sda@bdit.de>
-- Removed unneeded 'legacy' pci stuff.
-- Make sure SIR mode is set (hw_init()) before calling mode-dependant stuff.
-- On speed change from core, don't send SIR frame with new speed.
- Use current speed and change speeds later.
-- Make module-param dongle_id actually work.
-- New dongle_id 17 (0x11): TDFS4500. Single-ended SIR only.
- Tested with home-grown PCB on EPIA boards.
-- Code cleanup.
