+2004-02-16: <sda@xxxxxxx>
+- 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.
