- Autodetect where mii_preable_required is needed,
default to not needed. (Donald Becker)

+ Version LK1.04b:
+ - Remove mii_preamble_required module parameter (Donald Becker)
+ - Add per-interface mii_preamble_required (setting is autodetected)
+ (Donald Becker)
+ - Remove unnecessary cast from void pointer
+ - Re-align comments in private struct
