clean up previous sundance net driver fixes:

        - 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
