370 . A description of the SMSC registers is probably in order here,

373 . Basically, the chip has 4 banks of registers ( 0 to 3 ), which
374 . are accessed by writing a number into the BANK_SELECT register
375 . ( I also use a SMC_SELECT_BANK macro for this ).
377 . The banks are configured so that for most purposes, bank 2 is all
