       The  sn  driver  supports  the  SMC  91C90, SMC 91C92, SMC 91C94, SMC 91C95, SMC 91C96, SMC91C100 and SMC
       91C100FD chips from SMC.

       The Farallon EtherWave and EtherMac card came in two varieties.  The ep(4) driver supports  the  595  and
       895  cards.   These  cards  have  the  blue arrow on the front along with a 3Com logo.  The Farallon 595a
       cards, which have a red arrow on the front, are also called EtherWave and EtherMac.  They  are  supported
       by the sn driver.
