DESCRIPTION

     The gem driver provides support for the GMac Ethernet hardware found
     mostly in the last Apple PowerBooks G3s and most G4-based Apple hardware,
     as well as many Sun UltraSPARCs.

     Cards supported by this driver include:
           ·   Sun GEM gigabit ethernet
           ·   Sun ERI 10/100
           ·   Apple GMAC

     The GEM family supports hardware checksumming to assist in computing IPv4
     TCP/UDP checksums.  The gem driver supports this feature of the chip.
     See ifconfig(8) for information on how to enable this feature.
