DESCRIPTION
     The le interface provides access to the 10 Mb/s Ethernet network via the
     AMD 7990 LANCE Ethernet chip set.

HARDWARE
     The le interface supports the following mvme68k hardware:

           onboard  MVME147 onboard Ethernet interface

           MVME376  MVME376 VMEbus Ethernet card

HARDWARE CONFIGURATION
     For MVME376, the card's base address (matching the addr locator on the
     configuration line) is defined through three sets of DIP switches,
     ``SW1'' and ``SW2'', located in the middle of the board, near the space
     between the two VME connectors, and ``SW3'', closer to the AM7990DC chip
     at the bottom edge.

     The only supported configurations are:

     SW1         SW2         SW3         Address

     UUU_UU_U    U__U____    ______U_    0xffff1200
     UUU_U_UU    U__U_U__    ______U_    0xffff1400
     UUU_U__U    U__UU___    ______U_    0xffff1600
     U_U_U_UU    U__UUU__    ______U_    0xffff5400
     U_U_U__U    U_U_____    ______U_    0xffff5600
     _U_UU_UU    U_U__U__    ______U_    0xffffa400

HISTORY
     The mvme68k le interface first appeared in OpenBSD 2.0.
