NAME
     ef - 3Com Fast EtherLink ISA (3c515) driver

SYNOPSIS
     ef* at isapnp?

DESCRIPTION
     The ef device driver supports the 3Com Fast EtherLink ISA family of Eth-
     ernet cards, and embedded controllers based on the 3Com ``corkscrew''
     EtherLink chips.  This includes the 3C515 adapter(s) with National Semi-
     conductor DP83840 PHYs, see nsphy(4). Other models of 3Com network cards
     are supported by the ec(4), eg(4), el(4), ep(4), ie(4) and xl(4) drivers.

     For more information on configuring this device, see ifconfig(8).

DIAGNOSTICS
     ef%d: adapter failure (%x)  A fatal error during receive or transmit has
     occurred.

     ef%d: eeprom failed to come ready  When reading/writing the EEPROM, the
     busy bit failed to clear.  This may indicate a hardware problem.

     ef%d: device timeout  The device has stopped responding to the network,
     or there is a problem with the network connection (cable).
