EF(4) OpenBSD Programmer's Manual EF(4) NAME ef - 3Com Fast EtherLink ISA (3C515) 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). 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). SEE ALSO ec(4), eg(4), el(4), ep(4), ie(4), ifmedia(4), ifconfig(8) HISTORY The ef device driver first appeared in OpenBSD 2.6. AUTHOR The ef driver was written by Jason L. Wright <jason@thought.net>. BUGS The media handling assumes that there an external physical layer device (PHY), and that it will autonegotiate correctly. OpenBSD 2.7 August 3, 1999 1
