ENIC(4)                 NetBSD Kernel Interfaces Manual                ENIC(4)


NAME

     enic -- eMIPS ExtensibleNIC Ethernet interface driver


SYNOPSIS

     enic* at ebus0 addr ?


DESCRIPTION

     The enic interface provides access to an Ethernet network via the eMIPS
     builtin eNIC (Extensible Network Interface Controller - Ethernet) inter-
     face.

     Each of the host's network addresses is specified at boot time with an
     SIOCSIFADDR ioctl(2).  The enic interface employs the Address Resolution
     Protocol (ARP) described in arp(4) to dynamically map between Internet
     and Ethernet addresses on the local network.

     Multicast Ethernet frames are unconditionally received and must be fil-
     tered in software.


HARDWARE

   emips
     The ENIC interface is present on the BEE3 and Xilinx XUP boards.  The
     interface speed is wired at 1Gbps.


DIAGNOSTICS

     enic%d: enic_put: no mem?  The driver could not allocate a transmit
     buffer, packet was not sent.

     enic%d: internal error  This and other messages are indicative of bad
     hardware or software driver coding errors.
