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) interface.

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 filtered 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.
