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.
