.Sh NAME
|
|
.Nm enic
|
|
.Nd eMIPS ExtensibleNIC Ethernet interface driver
|
|
.Cd "enic* at ebus0 addr ?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
interface provides access to a
|
|
.Tn Ethernet
|
|
network via the eMIPS builtin
|
|
.Tn eNIC
|
|
(Extensible Network Interface Controller - Ethernet) interface.
|
|
.Pp
|
|
Each of the host's network addresses
|
|
is specified at boot time with an
|
|
.Dv SIOCSIFADDR
|
|
.Xr ioctl 2 .
|
|
The
|
|
.Nm
|
|
interface employs the Address Resolution Protocol (ARP) described in
|
|
.Xr arp 4
|
|
to dynamically map between Internet and
|
|
.Tn Ethernet
|
|
addresses on the local network.
|
|
.Pp
|
|
Multicast Ethernet frames are unconditionally received and must be filtered in software.
|
|
.Sh HARDWARE
|
|
.Ss emips
|
|
The
|
|
.Tn ENIC
|
|
interface is present on the BEE3 and Xilinx XUP boards. The interface speed is wired at 1Gbps.
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "enic%d: enic_put: no mem?"
|
|
The driver could not allocate a transmit buffer, packet was not sent.
|
|
.It "enic%d: internal error"
|
|
This and other messages are indicative of bad hardware or software driver coding errors.
