.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
device driver provides support for the Altera Triple-Speed Ethernet
|
|
MegaCore.
|
|
.Sh HARDWARE
|
|
The current version of the
|
|
.Nm
|
|
driver supports the Ethernet MegaCore as described in version 11.1 of
|
|
Altera's documentation when the device is configured with internal FIFOs.
|
|
.Sh MAC SELECTION
|
|
The default MAC address for each
|
|
.Nm
|
|
interface is derived from a value stored in
|
|
.Xr cfi 4
|
|
flash.
|
|
The value is managed by the
|
|
.Xr atsectl 8
|
|
utility.
|
|
.Pp
|
|
Only a single MAC address may be stored in flash.
|
|
If the address begins with the Altera prefix 00:07:ed and ends in 00 then
|
|
up to 16 addresses will be derived from it by adding the unit number of
|
|
the interface to the stored address.
|
|
For other prefixes, the address will be assigned to atse0 and random
|
|
addresses will be used for other interfaces.
|
|
If the stored address is invalid, for example all zero's, multicast, or the
|
|
default address shipped on all DE4 boards (00:07:ed:ff:ed:15) then a random
|
|
address is generated when the device is attached.

|
|
.Sh BUGS
|
|
The
|
|
.Nm
|
|
driver only supports a single configuration of the MegaCore as installed
|
|
on the Terasic Technologies Altera DE4 Development and Education Board.
|
|
.Pp
|
|
Only gigabit Ethernet speeds are currently supported.
