Revert r336773: it removed too much.

Browse Source 
r336773 removed all things xscale. However, some things xscale are
really armv5. Revert that entirely. A more modest removal will follow.

.Dt NPE 4 arm
.Os
.Sh NAME
.Nm npe
.Nd "Intel XScale Network Processing Engine (NPE) Ethernet device driver"
.Sh SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device npe"
.Cd "device npe_fw"
.Cd "device firmware"
.Cd "device qmgr"
.Cd "device miibus"
.Ed
.Sh DESCRIPTION
The
.Nm
driver provides support for Ethernet adapters based on the Intel
XScale Network Processing Engine (NPE).
The NPE must be loaded with firmware that is typically distributed
with boards that have this part.
Otherwise the firmware may be obtained at no cost from the Intel web site.
.Pp
The
.Nm
driver supports the following media types:
.Bl -tag -width ".Cm full-duplex"
.It Cm autoselect
Enable autoselection of the media type and options.
.It Cm 10baseT/UTP
Set 10Mbps operation.
.It Cm 100baseTX
Set 100Mbps (Fast Ethernet) operation.
.El
.Pp
The
.Nm
driver supports the following media options:
.Bl -tag -width ".Cm full-duplex"
.It Cm full-duplex
Set full duplex operation.
.El
.Pp
The
.Nm
driver supports polled operation when the system is
configured with device polling support,
.Xr polling 4 .
Note that for multi-port configurations polling and interrupt-style
operation should not be combined as one of the hardware queues
is shared by all ports.
.Pp
For further information on configuring this device, see
.Xr ifconfig 8 .
.\".Pp
.\"The
.\".Nm
.\"driver supports reception and transmission of extended frames
.\"for
.\".Xr vlan 4 .
.\"This capability of
.\".Nm
.\"can be controlled by means of the
.\".Cm vlanmtu
.\"parameter
.\"to
.\".Xr ifconfig 8 .
.Sh HARDWARE
The adapters supported by the
.Nm
driver exist only on boards that have an XScale processor.
.Sh DIAGNOSTICS
.Bl -diag
.It "npe%d: unit %d not supported"
The unit is larger than the maximum number built into the driver.
This should not happen as
.Nm
devices are not really probed for; they are statically enumerated.
.It "npe%d: Cannot find my PHY."
The associated PHY did not appear while probing the MII bus.
The relationship between PHYs and NPEs is statically defined
in the driver and may require alterations to the driver for new boards.
.It "npe%d: unable to allocate memory for %s ... buffers"
There is not enough memory available for allocation.
The driver pre-allocated memory during attach so this should not happen.
.It "npe%d: remember to fix rx q setup"
See
.Sx BUGS
below.
.It "npe%d: free mbuf at entry %u"
An mbuf was unexpectedly found on the device queue; the index of
the queue entry is printed.
.It "npe%d: too many fragments %u"
A frame was dropped on transmit because it was too fragmented and
the logic to de-fragment failed.
This should not happen.
.It "npe%d: device timeout"
The device has stopped responding to the network, or there is a problem with
the network connection (cable).
.El
.Pp
Other diagnostics exist and are not listed here;
they should be self-explanatory.
.Sh SEE ALSO
.Xr altq 4 ,
.Xr arp 4 ,
.Xr miibus 4 ,
.Xr netintro 4 ,
.Xr polling 4 ,
.Xr qmgr 4 ,
.\".Xr vlan 4 ,
.Xr ifconfig 8
.Sh HISTORY
The
.Nm
device driver first appeared in
.Fx 6.3 .
.Sh CAVEATS
This driver has been tested only with dual-port boards using the IXP425
such as the Gateworks Avila 2348.
Some changes to the driver may be required for other configurations.
.Sh BUGS
The hardware queues are not properly flushed when the interface
is marked down.
.Pp
The assignment of receive traffic classes to hardware queues
is presently incomplete.
Only the first 4 classes are assigned while there are 8 total.
The driver will print
.Dq Li "remember to fix rx q setup"
on startup as a reminder.
For the moment it is not a problem as all traffic arrives classified
with class 0.

* BUG ALERT! \
* \
* The XScale core has a strange cache eviction bug, which \
* requires us to use 2x the cache size for the cache clean \
* and for that area to be aligned to 2 * cache size. \
* \
* The work-around is to use 2 areas for cache clean, and to \
* alternate between them whenever this is done. No one knows \
* why the work-around works (mmm!). \
