+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for gigabit Ethernet controller integrated in Marvell
+system-on-chip devices.
+.Pp
+The
+.Nm
+driver supports the following media types:
+.Pp
+.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
+.It autoselect
+Enable autoselection of the media type and options
+.It 10baseT/UTP
+Set 10Mbps operation
+.It 100baseTX
+Set 100Mbps operation
+.It 1000baseT
+Set 1000baseT operation
+.El
+.Pp
+The
+.Nm
+driver supports the following media options:
+.Pp
+.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
+.It full-duplex
+Set full duplex operation
+.El
+.Pp
+The
+.Nm
+driver supports polled operation when the system is configured with
+DEVICE_POLLING kernel option, see
+.Xr polling 4
+for more details.
+.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 .
+.Pp
+The
+.Nm
+driver supports interrupts coalescing (IC) so that raising a transmit/receive
+frame interrupt is delayed, if possible, until a threshold-defined period of
+time has elapsed. The following sysctls regulate this behaviour (separately
+for each path):
+.Bl -tag -width indent
+.It Va dev.mge.X.int_coal.rx_time
+.It Va dev.mge.X.int_coal.tx_time
+.Pp
+Value of 0 disables IC on the given path, value greater than zero corresponds
+to a real time period and is expressed in units equivalent to 64 ticks of the
+MGE clock. Maximum allowed value depends on MGE hardware revision. User
+provided values larger than supported will be trimmed to the maximum
+supported. More details are available in the reference manual of the device.
+.El
+.Sh HARDWARE
+Gigabit Ethernet controllers built into the following Marvell systems-on-chip
+are known to work with the
+.Nm
+driver:

+Discovery MV78100 (MGE V2)
+.El
+.Pp
+There are also Marvell system controllers for PowerPC processors, which
+include a variation of this gigabit Ethernet module integrated on chip, and
+they should also work with the
+.Nm

+.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 .

+.\"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.

+.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.
