.Sh NAME
.Nm wx
.Nd Intel Gigabit Ethernet driver
.Sh SYNOPSIS
.Cd "wx* at pci? dev ? function ?"
.Sh DESCRIPTION
The
.Nm wx
driver provides support for Intel Gigabit Ethernet PCI cards based on the
.Tn i82452
chipset such as the Intel Pro/1000 Gigabit Server Adapter.
.Pp
The following media types and options (as given to
.Xr ifconfig 8 )
are supported:
.Pp
.Bl -tag -width XXX -offset indent
.It Cm media No 1000baseSX Cm mediaopt No full-duplex
Set 1000Mbps (Gigabit Ethernet) operation and force full-duplex mode.
.It Cm media No 1000baseSX
Set 1000Mpbs (Gigabit Ethernet) operation.
.El
.Pp
For more information on configuring this device, see
.Xr ifconfig 8 .
To view a list of media types and options supported by your card try
.Ic ifconfig -m <device> .
For example,
.Ic ifconfig -m wx0 .
.Sh DIAGNOSTICS
.Bl -diag
.It "wx%d: can't map registers"
A fatal initialization error has occurred.
.It "wx%d: couldn't map interrupt"
A fatal initialization error has occurred.
.It "wx%d: couldn't establish interrupt"
The device failed to allocate an interrupt (irq) line.
.It "wx%d: len (%lx) over a page for the receive ring"
The size of the receive ring is larger than the hardware page size.
.It "wx%d: could not allocate rcv descriptors"
The device failed to allocate memory for the receive descriptors.
.It "wx%d: rcv descriptors not 4KB aligned"
The memory management system returned memory for the receive descriptors
that was not aligned correctly.
.It "wx%d: len (%lx) over a page for the xmit ring"
The size of the transmit ring is larger than the hardware page size.
.It "wx%d: could not allocate xmt descriptors"
The device failed to allocate memory for the transmit descriptors.
.It "wx%d: xmt descriptors not 4KB aligned"
The memory management system returned memory for the transmit descriptors
that was not aligned correctly.
.It "wx%d: failed to do common attach (%d)"
The operating system independent section of the device driver
initialization failed.
.It "wx%d: link intr 0x%x"
The device has sensed a change in its link to the network.
.It "wx%d: packet with errors (%x)"
.It "wx%d: receive descriptor with no mbuf"
.It "wx%d: lost sync with partial packet"
.It "wx%d: null mbuf in gc"
.It ""
.It "wx%d: excess collisions"
The device has dropped a packet because too many collisions were seen
when trying to send it.
.It "wx%d: lost carrier"
The device has lost link integrity with the network, most likely a cabling
problem.
.It "wx%d: nactive < 0?"
.It "wx%d: swdpio did not clear"
.It ""
.It "wx%d: link never came up"
The device never saw the link to the network established.
.It "wx%d: device timeout"
The device has stopped responding to the network,
or there is a problem with the network connection (cable).
.It "wx%d: could not re-init device"
An error occured when trying to reset the device.
.It "wx%d: could not set up rbufs"

.Sh HISTORY
.Ox
support for the
.Nm
device driver first appeared in
