+.Sh NAME
+.Nm gx
+.Nd "Intel Pro/1000 gigabit ethernet driver"
+.Sh SYNOPSIS
+.Cd "gx* at pci? device ? function ?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for NICs based on the Intel 82542, 82543 and
+82544 gigabit ethernet controller chips.
+Both fiber and copper variants of
+the cards are supported.
+The following cards are supported:
+.Pp
+.Bl -bullet -compact
+.It
+Intel i82542 1000BASE-X Ethernet
+.It
+Intel i82543 1000BASE-X Ethernet
+.It
+Intel i82543-SC 1000BASE-X Ethernet
+.It
+Intel i82543 1000BASE-T Ethernet
+.It
+Intel i82544 1000BASE-T Ethernet
+.It
+Intel i82544 1000BASE-X Ethernet
+.It
+Intel i82544GC 1000BASE-T Ethernet (32- and 64-bit)
+.El
+.Pp
+The 82542 supports TBI (ten bit interface), while the 82543 and 82544
+support the GMII transceivers, which means they can be used with either
+copper or 1000baseX fiber applications.
+.\" Both boards support VLAN tagging/insertion and the 82543 and 82544
+.\" additionally support TCP/IP checksum offload.
+.Pp
+The 82543 and 82544 copper cards use the Marvell 10/100/1000 copper
+gigabit transceiver chip, which supports autonegotiation of 10, 100
+and 1000mbps modes in full or half duplex, however half duplex
+1000mbps is not supported.
+.Pp
+The
+.Nm
+driver supports the following media types:
+.Bl -tag -width ".Cm 10baseT"
+.It Cm autoselect
+Enable autoselection of the media type and options.
+User can manually override
+the autoselected mode by adding media options to
+.Xr rc.conf 5 .
+.It Cm 10baseT
+Set 10Mbps operation.
+The
+.Xr ifconfig 8 Ns 's
+.Cm mediaopt
+option can also be used to select either
+.Cm full-duplex
+or
+.Cm half-duplex
+modes.
+.It Cm 100baseTX
+Set 100Mbps (fast ethernet) operation.
+The
+.Xr ifconfig 8 Ns 's
+.Cm mediaopt
+option can also be used to select either
+.Cm full-duplex
+or
+.Cm half-duplex
+modes.
+.It Cm 1000baseTX
+Set 1000baseTX operation over twisted pair.
+Only
+.Cm full-duplex
+mode is supported.
+.El
+.Pp
+The
+.Nm
+driver supports the following media options:
+.Bl -tag -width ".Cm full-duplex"
+.It Cm full-duplex
+Force full duplex operation.
+.It Cm half-duplex
+Force half duplex operation.
+.El
+.Pp
+The
+.Nm
+driver also supports one special link option for 1000baseTX cards:
+.Bl -tag -width ".Cm link0"
+.It Cm link0
+With 1000baseTX cards, establishing a link between two ports requires
+that one port be configured as a master and the other a slave.
+With autonegotiation,
+the master/slave settings should be chosen automatically.
+Setting the
+.Cm link0
+flag with
+.Xr ifconfig 8
+will force the link up instead.
+.El
+.Pp
+For more information on configuring this device, see
+.Xr ifconfig 8 .
+.Sh DIAGNOSTICS
+.Bl -diag
+.It "gx%d: couldn't map memory"
+A fatal initialization error has occurred.
+.It "gx%d: couldn't map interrupt"
+A fatal initialization error has occurred.
+.It "gx%d: couldn't setup irq"
+A fatal initialization error has occurred.
+.It "gx%d: failed to read station address"
+A fatal initialization error has occurred.
+.It "gx%d: no memory for list buffers!"
+The driver failed to allocate memory for per-device instance information
+during initialization.
+.It "gx%d: failed to enable memory mapping!"
+The driver failed to initialize PCI shared memory mapping.
+This might happen if the card is not in a bus-master slot.
+.It "gx%d: GMII/MII, PHY not detected"
+The MII probe routines failed to detect the PHY.
+This might happen if miibus is not configured.
+.It "gx%d: watchdog timeout"
+The device has stopped responding to the network, or there is a problem with
+the network connection (cable).
+.It "gx%d: mbuf allocation failed -- packet dropped"
+The driver could not allocate a mbuf for the receive ring.
+.It "gx%d: cluster allocation failed -- packet dropped"
+The driver could not allocate a mbuf cluster for the receive ring.
+.It "gx%d: link down"
+The link status changed from up to down.
+.It "gx%d: link up"
+The link status changed from down to up.

+The
+.Nm
+device driver first appeared in
+.Ox 3.1 .
