-.Dt TX 4

-.Os

-.Sh NAME

-.Nm tx

-.Nd "SMC 83c17x Fast 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 miibus"

-.Cd "device tx"

-.Ed

-.Pp

-Alternatively, to load the driver as a

-module at boot time, place the following line in

-.Xr loader.conf 5 :

-.Bd -literal -offset indent

-if_tx_load="YES"

-.Ed

-.Sh DEPRECATION NOTICE

-The

-.Nm

-driver is not present in

-.Fx 13.0

-and later.

-See https://github.com/freebsd/fcp/blob/master/fcp-0101.md for more

-information.

-.Sh DESCRIPTION

-The

-.Nm

-driver provides support for the Ethernet adapters based on the

-SMC 83c17x (EPIC) chips.

-These are mostly SMC 9432 series cards.

-.Pp

-The

-.Nm

-driver supports the following media types (depending on card's capabilities):

-.Bl -tag -width ".Cm 10baseT/UTP"

-.It Cm autoselect

-Enable autonegotiation (default).

-.It Cm 100baseFX

-Set 100Mbps (Fast Ethernet) fiber optic operation.

-.It Cm 100baseTX

-Set 100Mbps (Fast Ethernet) twisted pair operation.

-.It Cm 10baseT/UTP

-Set 10Mbps on 10baseT port.

-.It Cm 10base2/BNC

-Set 10Mbps on 10base2 port.

-.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 oversized Ethernet packets (up to 1600 bytes).

-Refer to the

-.Xr ifconfig 8

-man page on setting the interface's MTU.

-.Pp

-The old

-.Dq Li "ifconfig tx0 linkN"

-method of configuration is not supported.

-.Ss "VLAN (IEEE 802.1Q) support"

-The

-.Nm

-driver supports the VLAN operation (using

-.Xr vlan 4

-interfaces) without decreasing the MTU on the

-.Xr vlan 4

-interfaces.

-.Sh DIAGNOSTICS

-.Bl -diag

-.It "tx%d: device timeout %d packets"

-The device stops responding.

-Device and driver reset follows this error.

-.It "tx%d: PCI fatal error occurred (%s)"

-One of following errors occurred: PCI Target Abort, PCI Master Abort, Data

-Parity Error or Address Parity Error.

-Device and driver reset follows this error.

-.It "tx%d: cannot allocate mbuf header/cluster"

-Cannot allocate memory for received packet.

-Packet thrown away.

-.It "tx%d: can't stop %s DMA"

-While resetting, the driver failed to stop the device correctly.

-.El

-.Sh SEE ALSO

-.Xr arp 4 ,

-.Xr miibus 4 ,

-.Xr netintro 4 ,

-.Xr ng_ether 4 ,

-.Xr ifconfig 8

-.Sh BUGS

-The auto-negotiation does not work very well.
