NAME

       tx — SMC 83c17x Fast Ethernet device driver

SYNOPSIS

       To compile this driver into the kernel, place the following lines in your kernel configuration file:

             device miibus
             device tx

       Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

             if_tx_load="YES"

DEPRECATION NOTICE

       The      tx     driver     is     not     present     in     FreeBSD     13.0     and     later.      See
       https://github.com/freebsd/fcp/blob/master/fcp-0101.md for more information.

DESCRIPTION

       The tx driver provides support for the Ethernet adapters based on the SMC 83c17x (EPIC) chips.  These are
       mostly SMC 9432 series cards.

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

       autoselect   Enable autonegotiation (default).

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

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

       10baseT/UTP  Set 10Mbps on 10baseT port.

       10base2/BNC  Set 10Mbps on 10base2 port.

       The tx driver supports the following media options:

       full-duplex  Set full-duplex operation.

       The tx driver supports oversized Ethernet packets (up to 1600 bytes).  Refer to the ifconfig(8) man  page
       on setting the interface's MTU.

       The old “ifconfig tx0 linkN” method of configuration is not supported.

   VLAN (IEEE 802.1Q) support
       The  tx  driver  supports the VLAN operation (using vlan(4) interfaces) without decreasing the MTU on the
       vlan(4) interfaces.

DIAGNOSTICS

       tx%d: device timeout %d packets  The device stops responding.   Device  and  driver  reset  follows  this
       error.

       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.

       tx%d: cannot allocate mbuf header/cluster  Cannot allocate memory for  received  packet.   Packet  thrown
       away.

       tx%d: can't stop %s DMA  While resetting, the driver failed to stop the device correctly.

BUGS

       The auto-negotiation does not work very well.
