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"

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.
