FreeBSD 7.0 manual page repository

FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

tx - SMC 83c17x Fast Ethernet device driver



      tx - SMC 83c17x Fast Ethernet device driver


      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):


      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
      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.


      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.
      arp(4), miibus(4), netintro(4), ng_ether(4), ifconfig(8)


      The auto-negotiation does not work very well.


Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
