DESCRIPTION
       ethtool is used for querying settings of an ethernet device and  chang-
       ing them.

       ethX  is  the name of the ethernet device on which ethtool should oper-
       ate.

OPTIONS
       ethtool with a single argument specifying the device name  prints  cur-
       rent settings of the specified device.

       -h --help
              Shows a short help message.

       -a --show-pause
              Queries the specified ethernet device for pause parameter infor-
              mation.

       -A --pause
              Changes the pause parameters of the specified ethernet device.

       autoneg on|off
              Specifies whether pause autonegotiation should be enabled.

       rx on|off
              Specifies whether RX pause should be enabled.

       tx on|off
              Specifies whether TX pause should be enabled.

       -c --show-coalesce
              Queries the specified ethernet device  for  coalescing  informa-
              tion.

       -C --coalesce
              Changes  the  coalescing  settings  of  the  specified  ethernet
              device.

       -g --show-ring
              Queries the specified ethernet device for rx/tx  ring  parameter
              information.

       -G --set-ring
              Changes  the  rx/tx  ring  parameters  of the specified ethernet
              device.

       rx N   Changes the number of ring entries for the Rx ring.

       rx-mini N
              Changes the number of ring entries for the Rx Mini ring.

       rx-jumbo N
              Changes the number of ring entries for the Rx Jumbo ring.

       tx N   Changes the number of ring entries for the Tx ring.

       -i --driver
              Queries the specified  ethernet  device  for  associated  driver
              information.

       -d --register-dump
              Retrieves  and prints a register dump for the specified ethernet
              device.  The register format  for  some  devices  is  known  and
              decoded  others  are  printed in hex.  When raw is enabled, then
              ethtool dumps the raw register data to stdout.  If file is spec-
              ified,  then  use contents of previous raw register dump, rather
              than reading from the device.

       -e --eeprom-dump
              Retrieves and prints an EEPROM dump for the  specified  ethernet
              device.   When raw is enabled, then it dumps the raw EEPROM data
              to stdout. The length and offset parameters allow  dumping  cer-
              tain portions of the EEPROM.  Default is to dump the entire EEP-
              ROM.

       -E --change-eeprom
              Changes EEPROM byte for the specified ethernet  device.   offset
              and value specify which byte and it's new value.  Because of the
              persistent nature of writing to the  EEPROM,  a  device-specific
              magic key must be specified to prevent the accidental writing to
              the EEPROM.

       -k --show-offload
              Queries the specified ethernet device for offload information.

       -K --offload
              Changes the offload parameters of the specified ethernet device.

       rx on|off
              Specifies whether RX checksumming should be enabled.

       tx on|off
              Specifies whether TX checksumming should be enabled.

       sg on|off
              Specifies whether scatter-gather should be enabled.

       tso on|off
              Specifies whether TCP segmentation offload should be enabled.

       ufo on|off
              Specifies whether UDP fragmentation offload should be enabled

       gso on|off
              Specifies whether generic segmentation offload should be enabled

       -p --identify
              Initiates adapter-specific action intended to enable an operator
              to  easily  identify  the  adapter  by  sight.   Typically  this
              involves blinking one or more  LEDs  on  the  specific  ethernet
              port.

       N      Length of time to perform phys-id, in seconds.

       -r --negotiate
              Restarts  auto-negotiation  on the specified ethernet device, if
              auto-negotiation is enabled.

       -S --statistics
              Queries the specified ethernet device for NIC-  and  driver-spe-
              cific statistics.

       -t --test
              Executes adapter selftest on the specified ethernet device. Pos-
              sible test modes are:

       offline|online
              defines test type: offline (default) means to perform  full  set
              of  tests  possibly causing normal operation interruption during
              the tests, online means to perform limited set of tests  do  not
              interrupting normal adapter operation.

       -s --change
              Allows  changing  some or all settings of the specified ethernet
              device.  All following options only apply if -s was specified.

       speed 10|100|1000|2500
              Set speed in Mb/s.  ethtool with just  the  device  name  as  an
              argument will show you the supported device speeds.

       duplex half|full
              Sets full or half duplex mode.

       port tp|aui|bnc|mii
              Selects device port.

       autoneg on|off
              Specifies whether autonegotiation should be enabled. Autonegoti-
              ation is enabled by deafult, but in  some  network  devices  may
              have trouble with it, so you can disable it if really necessary.

       advertise N
              Sets the speed and duplex advertised  by  autonegotiation.   The
              argument  is  a  hexidecimal value using one or a combination of
              the following values:
              0x001    10 Half
              0x002    10 Full
              0x004    100 Half
              0x008    100 Full
              0x010    1000 Half(not supported by IEEE standards)
              0x020    1000 Full
              0x8000   2500 Full(not supported by IEEE standards)
              0x800    10000 Full
              0x03F    Auto

       phyad N
              PHY address.

       xcvr internal|external
              Selects transceiver type. Currently only internal  and  external
              can be specified, in the future further types might be added.

       wol p|u|m|b|a|g|s|d...
              Sets  Wake-on-LAN  options.   Not all devices support this.  The
              argument to this option is a  string  of  characters  specifying
              which options to enable.
              p  Wake on phy activity
              u  Wake on unicast messages
              m  Wake on multicast messages
              b  Wake on broadcast messages
              a  Wake on ARP
              g  Wake on MagicPacket(tm)
              s  Enable SecureOn(tm) password for MagicPacket(tm)
              d  Disable  (wake  on nothing).  This option clears all previous
                 options.

       sopass xx:yy:zz:aa:bb:cc
              Sets the SecureOn(tm) password.  The  argument  to  this  option
              must  be 6 bytes in ethernet MAC hex format (xx:yy:zz:aa:bb:cc).

       msglvl N
              Sets the driver message level. Meanings differ per driver.

BUGS
       Not supported (in part or whole) on all ethernet drivers.
