DESCRIPTION

       ethtool  is  used  for  querying  settings  of  an  ethernet device and
       changing them.

       ethX is the name of the ethernet device to work on.

OPTIONS

       ethtool with a  single  argument  specifying  the  device  name  prints
       current setting of the specified device.

       -h     shows a short help message.

       -a     queries  the  specified  ethernet  device  for  pause  parameter
              information.

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

       autoneg on|off
              Specify if pause autonegotiation is enabled.

       rx on|off
              Specify if RX pause is enabled.

       tx on|off
              Specify if TX pause is enabled.

       -c     queries   the   specified   ethernet   device   for   coalescing
              information.

       -C     change the coalescing settings of the specified ethernet device.

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

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

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

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

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

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

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

       -d     retrieves  and prints a register dump for the specified ethernet
              device.  When raw is enabled, then it  dumps  the  raw  register
              data to stdout.

       -e     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
              certain portions of the EEPROM.  Default is to dump  the  entire
              EEPROM.

       -E     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     queries the specified ethernet device for offload information.

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

       rx on|off
              Specify if RX checksumming is enabled.

       tx on|off
              Specify if TX checksumming is enabled.

       sg on|off
              Specify if scatter-gather is enabled.

       tso on|off
              Specify if tcp segmentation offload is enabled.

       -p     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     restarts  auto-negotiation  on the specified ethernet device, if
              auto-negotiation is enabled.

       -S     queries the specified  ethernet  device  for  NIC-  and  driver-
              specific statistics.

       -t     executes  adapter  selftest  on  the  specified ethernet device.
              Possible 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     option  allows  changing  some  or all settings of the specified
              ethernet device.  All following options only  apply  if  -s  was
              specified.

       speed 10|100|1000
              Set  speed  in Mb/s.  ethtool with single argument will show you
              the supported device speeds.

       duplex half|full
              Set full or half duplex mode.

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

       autoneg on|off
              Specify if autonegotiation is enabled. In the usual case it  is,
              but  might cause some problems with some network devices, so you
              can turn it off.

       phyad N
              PHY address.

       xcvr internal|external
              Select 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...
              Set  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
              Set 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
              Set the driver message level. Meanings differ per driver.

BUGS

       Not  supported  (in  part  or  whole)  on  all  ethernet  drivers (read
       /usr/share/doc/ethtool/README.Debian to get  an  idea  about  supported
       features).

COMPATIBILITY

       Requires  2.4  or  newer  kernel  to  be effective.  Also work on Sparc
       running 2.2 kernel with Happy Meal ethernet card.
