+===== 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.
+<a name''"lbAE" />
+===== 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.
+   $**-e**  : retrieves and prints an EEPROM dump for the specified ethernet device.
+   $**-k**  : queries the specified ethernet device for checksumming information.
+   $**-K**  : change the checksumming 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.
+   $**-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.
+      $ <br />:
+         $**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.
