Run either
Code:
~> /usr/sbin/ethtool eth0

or
Code:
/usr/sbin> ./ethtool eth0

If neither works, try logging in as root and running it, or run it via su/sudo

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.

       -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.
	      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.
