Possible test modes are:offline|onlinedefines 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.-soption allows changing some or all settings of the specified ethernet device. All following options only apply if -s was specified.speed 10|100|1000Set speed in Mb/s. ethtool with single argument will show you the supported device speeds.duplex half|fullSet full or half duplex mode.port tp|aui|bnc|miiSelect device port.autoneg on|offSpecify 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.phyadNPHY address.xcvr internal|externalSelect 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.pWake on phy activityuWake on unicast messagesmWake on multicast messagesbWake on broadcast messagesaWake on ARPgWake on MagicPacket(tm)sEnable SecureOn(tm) password for MagicPacket(tm)dDisable (wake on nothing). This option clears all previous options.sopass xx:yy:zz:aa:bb:ccSet the SecureOn(tm) password. The argument to this option must be 6 bytes in ethernet MAC hex format (xx:yy:zz:aa:bb:cc).msglvlNSet the driver message level. Meanings differ per driver
