Amit Cohen ecc31c6024 ethtool: Add link extended state 
Currently, drivers can only tell whether the link is up/down using
LINKSTATE_GET, but no additional information is given.

Add attributes to LINKSTATE_GET command in order to allow drivers
to expose the user more information in addition to link state to ease
the debug process, for example, reason for link down state.

Extended state consists of two attributes - link_ext_state and
link_ext_substate. The idea is to avoid 'vendor specific' states in order
to prevent drivers to use specific link_ext_state that can be in the future
common link_ext_state.

The substates allows drivers to add more information to the common
link_ext_state. For example, vendor can expose 'Autoneg' as link_ext_state
and add 'No partner detected during force mode' as link_ext_substate.

If a driver cannot pinpoint the extended state with the substate
accuracy, it is free to expose only the extended state and omit the
substate attribute.

* @get_regs_len: Get buffer length required for @get_regs
* @get_regs: Get device registers
* @get_wol: Report whether Wake-on-Lan is enabled
* @set_wol: Turn Wake-on-Lan on or off. Returns a negative error code

* @get_msglevel: Report driver message level. This should be the value
* of the @msg_enable field used by netif logging functions.
* @set_msglevel: Set driver message level
* @nway_reset: Restart autonegotiation. Returns a negative error code
* or zero.
* @get_link: Report whether physical link is up. Will only be called if

* which uses netif_carrier_ok().
* @get_link_ext_state: Report link extended state. Should set link_ext_state and
* link_ext_substate (link_ext_substate of 0 means link_ext_substate is unknown,
* do not attach ext_substate attribute to netlink message). If link_ext_state
* and link_ext_substate are unknown, return -ENODATA. If not implemented,
* link_ext_state and link_ext_substate will not be sent to userspace.
* @get_eeprom: Read data from the device EEPROM.
* Should fill in the magic field. Don't need to check len for zero
* or wraparound. Fill in the data argument with the eeprom values
* from offset to offset + len. Update len to the amount read.
* Returns an error or zero.
* @set_eeprom: Write data to the device EEPROM.
* Should validate the magic field. Don't need to check len for zero
* or wraparound. Update len to the amount written. Returns an error
* or zero.
* @get_coalesce: Get interrupt coalescing parameters. Returns a negative

* @set_phys_id: Identify the physical devices, e.g. by flashing an LED
* attached to it. The implementation may update the indicator
* asynchronously or synchronously, but in either case it must return
* quickly. It is initially called with the argument %ETHTOOL_ID_ACTIVE,
* and must either activate asynchronous updates and return zero, return
* a negative error or return a positive frequency for synchronous
* indication (e.g. 1 for one on/off cycle per second). If it returns
* a frequency then it will be called again at intervals with the
* argument %ETHTOOL_ID_ON or %ETHTOOL_ID_OFF and should set the state of
* the indicator accordingly. Finally, it is called with the argument
* %ETHTOOL_ID_INACTIVE and must deactivate the indicator. Returns a
* negative error code or zero.
* @get_ethtool_stats: Return extended statistics about the device.
* This is only useful if the device maintains statistics not
* included in &struct rtnl_link_stats64.
* @begin: Function to be called before any other operation. Returns a
* negative error code or zero.

* Returns zero if not supported for this specific device.
* @get_rxfh_indir_size: Get the size of the RX flow hash indirection table.
* Returns zero if not supported for this specific device.
* @get_rxfh: Get the contents of the RX flow hash indirection table, hash key
* and/or hash function.
* Returns a negative error code or zero.
* @set_rxfh: Set the contents of the RX flow hash indirection table, hash
* key, and/or hash function. Arguments which are set to %NULL or zero

* @get_dump_data: Get dump data.
* @set_dump: Set dump specific flags to the device.
* @get_ts_info: Get the time stamping and PTP hardware clock capabilities.
* Drivers supporting transmit time stamps in software should set this to
* ethtool_op_get_ts_info().
* @get_module_info: Get the size and type of the eeprom contained within
* a plug-in module.
* @get_module_eeprom: Get the eeprom information from the plug-in module
* @get_eee: Get Energy-Efficient (EEE) supported and status.
* @set_eee: Set EEE status (enable/disable) as well as LPI timers.
* @get_per_queue_coalesce: Get interrupt coalescing parameters per queue.
* It must check that the given queue number is valid. If neither a RX nor
* a TX queue has this number, return -EINVAL. If only a RX queue or a TX
* queue has this number, set the inapplicable fields to ~0 and return 0.
* Returns a negative error code or zero.
* @set_per_queue_coalesce: Set interrupt coalescing parameters per queue.
* It must check that the given queue number is valid. If neither a RX nor
* a TX queue has this number, return -EINVAL. If only a RX queue or a TX
* queue has this number, ignore the inapplicable fields. Supported
* coalescing types should be set in @supported_coalesce_params.
* Returns a negative error code or zero.
* @get_link_ksettings: Get various device settings including Ethernet link
* settings. The %cmd and %link_mode_masks_nwords fields should be
* ignored (use %__ETHTOOL_LINK_MODE_MASK_NBITS instead of the latter),

* error code or zero.
* @set_link_ksettings: Set various device settings including Ethernet link
* settings. The %cmd and %link_mode_masks_nwords fields should be
* ignored (use %__ETHTOOL_LINK_MODE_MASK_NBITS instead of the latter),
* any change to them will be overwritten by kernel. Returns a negative
* error code or zero.
* @get_fecparam: Get the network device Forward Error Correction parameters.
* @set_fecparam: Set the network device Forward Error Correction parameters.
* @get_ethtool_phy_stats: Return extended statistics about the PHY device.
* This is only useful if the device maintains PHY statistics and
* cannot use the standard PHY library helpers.
*
* All operations are optional (i.e. the function pointer may be set
* to %NULL) and callers must take this into account. Callers must
* hold the RTNL lock.
*
* See the structures used by these operations for further documentation.
* Note that for all operations using a structure ending with a zero-
* length array, the array is allocated separately in the kernel and
* is passed to the driver as an additional parameter.
*
* See &struct net_device and &struct net_device_ops for documentation
