Igor Russkikh c6db31ffe2 ethtool: allow netdev driver to define phy tunables 
Define get/set phy tunable callbacks in ethtool ops.
This will allow MAC drivers with integrated PHY still to implement
these tunables.

* implemented, the @driver and @bus_info fields will be filled in
* according to the netdev's parent device.
* @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
* or zero.
* @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
* the netdev is up. Should usually be set to ethtool_op_get_link(),
* 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

* @get_ringparam: Report ring sizes
* @set_ringparam: Set ring sizes. Returns a negative error code or zero.
* @get_pause_stats: Report pause frame statistics. Drivers must not zero
* statistics which they don't report. The stats structure is initialized
* to ETHTOOL_STAT_NOT_SET indicating driver does not report statistics.
* @get_pauseparam: Report pause parameters
* @set_pauseparam: Set pause parameters. Returns a negative error code
* or zero.
* @self_test: Run specified self-tests
* @get_strings: Return a set of strings that describe the requested objects
* @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.
* @complete: Function to be called after any other operation except
* @begin. Will be called even if the other operation failed.

* error code or zero.

* error code or zero.
* @set_rxnfc: Set RX flow classification rules. Returns a negative
* error code or zero.
* @flash_device: Write a firmware image to device's flash memory.
* Returns a negative error code or zero.
* @reset: Reset (part of) the device, as specified by a bitmask of
* flags from &enum ethtool_reset_flags. Returns a negative
* error code or zero.
* @get_rxfh_key_size: Get the size of the RX flow hash key.
* 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.

* hash key, and/or hash function assiciated to the given rss context.
* Returns a negative error code or zero.
* @set_rxfh_context: Create, remove and configure RSS contexts. Allows setting
* the contents of the RX flow hash indirection table, hash key, and/or

* and flag of the device.
* @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),
* any change to them will be overwritten by kernel. Returns a negative
* 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
