Danielle Ratson c8907043c6 ethtool: Get link mode in use instead of speed and duplex parameters 
Currently, when user space queries the link's parameters, as speed and
duplex, each parameter is passed from the driver to ethtool.

Instead, get the link mode bit in use, and derive each of the parameters
from it in ethtool.

* @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

* 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.

* @set_eee: Set EEE status (enable/disable) as well as LPI timers.
* @get_per_queue_coalesce: Get interrupt coalescing parameters per queue.

* 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

* Returns a negative error code or zero.
* @get_link_ksettings: Get various device settings including Ethernet link

* @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),

* 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.
