Jacob Keller eff3cddc22 clarify implementation of ethtool's get_ts_info op 
This patch adds some clarification about the intended way to implement
both SIOCSHWTSTAMP and ethtool's get_ts_info. The HWTSTAMP API has
several Rx filters which are very specific, as well as more general
filters. The specific filters really only exist to support some broken
hardware which can't fully implement the generic filters. This patch
adds clarification that it is okay to support the specific filters in
SIOCSHWTSTAMP by upscaling them to the generic filters. In addition,
update the header for ethtool_ts_info to specify that drivers ought to
only report the filters they support without upscaling in this manner.

* interface supports autonegotiation or auto-detection.
* Read-only.
* @advertising: Bitmask of %ADVERTISED_* flags for the link modes,
* physical connectors and other link features that are
* advertised through autonegotiation or enabled for
* auto-detection.
* @speed: Low bits of the speed
* @duplex: Duplex mode; one of %DUPLEX_*
* @port: Physical connector type; one of %PORT_*
* @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
* applicable. For clause 45 PHYs this is the PRTAD.
* @transceiver: Historically used to distinguish different possible
* PHY types, but not in a consistent way. Deprecated.
* @autoneg: Enable/disable autonegotiation and auto-detection;
* either %AUTONEG_DISABLE or %AUTONEG_ENABLE
* @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
* protocols supported by the interface; 0 if unknown.
* Read-only.
* @maxtxpkt: Historically used to report TX IRQ coalescing; now
* obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
* @maxrxpkt: Historically used to report RX IRQ coalescing; now

* @speed_hi: High bits of the speed
* @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
* %ETH_TP_MDI_*. If the status is unknown or not applicable, the
* value will be %ETH_TP_MDI_INVALID. Read-only.
* @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
* %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
* yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
* When written successfully, the link should be renegotiated if
* necessary.
* @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes
* and other link features that the link partner advertised
* through autonegotiation; 0 if unknown or not applicable.
* Read-only.
*
* The link speed in Mbps is split between @speed and @speed_hi. Use
* the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to
* access it.
*
* If autonegotiation is disabled, the speed and @duplex represent the
* fixed link mode and are writable if the driver supports multiple
* link modes. If it is enabled then they are read-only; if the link
* is up they represent the negotiated link mode; if the link is down,
* the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
* @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
*
* Some hardware interfaces may have multiple PHYs and/or physical
* connectors fitted or do not allow the driver to detect which are
* fitted. For these interfaces @port and/or @phy_address may be
* writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
* Otherwise, attempts to write different values may be ignored or
* rejected.
*
* Users should assume that all fields not marked read-only are
* writable and subject to validation by the driver. They should use
* %ETHTOOL_GSET to get the current values before making specific
* changes and then applying them with %ETHTOOL_SSET.
*
* Drivers that implement set_settings() should validate all fields
* other than @cmd that are not described as read-only or deprecated,
* and must ignore all fields described as read-only.
*
* Deprecated fields should be ignored by both users and drivers.

* It is illegal to set both usecs and max_frames to zero as this

*
* Some implementations ignore the value of max_frames and use the

* counting completions should validate that max_frames == !rx_usecs.
*
* Adaptive RX/TX coalescing is an algorithm implemented by some
* drivers to improve latency under low packet rates and improve
* throughput under high packet rates. Some drivers only implement
* one of RX or TX adaptive coalescing. Anything not implemented by
* the driver causes these values to be silently ignored.
