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.

The ring_cookie is 64 bits wide which is much larger than can be used
for actual queue index values. So provide some helper routines to
pack a VF index into the cookie. This is useful to steer packets to
a VF ring without having to know the queue layout of the device.

We usually allocate special values of u32 fields starting from the top
down, so also change the value to 0xffffffff. As these operations
haven't been included in a stable release yet, it's not too late to

Convert the inline comments to kernel-doc format.
Explicitly specify that non-zero autoneg is an error if link
autonegotiation is disabled.
Specify that pause capabilities should be advertised dependent on link
autonegotiation, not the autoneg flag here. There is no way to
opt-out of pause frame autonegotiation, and this improves behaviour
when the link partner is configured to follow pause frame
autonegotiation and our interface is not.

Replace the 'deprecation' of some fields with a proper explanation of

struct ethtool_cmd has very limited documentation; it contains
several obscure or obsolete fields and several with non-obvious
interpretation.
Replace the inline comments (and some others below) with a full
explanation of the semantics as well as I understand them, in
kernel-doc format. Formally deprecate some fields that seem to be of
historical use only.

Add a comment which explains the real meaning of XCVR_INTERNAL (PHY and
Ethernet MAC in the same package/die) and XCVR_EXTERNAL (PHY and
Ethernet MAC in a different package/die). Most if not all of the drivers
setting their transceiver type already do it the way the comment
describes it.
