Commit under fixes switched to uAPI generation from the YAML
spec. A number of custom defines were left behind, mostly
for commands very hard to express in YAML spec.
Among what was left behind was the name and version of
the generic netlink family. Problem is that the codegen
always outputs those values so we ended up with a duplicated,
differently named set of defines.
Provide naming info in YAML and remove the incorrect defines.
Fixes: 8d0580c6ebdd ("ethtool: regenerate uapi header from the spec")

Multi-PTP source support within a network topology has been merged,
but the hardware timestamp source is not yet exposed to users.
Currently, users only see the PTP index, which does not indicate
whether the timestamp comes from a PHY or a MAC.
Add support for reporting the hwtstamp source using a
hwtstamp-source field, alongside hwtstamp-phyindex, to describe
the origin of the hardware timestamp.
Remove HWTSTAMP_SOURCE_UNSPEC enum value as it is not used at all.

The phy-upstream enum is already defined in the ethtool.h UAPI header
and used by the ethtool userspace tool. However, the ethtool spec does
not reference it, causing YNL to auto-generate a duplicate and redundant
enum.
Fix this by updating the spec to reference the existing UAPI enum
in ethtool.h.

For packets with two-step timestamp requests, the hardware timestamp
comes back to the driver through a confirmation mechanism of sorts,
which allows the driver to confidently bump the successful "pkts"
counter.
For one-step PTP, the NIC is supposed to autonomously insert its
hardware TX timestamp in the packet headers while simultaneously
transmitting it. There may be a confirmation that this was done
successfully, or there may not.
None of the current drivers which implement ethtool_ops :: get_ts_stats()
also support HWTSTAMP_TX_ONESTEP_SYNC or HWTSTAMP_TX_ONESTEP_SYNC, so it
is a bit unclear which model to follow. But there are NICs, such as DSA,
where there is no transmit confirmation at all. Here, it would be wrong /
misleading to increment the successful "pkts" counter, because one-step
PTP packets can be dropped on TX just like any other packets.
So introduce a special counter which signifies "yes, an attempt was made,
but we don't know whether it also exited the port or not". I expect that
for one-step PTP packets where a confirmation is available, the "pkts"
counter would be bumped.

The hds-thresh option configures the threshold value of
the header-data-split.
If a received packet size is larger than this threshold value, a packet
will be split into header and payload.
The header indicates TCP and UDP header, but it depends on driver spec.
The bnxt_en driver supports HDS(Header-Data-Split) configuration at
FW level, affecting TCP and UDP too.
So, If hds-thresh is set, it affects UDP and TCP packets.
Example:
# ethtool -G <interface name> hds-thresh <value>
# ethtool -G enp14s0f0np0 tcp-data-split on hds-thresh 256
# ethtool -g enp14s0f0np0
Ring parameters for enp14s0f0np0:
Pre-set maximums:
...
HDS thresh: 1023
Current hardware settings:
...
TCP data split: on
HDS thresh: 256
The default/min/max values are not defined in the ethtool so the drivers
should define themself.
The 0 value means that all TCP/UDP packets' header and payload
will be split.

Introduce support for ETHTOOL_MSG_TSCONFIG_GET/SET ethtool netlink socket
to read and configure hwtstamp configuration of a PHC provider. Note that
simultaneous hwtstamp isn't supported; configuring a new one disables the
previous setting.

Either the MAC or the PHY can provide hwtstamp, so we should be able to
read the tsinfo for any hwtstamp provider.
Enhance 'get' command to retrieve tsinfo of hwtstamp providers within a
network topology.
Add support for a specific dump command to retrieve all hwtstamp
providers within the network topology, with added functionality for
filtered dump to target a single interface.

No functional changes. Mostly the following formatting:
- extra docs
- extra enums
- XXX_MAX = __XXX_CNT - 1 -> XXX_MAX = (__XXX_CNT - 1)
- newlines

Reshuffle definitions that are gonna be generated into
ethtool_netlink_generated.h and match ynl spec order.
This should make it easier to compare the output of the ynl-gen-c
to the existing uapi header. No functional changes.
Things that are still remaining to be manually defined:
- ETHTOOL_FLAG_ALL - probably no good way to add to spec?
- some of the cable test bits (not sure whether it's possible to move to
spec)
- some of the stats definitions (no way currently to move to spec)
