Testing selectable timestamping - where are the tools for this feature?

["Russell King (Oracle)" <linux@armlinux.org.uk>]

Hi Kory,

I've finally found some cycles (and time when I'm next to the platform)
to test the selectable timestamping feature. However, I'm struggling to
get it to work.

In your email
https://lore.kernel.org/20240709-feature_ptp_netnext-v17-0-b5317f50df2a@bootlin.com/
you state that "You can test it with the ethtool source on branch
feature_ptp of: https://github.com/kmaincent/ethtool". I cloned this
repository, checked out the feature_ptp branch, and while building
I get the following warnings:

netlink/desc-ethtool.c:241:37: warning: ‘__ts_desc’ defined but not used [-Wunus
ed-const-variable=]
  241 | static const struct pretty_nla_desc __ts_desc[] = {
      |                                     ^~~~~~~~~
netlink/ts.c: In function ‘ts_get_reply_cb’:
netlink/ts.c:23:14: warning: unused variable ‘str’ [-Wunused-variable]

 4817 | static int do_list_ptp(struct cmd_context *ctx)
      |            ^~~~~~~~~~~

My conclusion is... your ethtool sources for testing this feature are
broken, or this is no longer the place to test this feature.

Presumably there _is_ something somewhere that allows one to exercise
this new code that Jakub merged on July 15th (commit 30b356005048)?
Please could you point me in the appropriate direction ASAP - time is
very short if I'm going to give this a test on the setup where both
the MAC and PHY support PTP. Essentially, this afternoon - or its
going to be at least a month before the next opportunity.

Thanks.
