Based on previous RFCs from Maxim Georgiev:

this series attempts to introduce new API for the hardware timestamping
control path (SIOCGHWTSTAMP and SIOCSHWTSTAMP handling).

I don't have any board with phylib hardware timestamping, so I would
appreciate testing (especially on lan966x, the most intricate
conversion). I was, however, able to test netdev level timestamping,
because I also have some more unsubmitted conversions in progress:

https://github.com/vladimiroltean/linux/commits/ndo-hwtstamp-v7

I hope that the concerns expressed in the comments of previous series
were addressed, and that Köry Maincent's series:
https://lore.kernel.org/netdev/20230406173308.401924-1-kory.maincent@bootlin.com/ (local)
can make progress in parallel with the conversion of the rest of drivers.

Maxim Georgiev (5):
  net: add NDOs for configuring hardware timestamping
  net: add hwtstamping helpers for stackable net devices
  net: vlan: convert to ndo_hwtstamp_get() / ndo_hwtstamp_set()
  net: macvlan: convert to ndo_hwtstamp_get() / ndo_hwtstamp_set()
  net: bonding: convert to ndo_hwtstamp_get() / ndo_hwtstamp_set()

Vladimir Oltean (5):
  net: fec: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set()
  net: fec: delete fec_ptp_disable_hwts()
  net: sparx5: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set()
  net: lan966x: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set()
  net: remove phy_has_hwtstamp() -> phy_mii_ioctl() decision from
    converted drivers

Vladimir, thank you for taking over and improving this patch stack!

I see you dropped the netdevsim patch:
https://www.spinics.net/lists/netdev/msg901378.html
Do you believe it's not useful any more since the rest of the
patches in the stack were tested through other means?
