Subject: [PATCH v2 net 0/5] Ocelot PTP fixes

This is another attempt at "net: mscc: ocelot: be resilient to loss of
PTP packets during transmission".
https://lore.kernel.org/netdev/20241203164755.16115-1-vladimir.oltean@nxp.com/

The central change is in patch 4/5. It recovers a port from a very
reproducible condition where previously, it would become unable to take
any hardware TX timestamp.

Then we have patches 1/5 and 5/5 which are extra bug fixes.

Patches 2/5 and 3/5 are logical changes split out of the monolithic
patch previously submitted as v1, so that patch 4/5 is hopefully easier
to follow.

Vladimir Oltean (5):
  net: mscc: ocelot: fix memory leak on ocelot_port_add_txtstamp_skb()
  net: mscc: ocelot: improve handling of TX timestamp for unknown skb
  net: mscc: ocelot: ocelot->ts_id_lock and ocelot_port->tx_skbs.lock
    are IRQ-safe
  net: mscc: ocelot: be resilient to loss of PTP packets during
    transmission
  net: mscc: ocelot: perform error cleanup in ocelot_hwstamp_set()
