Subject: [PATCH net-next 0/4] net: lan966x: Enable PTP on bridge interfaces 

Before it was not allowed to run ptp on ports that are part of a bridge
because in case of transparent clock the HW will still forward the frames
so there would be duplicate frames.
Now that there is VCAP support, it is possible to add entries in the VCAP
to trap frames to the CPU and the CPU will forward these frames.
The first part of the patch series, extends the VCAP support to be able to
modify and get the rule, while the last patch uses the VCAP to trap the ptp
frames.

Horatiu Vultur (4):
  net: microchip: vcap: Add vcap_get_rule
  net: microchip: vcap: Add vcap_mod_rule
  net: microchip: vcap: Add vcap_rule_get_key_u32
  net: lan966x: Add ptp trap rules
