Problem running PTP on latest linux (

[ievenbach]

Hello,
I have a board based on Sparx5i chip, and am running in "standalone" mode - that is without MESA.
I use latest BSP (bsp-6.6-2024 branch).

I am trying to run ptp4l on it. It succeeds, if I run it once, with single port.
But if I restart it, or try to run with multiple ports, I see an error:

root@medusa:~# ptp4l -2 -i eth0 -m
ptp4l[2719.892]: selected /dev/ptp0 as PTP clock
ptp4l[2719.940]: driver rejected most general HWTSTAMP filter
ptp4l[2719.940]: ioctl SIOCSHWTSTAMP failed: Cannot allocate memory
ptp4l[2719.972]: port 1 (eth0): INITIALIZING to FAULTY on FAULT_DETECTED (FT_UNSPECIFIED)

I tracked it down to sparx5_ptp_add_trap() - it fails in call to sparx5_add_ptp_key so far, but didn't go
much further.
Is there a quick fix by any chance?
