Subject: Re: [PATCH net-next v3 4/4] net: lan966x: Add ptp trap rules

This gives me:
# /etc/init.d/S65ptp4l start
Starting linuxptp daemon: OK
[ 44.136870] vcap_val_rule:1678: keyset was not updated: -22
[ 44.140196] vcap_val_rule:1678: keyset was not updated: -22
#
# ptp4l -v
3.1.1
# uname -a
Linux buildroot 6.1.0-rc8-next-20221208+ #924 SMP Thu Dec 8 10:08:58 CET 2022 armv7l GNU/Linux
I don't know whats going on, but I'm happy to help with debugging with some
guidance.
