It has been brought to my attention that what had been fixed 1 year ago here for kernels 5.18 and later: https://lore.kernel.org/netdev/20230626155112.3155993-1-vladimir.oltean@nxp....
is still broken on linux-5.15.y. Short summary: PTP boundary clock is broken for ports under a VLAN-aware bridge.
The reason is that the Fixes: tags in those patches were wrong. The issue originated from earlier, but the changes from 5.18 (blamed there), aka DSA FDB isolation, masked that.
A straightforward cherry-pick was not possible, due to the conflict with the aforementioned DSA FDB isolation work from 5.18. So I redid patch 2/2 and marked what I had to adapt.
Tested on the NXP LS1021A-TSN board.

I'm sorry for the people who will want to backport DSA FDB isolation to linux-5.15.y :(
Now queued up, thanks.
