Subject: [PATCH 5.16 0292/1039] net: dsa: hellcreek: Add missing PTP via UDP rules
From: Kurt Kanzenbach <kurt@...utronix.de>
[ Upstream commit 6cf01e451599da630ff1af529d61c5e4db4550ab ]
The switch supports PTP for UDP transport too. Therefore, add the missing static
FDB entries to ensure correct forwarding of these packets.
Fixes: ddd56dfe52c9 ("net: dsa: hellcreek: Add PTP clock support")
