[PATCH net-next v2 4/4] net: dsa: hellcreek: Add missing PTP via UDP rules
flat view
STALE1761d
From: Kurt Kanzenbach <kurt@linutronix.de>

Subsystem:
hirschmann hellcreek ethernet switch driver, networking drivers, networking [dsa], the rest · Maintainers:
Kurt Kanzenbach, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Andrew Lunn, Vladimir Oltean, Linus Torvalds
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")
