# \[net-next PATCH 10/19\] net: dsa: qca8k: add support for port fast aging - From: Ansuel Smith \ - Date: 2021-11-17 21:06:34 - List: netdev - Page: https://ratatoskr.run/netdev/2021/11/1578008 - Thread: https://ratatoskr.run/netdev/2021/11/1577999/t.md ```text The switch doesn't support fast aging but it does support the flush of the ARL table for a specific port. Add this function to simulate fast aging and proprely support stp state set.
