From 23ca3b727ee6b432166391607b614d3a6beb6784 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Sat, 6 Feb 2021 00:02:19 +0200 Subject: net: mscc: ocelot: rebalance LAGs on link up/down events At present there is an issue when ocelot is offloading a bonding interface, but one of the links of the physical ports goes down. Traffic keeps being hashed towards that destination, and of course gets dropped on egress. Monitor the netdev notifier events emitted by the bonding driver for changes in the physical state of lower interfaces, to determine which ports are active and which ones are no longer. Then extend ocelot_get_bond_mask to return either the configured bonding interfaces, or the active ones, depending on a boolean argument. The code that does rebalancing only needs to do so among the active ports, whereas the bridge forwarding mask and the logical port IDs still need to look at the permanently bonded ports.
