From 5150b45fd3553bf86b4a3d58d17146877480c0cc Mon Sep 17 00:00:00 2001 From: Aaron Kramer Date: Fri, 5 Apr 2019 13:31:36 -0400 Subject: [PATCH] net: hsr: Fix node prune function for forget time expiry HSR should forget nodes after configured node forget time expiry based on HSR_NODE_FORGET_TIME. As part of hsr_prune_nodes(), code checks to see if entries are to be flushed out if not heard for longer than forget time. But currently hsr_prune_nodes() is called only once during device creation. Restart the timer at the end of hsr_prune_nodes() so that hsr_prune_nodes() gets called periodically and forgotten entries are removed from node table.
