From 69ed52dddc0fc64f5cec7e7384197874f92ff393 Mon Sep 17 00:00:00 2001 From: Wei Dai Date: Mon, 8 Aug 2016 14:39:51 +0800 Subject: [PATCH] lpm: fix freeing unused sub-table on rule delete When all rules with depth > 24 are deleted in a same sub-table (tlb8 group) and only a rule with depth <=24 is left in it, this sub-table (tlb8 group) should be recycled.
