From a471be41f2bfe4ee3a4b38b0e5af17d0abfd3aa6 Mon Sep 17 00:00:00 2001 From: Scott Feldman Date: Wed, 23 Sep 2015 08:39:14 -0700 Subject: [PATCH] rocker: track when FDB entry is touched. The entry is touched once when created, and touched again for each update. The touched time is used to calculate FDB entry age.
