From 9a834b87c5544c347fd788cd9d4eb276402ab54a Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Thu, 31 May 2007 01:21:39 -0700 Subject: [PATCH] [BRIDGE]: Round off STP perodic timers. Peroidic STP timers don't have to be exact. The hold timer runs at 1HZ, and the hello timer normally runs at 2HZ; save power by aligning it them to next second.
