From 394f34a5792b091a6722e5a804e4875f0b87f311 Mon Sep 17 00:00:00 2001 From: Sam Leffler Date: Mon, 31 Aug 2009 21:25:49 +0000 Subject: [PATCH] On resume in sta mode program the beacon timers so when roaming (and the previous ap is no longer in range) the device will deliver bmiss interrupts and trigger the state machine. Also arrange to sync the beacon timers on the next received beacon frame so that when we don't roam we re-synchronize with the ap.
