From 3bde2b68cfdeb3b68284172fa7759287a63cd981 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 10 Oct 2011 07:26:52 -0700 Subject: [PATCH] iwlagn: update beacon smarter Updating the beacon every time right after one was transmitted is pointless, most of the time we might not even have to update it. We will update it every time it changes, which includes from set_tim(), a callback iwlwifi didn't implement so far. This also reduces latency for clients, previously we would update the beacon right after the previous one was transmitted, and then a TIM change would only take effect after that again -- updating the beacon right after the TIM changes makes the TIM change go out to the air faster.
