From abca1237820a7d9a087b2744a2abd1026364d7b7 Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Tue, 12 Mar 2013 17:19:46 +0200 Subject: [PATCH] wlcore: consider dummy packets when tx queues are empty Don't ignore dummy packets when our queues are empty. This causes dummy packets never to be sent when traffic is not suspended by FW thresholds, which happens only in high Tx throughput situations. This may hurt Rx performance.
