From 4f9fb990013c03c5d56266fb4c439816cd84e1a6 Mon Sep 17 00:00:00 2001 From: Ganapathi Bhat Date: Tue, 8 May 2018 00:10:58 +0530 Subject: [PATCH] mwifiex: increase TX threashold to avoid TX timeout during ED MAC test While carrying energy detection(ED) tests, the chip will stop transmission upon detecting an energy in the connected channel. As a feedback, driver will stop dequeuing TX packets and due to which wmm_tx_pending keep incremeting. Once wmm_tx_pending reaches 100, driver calls netif_tx_stop_queue(). If TX ques is not restarted within 5(watchdog_timeo) seconds, it will result in TX timeout. The ED test is carried out for one minute and the current threshold of 100 is easily overcome by the traffic, cuasing TX timeouts. To fix this increase the threshold to 400.
