From 7b7da0a02192fd518c26c46dad6b14aca4569605 Mon Sep 17 00:00:00 2001 From: Vivek Natarajan Date: Mon, 31 Aug 2015 16:34:55 +0530 Subject: ath10k: drop probe responses when too many are queued In a noisy environment, when multiple interfaces are created, the management tx descriptors are fully occupied by the probe responses from all the interfaces. This prevents a new station from a successful association. Fix this by limiting the probe responses when the specified threshold limit is reached.
