From c1e3330f22bc3c53e6a2c4282dd5a1dc6e6bcca1 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Mon, 5 Dec 2016 22:52:45 +0100 Subject: [PATCH] ath10k: add accounting for the extended peer statistics The 10.4 firmware adds extended peer information to the firmware's statistics payload. This additional info is stored as a separate data field and the elements are stored in their own "peers_extd" list. These elements can pile up in the same way as the peer information elements. This is because the ath10k_wmi_10_4_op_pull_fw_stats() function tries to pull the same amount (num_peer_stats) for every statistic data unit.
