From 2eb71d7d7ab0b4b1dc762630fc7009c0f7266c9b Mon Sep 17 00:00:00 2001 From: Alexandru Gagniuc Date: Thu, 6 Apr 2023 18:05:50 -0500 Subject: [PATCH] batman-adv: fix compilation bug in batadv_is_cfg80211_netdev() Because batman-adv is built under backports, not a clean linux tree, the CONFIG_CFG80211 does not exist. The evaluation of IS_ENABLED() in batadv_is_cfg80211_netdev() will be false, causing the funtion to always return false. This means that the wifi_flags of an interface don't get set, causing batadv_is_wifi_hardif() to always return false. As a result, batadv_v_elp_get_throughput() never tries to get the station info from cfg80211, resulting in the following warning: batman_adv: bat0: WiFi driver or ethtool info does not provide information about link speeds on interface phy1-mesh0, therefore defaulting to hardcoded throughput values of 1.0 Mbps. So replace CONFIG_CFG80211 with CPTCFG_CFG80211, which is the correct macro to use under backports.
