From 686c603f67ae87bf21a61b5e4b1564443f41c3ee Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Thu, 20 Oct 2022 03:34:43 +0200 Subject: [PATCH] net: permit ieee80211_ptr even with no CFG82111 support Introduce a new flag CONFIG_CFG80211_HEADERS to compile in ieee80211_ptr even if CFG80211 support is not compiled in. This is needed for the backports project and for any downstream wireless driver that loads in the kernel dynamically.
