From d2caad527c191563116809990081ab4fc0dafdb6 Mon Sep 17 00:00:00 2001 From: Benjamin Berg Date: Tue, 6 Sep 2022 14:26:52 +0200 Subject: wifi: mac80211: add API to show the link STAs in debugfs Create debugfs data per-link. For drivers, there is a new operation link_sta_add_debugfs which will always be called. For non-MLO, the station directory will be used directly rather than creating a corresponding subdirectory. As such, non-MLO drivers can simply continue to create the data from sta_debugfs_add.
