From 5806ef25bc6e6cf0c04005ff25a4585437d567de Mon Sep 17 00:00:00 2001 From: Benjamin Berg Date: Sun, 27 Aug 2023 14:05:22 +0300 Subject: wifi: cfg80211: add ieee80211_fragment_element to public API This function will be used by the kunit tests within cfg80211. As it is generally useful, move it from mac80211 to cfg80211.
