From e02281e7a5c524aaf6a52bb01afc4cc49addb908 Mon Sep 17 00:00:00 2001 From: Mathy Vanhoef Date: Thu, 23 Jul 2020 14:01:49 +0400 Subject: mac80211: add radiotap flag to prevent sequence number overwrite The radiotap specification contains a flag to indicate that the sequence number of an injected frame should not be overwritten. Parse this flag and define and set a corresponding Tx control flag.
