From 549fdd34b5f2dfa63e10855f20796c13a036707b Mon Sep 17 00:00:00 2001 From: Philipp Borgers Date: Mon, 25 Jan 2021 16:07:44 +0100 Subject: mac80211: add STBC encoding to ieee80211_parse_tx_radiotap This patch adds support for STBC encoding to the radiotap tx parse function. Prior to this change adding the STBC flag to the radiotap header did not encode frames with STBC.
