Date: Fri, 15 Sep 2023 18:09:57 +0200
From: Philipp Hortmann <philipp.g.hortmann@...il.com>
To: Greg Kroah-Hartman <gregkh@...uxfoundation.org>,
linux-staging@...ts.linux.dev, linux-kernel@...r.kernel.org
Subject: [PATCH 16/16] staging: rtl8192e: Replace frame control constants
with IEEE80211_FCTL_*
Replace frame control fields with IEEE80211_FCTL_* to avoid proprietary
constant names.
