Subject: [PATCH 01/18] staging: rtl8723bs: remove all 5Ghz network types
Date:   Sat, 19 Jun 2021 12:47:04 +0200
Message-Id: <96b241e97e425a3115305b3d6658037e1e4c862c.1624099125.git.fabioaiuto83@gmail.com>

Content-Transfer-Encoding: 8bit
Precedence: bulk

remove all 5Ghz network types. rtl8723bs works on
802.11bgn standards and on 2.4Ghz band.

So remove all code related to 802.11a and 802.11ac
standards, which the device doesn't support.
