Subject: [PATCH] iw: support 160MHz frequency command for 6GHz band
Date: Sat, 12 Mar 2022 17:09:04 +0800	[thread overview]
Message-ID: <4366b069d41f469c36554c8dcfc857b5aedf3e1d.1647075278.git.deren.wu@mediatek.com> (raw)

From: Deren Wu <deren.wu@mediatek.com>

Add support to configure 160MHz in 6G band by direct
channel/frequency command.

Example:
iw dev <interface> set freq 6195 160MHz
