Subject: [PATCH] mt76: mt7615: do not advertise 5 GHz on first phy of MT7615D (DBDC)
Date: Mon,  5 Jun 2023 10:34:07 +0300	[thread overview]
Message-ID: <20230605073408.8699-1-fercerpav@gmail.com> (raw)

On DBDC devices the first (internal) phy is only capable of using
2.4 GHz band, and the 5 GHz band is exposed via a separate phy object,
so avoid the false advertising.

Reported-by: Rani Hod <rani.hod@gmail.com>
Closes: https://github.com/openwrt/openwrt/pull/12361
Fixes: 7660a1bd0c22 ("mt76: mt7615: register ext_phy if DBDC is detected")
