Subject: [PATCH 22/48] net: dsa: mt7530: fix 10M/100M speed on MT7988 switch
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Setup PMCR port register for actual speed and duplex on internally
connected PHYs of the MT7988 built-in switch. This fixes links with
speeds other than 1000M.
Fixes: 110c18bfed41 ("net: dsa: mt7530: introduce driver for MT7988 built-in switch")
