Subject: [PATCH 11/17] net: dsa: mt7530: fix 10M/100M speed on MT7988 switch
Git-commit: dfa988b4c7c3a48bde7c2713308920c7741fff29
Patch-mainline: v6.8-rc3
References: git-fixes
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.
