MT7623NI does not come with the MT7530 switch. MT7623AI does.

It's not an MT7530-like switch, it's the MT7530 switch, which is part of 
the multi-chip module, in a chip-stack package.

To be more specific, it's only the MT7621AT, MT7621DAT, and MT7621ST 
SoCs. MT7621NT SoC don't have it.

BPI-R2 has MT7623NI SoC, not MT7623AI. The MT7530 switch in this device 
is standalone.
