BPDUs are link-local frames, therefore they must be trapped to the CPU
port. Currently, the MT7530 switch treats BPDUs as regular multicast
frames, therefore flooding them to user ports. To fix this, set BPDUs to be
trapped to the CPU port. Group this on mt7530_setup() and
mt7531_setup_common() into mt753x_trap_frames() and call that.
