[PATCH net-next 00/30] net: dsa: mt7530: improve, trap BPDU & LLDP, and prefer CPU port

[arinc9.unal at gmail.com]

Hello!

This patch series simplifies the code, improves the logic of the switch
hardware support, traps LLDP frames and BPDUs for MT7530, MT7531, and
MT7988 SoC switches, and introduces the preferring local CPU port
operation.

There's also a patch for fixing the port capabilities of the switch on the
MT7988 SoC.

I have done a bidirectional speed test using iperf3 on all ports of the
MT7530 and MT7531 switches with this patch series applied. I have tested
every possible configuration on the MCM and standalone MT7530 and MT7531
switch. I'll let the name of the dtb files speak for themselves.
