A MGMT frame does override the blocked state according the the datasheet.Again, I do not know how other HW is designed, but all the SOC's we are working with, does allow us to add a TCAM rule which can redirect these frames to the CPU even on a blocked port.It is not in scope for what you are doing, but i wonder how we describe this in a generic Linux way? And then how we push it down to the hardware? For the Marvell Switches, it might be possible to do this without the TCAM. You can add forwarding DB entries marked as Management. It is unclear if this overrides the blocked state, but it would be a bit odd if it did not.
And any MAC address can be loaded, not only 01:80:C2:00:00:0x (802.1D) and 01:80:C2:00:00:2x (GARP). Then the ATU is used instead of something specialized.
