Subject: Re: [PATCH net-next 0/7] net: dsa: mv88e6xxx: Add devlink regions support

I tested this on the Rev C Zii Vybrid Dev Board which has two Marvell
88E6390X switches.

Both switches worth of port, global, and atu data show up when running
the devlink show command and for each of the regions, I can dump the
contents.

I also tested on a different platform with a single 88E6352.

Full series is:
