MT7530 is a 7-ports Gigabit Ethernet Switch that could be found on
Mediatek router platforms such as MT7623A or MT7623N which includes 7-port
Gigabit Ethernet MAC and 5-port Gigabit Ethernet PHY. Among these ports,
The port from 0 to 4 are the user ports connecting with the remote devices
while the port 5 and 6 are the CPU ports connecting into Mediatek Ethernet
GMAC.

The patch series integrated Mediatek MT7530 into DSA support which
includes the most of the essential callbacks such as tag insertion for
port distinguishing, port control, bridge offloading, STP setup and
ethtool operations to allow DSA to model each user port into independently
standalone netdevice as the other DSA driver had done.

Hi Sean,

very cool, i'll give this a spin this week and if it works out will 
import it into LEDE to get test coverage from our users.
