- Subject: [PATCH 13/13] net: dsa: qca8k: add op to get ports netdev
- In order that the LED trigger can blink the switch MAC ports LED, it
- needs to know the netdev associated to the port. Add the callback to
- return the struct device of the netdev.
- Add an helper function qca8k_phy_to_port() to convert the phy back to
- dsa_port index, as we reference LED port based on the internal PHY
- index and needs to be converted back.
