-Subject: [PATCH 020/203] net: mvneta: read MAC address from hardware when
- available
-
-This patch improves the logic used by the mvneta driver to find a MAC
-address for a particular interface. Until now, it was only looking at
-the Device Tree, and if no address was found, was falling back to
-generating a random MAC address.
-
-This patch adds the intermediate solution of reading the MAC address
-from the hardware registers, in case it has been set by the
-bootloader. So the order is now:
-
- 1) MAC address from the Device Tree
- 2) MAC address from the hardware registers
- 3) Random MAC address
-
-This requires moving the MAC address initialization a little bit later
-in the ->probe() code, because it now requires the hardware registers
-to be remapped.
