- From: Tobias Schramm <[email protected]>
- Subject: mvpp2: support fetching mac address from nvmem
- The mvpp2 driver did not query nvmem for hardware mac addresses. This
- patch adds querying of mac addresses stored in nvmem cells as a further
- fallback option before assigning a random address.
- Purposely added separately to fwnode_get_mac_address() above to maintain
- existing behaviour with builtin adapter mac address still taking
- precedence.
