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.
