Subject: [PATCH] dpaa2-eth: Add autoneg support
|
|
|
|
For MC versions that support it, use the new DPNI link APIs, which
|
|
allow setting/getting of advertised and supported link modes.
|
|
|
|
A mapping between DPNI link modes and ethtool ones is created to
|
|
help converting from one to the other.
