Subject: [PATCH 57/82] net: sparx5: add feature support
|
|
|
|
Lan969x supports a number of different features, depending on the
|
|
target. Add new field sparx5->features and initialize the features based
|
|
on the target. Also add the function sparx5_has_feature() and use it
|
|
throughout. For now, we only need to handle features: PSFP and PTP -
|
|
more will come in the future.
