Subject: [PATCH 2/2] net: phy: at803x: make read specific status function more
|
||
|
|
generic
|
||
|
|
|
||
|
|
Rework read specific status function to be more generic. The function
|
||
|
|
apply different speed mask based on the PHY ID. Make it more generic by
|
||
|
|
adding an additional arg to pass the specific speed (ss) mask and use
|
||
|
|
the provided mask to parse the speed value.
|
||
|
|
|
||
|
|
This is needed to permit an easier deatch of qca808x code from the
|
||
|
|
at803x driver.
