Subject: [PATCH] net: phy: broadcom: Allow enabling or disabling of EEE
|
||
|
|
|
||
|
|
In preparation for adding support for Wirespeed/downshift, we need to
|
||
|
|
change bcm_phy_eee_enable() to allow enabling or disabling EEE, so make
|
||
|
|
the function take an extra enable/disable boolean parameter and rename
|
||
|
|
it to illustrate it sets EEE, not necessarily just enables it.
