3 Subject: [PATCH] net: phy: broadcom: Allow enabling or disabling of EEE
4
5 In preparation for adding support for Wirespeed/downshift, we need to
6 change bcm_phy_eee_enable() to allow enabling or disabling EEE, so make
7 the function take an extra enable/disable boolean parameter and rename
8 it to illustrate it sets EEE, not necessarily just enables it.
