Merge branch 'bcmgenet-net'
Florian Fainelli says:
====================
net: bcmgenet: power management related fixes
These two patches fixes issues seen while testing power management on
platforms using the GENET driver.
First patch fixes an issue with the PHY state machine queuing work after
resume since we are not properly detached from it.
Second patch fixes an issue with GENET interfaces that were not properly
restored to a working state after a S3 suspend/resume cycle.
