[PATCH v1 0/6] net: phy: Ethernet PHY powerdown optimization

This is real v1 based on two RFCs sent earlier [1][2] to reduce power
consumption of network PHYs with link that are either unused or the
corresponding netdev is down.

Last RFC got Acked-by/Reviewed-by from Mugunthan and Florian, so it
was time to elevate the RFC to a real patch set. Compared to RFCv2
there is a simplification of phydev reference in patch 5, which was
suggested by Sergei Shtylyov.

Again, a branch with v1 applied to v3.13-rc2 can also be found at
