net: phy: broadcom: Add support code for downshift/Wirespeed
Broadcom's Wirespeed feature allows us to configure how auto-negotiation should behave with fewer working pairs of wires on a cable. Add support code for retrieving and setting such downshift counters using the recently added ethtool downshift tunables. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
