Subject: [PATCH] net: phy: populate host_interfaces when attaching PHY
|
|
|
|
Use bitmask of interfaces supported by the MAC for the PHY to choose
|
|
from if the declared interface mode is among those using a single pair
|
|
of SerDes lanes.
|
|
This will allow 2500Base-T PHYs to switch to SGMII on most hosts, which
|
|
results in half-duplex being supported in case the MAC supports them.
|
|
Without this change, 2500Base-T PHYs will always operate in 2500Base-X
|
|
mode with rate-matching, which is not only wasteful in terms of energy
|
|
consumption, but also limits the supported interface modes to
|
|
full-duplex only.
