Subject: [PATCH] [v2] net: phy: phy drivers should not set SUPPORTED_[Asym_]Pause
Instead of having individual PHY drivers set the SUPPORTED_Pause and
SUPPORTED_Asym_Pause flags, phylib itself should set those flags.
During autonegotiation, the PHYs will determine whether to enable
pause frame support.
Pause frames are a feature that is supported by the MAC. It is the MAC
that generates the frames and that processes them. The PHY can only be
configured to allow them to pass through.
So the new process is:
1) Phylib sets the SUPPORTED_Pause and SUPPORTED_AsymPause bits in
phydev->supported. This indicates that the PHY supports pause frames.
2) The MAC driver checks phydev->supported before it calls phy_start().
If (SUPPORTED_Pause | SUPPORTED_AsymPause) is set, then the MAC driver
sets those bits in phydev->advertising, if it wants to enable pause
frame support.
3) When the link state changes, the MAC driver checks phydev->pause and
phydev->asym_pause, If the bits are set, then it enables the corresponding
features in the MAC. The algorithm is:
if (phydev->pause)
The MAC should be programmed to receive and honor
pause frames it receives, i.e. enable receive flow control.
if (phydev->pause != phydev->asym_pause)
The MAC should be programmed to transmit pause
frames when needed, i.e. enable transmit flow control.
