f452518c98 net: phy: intel-xway: add VR9 v1.1 phy ids
The phys embedded into the v1.1 of the VR9 SoC are using different phy
ids. Add the phy ids to use the driver for this VR9 version as well.

5b73d9955f net: phy: intel-xway: add VR9 version number
The VR9 phy ids are matching only for the SoC version 1.2. Rename the
macros and change the names to take this into account.

a6d99fcd3f net: phy: switch remaining users to phy_(read|write)_mmd()
Switch everyone over to using phy_read_mmd() and phy_write_mmd() now
that they are able to handle both Clause 22 indirect addressing and
Clause 45 direct addressing methods to the MMD registers.

529ed12752 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,
unless there is a hardware erratum or other special case.  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.

This commit also effectively reverts the recently applied c7a61319
("net: phy: dp83848: Support ethernet pause frames").

So the new process is:

1) Unless the PHY driver overrides it, 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.
