From: Andy Fleming <afleming@...escale.com>
To: davem@...emloft.net
Cc: netdev@...r.kernel.org
Subject: [PATCH v2 1/2] phylib: Convert MDIO and PHY Lib drivers to support 10G
10G MDIO is a totally different protocol (clause 45 of 802.3).
Supporting this new protocol requires a couple of changes:
* Add a new parameter to the mdiobus_read functions to specify the
"device address" inside the PHY.
* Add a phy45_read command which takes advantage of that new parameter
* Add a generic PHY driver for 10G PHYs
* Convert all of the existing drivers to use the new format
Signed-off-by: Andy Fleming <afleming@...escale.com>

- int read(struct mii_bus *bus, int mii_id, int regnum);
-
- mii_id is the address on the bus for the PHY, and regnum is the register
- number. These functions are guaranteed not to be called from interrupt
- time, so it is safe for them to block, waiting for an interrupt to signal
- the operation is complete

+ internal device, and regnum is the register number. These functions are

2) A reset function is necessary. This is used to return the bus to an
initialized state.
