2013-05-27net: ethernet: remove unnecessary platform_set_drvdata()Jingoo Han
The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is not needed to manually clear the device driver data to NULL.

2013-05-14net/macb: fix ISR clear-on-write behavior only for some SoCNicolas Ferre
Commit 749a2b6 (net/macb: clear tx/rx completion flags in ISR) introduces clear-on-write on ISR register. This behavior is not always implemented when using Cadence MACB/GEM and is breaking other platforms. We are using the Design Configuration Register 1 information and a capability property to actually activate this clear-on-write behavior on ISR.

2013-01-14net: phy: remove flags argument from phy_{attach, connect, connect_direct}Florian Fainelli
The flags argument of the phy_{attach,connect,connect_direct} functions is then used to assign a struct phy_device dev_flags with its value. All callers but the tg3 driver pass the flag 0, which results in the underlying PHY drivers in drivers/net/phy/ not being able to actually use any of the flags they would set in dev_flags. This patch gets rid of the flags argument, and passes phydev->dev_flags to the internal PHY library call phy_attach_direct() such that drivers which actually modify a phy device dev_flags get the value preserved for use by the underlying phy driver.

2012-11-03macb: Keep driver's speed/duplex in sync with actual NCFGRVitalii Demianets
When underlying phy driver restores its state very fast after being brought down and up so that macb driver function macb_handle_link_change() was never called with link state "down", driver's internal representation of phy speed and duplex (bp->speed and bp->duplex) didn't change. So, macb driver sees no reason to perform actual write to the NCFGR register, although the speed and duplex settings in that register were reset when interface was brought down and up. In that case actual phy speed and duplex differ from NCFGR settings. The patch fixes that by keeping internal driver representation of speed and duplex in sync with actual content of NCFGR.
