2013-07-30be2net: don't use dev_err when AER enabling failsIvan Vecera
The driver uses dev_err when enabling of AER fails (e.g. PCIe AER is not supported). The dev_info is more appropriate to avoid console pollution.

2013-07-29tg3: Fix UDP fragments treated as RMCPNithin Sujir

2013-07-29tg3: Enable support for timesync gpio outputNithin Sujir
The PTP_CAPABLE tg3 devices have a gpio output that is toggled when the free running counter matches a watchdog value. This patch adds support to set the watchdog and enable this feature. Since the output is controlled via bits in the EAV_REF_CLCK_CTL register, we have to read-modify-write it when we stop/resume.

2013-07-29tg3: Allow NVRAM programming when interface is downNithin Sujir
Previously, when the interface was brought down, the driver would set the power state to D3hot. In D3hot, we don't have access to the NVRAM. This patch removes the call to set the power state to PCI_D3hot in close. A following patch will implement the shutdown handler to properly set the D3hot state when the system is going down. Doing the above means that the TG3_PHYFLG_IS_LOW_POWER should not be checked to validate access to the NVRAM.

2013-07-29tg3: Remove incorrect switch to aux powerNithin Sujir
During probe, the driver is incorrectly switching the power to Vaux on the 5717 and later devices. At this point, we are in D0 state and drawing maximum power. We also definitely have Vmain available. It doesn't make sense to switch to Vaux since it has a lesser maximum power draw and we might go over the limit. On a new system, we observe that not all ports are recognized in some of the slots with this call in place.

2013-07-29net/mlx4_core: Respond to operation request by firmwareYevgeny Petrilin
This commit adds new firmware command and new firmware event. The firmware raises the MLX4_EVENT_TYPE_OP_REQUIRED event in order to signal the driver it needs to perform an administrative operation throughout the MLX4_CMD_GET_OP_REQ command. At the moment the supported operation is adding/removing multicast entries which are used by the firmware for handling NCSI traffic in B0 steering mode. Also, had to swap the order of mlx4_init_mcg_table() and mlx4_init_eq_table() to make sure that driver will get events only after resources are initialized to handle it.

HW: CQE error with index 0xFFFF - the BF WQE's control segment is STAMPED, so the BF index is 0xFFFF. Error: Invalid Opcode. As a result QP enters the error state and no traffic can be sent.

2013-07-28e1000e: ethtool unnecessarily takes device out of RPM suspendBruce Allan
A previous patch (commit e60b22c5b7 e1000e: fix accessing to suspended device) added .begin and .complete ethtool driver callbacks so that the device was resumed from Runtime Power Management (RPM) suspend state for all ethtool operations. This is overkill for operations which do not need to access any registers in the device.

2013-07-28e1000e: Tx hang on I218 when linked at 100Half and slow response at 10MbpsBruce Allan
Tx hang is an unintended consequence of another workaround that is in the EEPROM for an issue with the firmware at 10Mbps when K1 (a power mode of the MAC-PHY interconnect) is enabled. The issue is resolved by setting appropriate Tx re-transmission timeouts in the PHY and associated K1 entry times in the MAC to allow enough transmissions to occur without triggering a Tx hang. A similar change is needed when linked at 10Mbps to improve latency.

2013-07-25pch_gbe: Add MinnowBoard supportDarren Hart
The MinnowBoard uses an AR803x PHY with the PCH GBE which requires special handling. Use the MinnowBoard PCI Subsystem ID to detect this and add a pci_device_id.driver_data structure and functions to handle platform setup. The AR803x does not implement the RGMII 2ns TX clock delay in the trace routing nor via strapping. Add a detection method for the board and the PHY and enable the TX clock delay via the registers. This PHY will hibernate without link for 10 seconds. Ensure the PHY is awake for probe and then disable hibernation. A future improvement would be to convert pch_gbe to using PHYLIB and making sure we can wake the PHY at the necessary times rather than permanently disabling it.
