2014-01-19net: stmmac: Allocate and pass soc/board specific data to callbacksChen-Yu Tsai
The current .init and .exit callbacks requires access to driver private data structures. This is not a good seperation and abstraction. Instead, we add a new .setup callback for allocating private data, and pass the returned pointer to the other callbacks. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-01-19net: stmmac: Add support for optional reset controlChen-Yu Tsai
The DWMAC has a reset assert line, which is used on some SoCs. Add an optional reset control to stmmac driver core. To support reset control deferred probing, this patch changes the driver probe function to return the actual error, instead of just -EINVAL.

2014-01-19net: stmmac: Enable stmmac main clock when probing hardwareChen-Yu Tsai
The stmmac driver does not enable the main clock during the probe phase.

2014-01-18IB/mlx4: Handle Ethernet L2 parameters for IP based GID addressingMoni Shoua
IP based RoCE gids don't store Ethernet L2 parameters, MAC and VLAN. Therefore, we need to extract them from the CQE and place them in struct ib_wc (to be used for cases were they were taken from the gid). Also, when modifying a QP or building address handle, instead of parsing the dgid to get the MAC and VLAN, take them from the address handle attributes.

2014-01-17ixgbevf: redo dma mapping using the tx buffer infoEmil Tantilov
This patch takes advantage of the dma buffer always being present in the first descriptor and mapped as single. As such we can call dma_unmap_single and don't need to check for DMA mapping in ixgbevf_clean_tx_irq(). In addition this patch makes use of the DMA API.

2014-01-17ixgbevf: make the first tx_buffer a repository for most of the skb infoEmil Tantilov
This change makes it so that the first tx_buffer structure acts as a central storage location for most of the info about the skb we are about to transmit. In addition this patch makes tx_flags part of the ixgbevf_tx_buffer struct. This allows us to use the flags directly from the stucture and as result removes the tx_flags parameter from some functions. Also as a cleanup mapped_as_page is folded into tx_flags and some unused flags were removed.

2014-01-17ixgbevf: remove counters for Tx/Rx checksum offloadEmil Tantilov
This patch removes the Tx/Rx counters for checksum offload. The Tx counter was never updated and the Rx counter is of limited use. This is in effort to clean up the counters and make them consistent with the counters shown by ixgbe. Also this patch removes some members of the adapter structure that were never used and shuffles others to reduce number of holes. before: /* size: 1568, cachelines: 25, members: 48 */ /* sum members: 1519, holes: 10, sum holes: 43 */ /* padding: 6 */ /* last cacheline: 32 bytes */ after: /* size: 1480, cachelines: 24, members: 43 */ /* sum members: 1479, holes: 1, sum holes: 1 */ /* last cacheline: 8 bytes */ Signed-off-by: Alexander Duyck <alexander.h.duyck@intel.com> Signed-off-by: Emil Tantilov <emil.s.tantilov@intel.com> Tested-by: Phil Schmitt <phillip.j.schmitt@intel.com> Signed-off-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: David S.

2014-01-17i40e: add DCB and DCBNL supportNeerav Parikh
This patch adds capability to configure DCB on i40e network interfaces using Intel XL710 adapter firmware APIs. By default all VSIs are only enabled for the default traffic class enabled by firmware for any given PF. The driver would query the firmware for the traffic classes that are enabled for the port and reconfigure the LAN VSI to match to the port traffic class settings. All other VSIs are only enabled for the default traffic class settings for now. The driver registers and listens to firmware events that may require change in the DCB settings. It may reconfigure the VSI settings based on these events. This patch exposes IEEE DCBNL interfaces for the i40e driver to allow any application to query the DCB settings on the adapter.

2014-01-17i40e: implement DCB support infastructureNeerav Parikh
Intel XL710 series of adapters support QoS as per the IEEE 802.1 DCB (Data Center Bridging) standard. This is supported in conjuction with: - Enhanced Transmission Selection (ETS) - IEEE 802.1Qaz - Priority Flow Control (PFC) - IEEE 802.1Qbb - DCB eXchange Protocol (DCBX) - IEEE 802.1Qaz On Intel XL710 adapters DCBX is performed by the adapter firmware. The firmware runs DCBX in willing mode and configures the port as per the DCB settings recommended by it's link partner. By default in absence of any DCBX; firmware would configure the port with a single traffic class and all of the port bandwith will be allocated to that traffic class. This patch adds functions and calls to support querying and configuring DCB using firmware APIs.

2014-01-17i40e: refactor flow directorAnjali Singhai Jain
The i40e hardware was generating some inconsistent results when using current programming methods. This refactor fixes the inconsistencies that were preventing clean unloads of the driver, and moves the queues for handling flow director errors into their own hardware VSI. This patch also implements a corrected version of the basic ethtool add ntuple rule, which will disable the driver's automatic flow programming.

2014-01-16r6040: add delays in MDIO read/write polling loopsFlorian Fainelli
On newer and faster machines (Vortex X86DX) using the r6040 driver, it was noticed that the driver was returning an error during probing traced down to being the MDIO bus probing and the inability to complete a MDIO read operation in time. It turns out that the MDIO operations on these faster machines usually complete after ~2140 iterations which is bigger than 2048 (MAC_DEF_TIMEOUT) and results in spurious timeouts depending on the system load. Update r6040_phy_read() and r6040_phy_write() to include a 1 micro second delay in each busy-looping iteration of the loop which is a much safer operation than incrementing MAC_DEF_TIMEOUT.

2014-01-16e1000e: Fix compilation warning when !CONFIG_PM_SLEEPMika Westerberg
Commit 7509963c703b (e1000e: Fix a compile flag mis-match for suspend/resume) moved suspend and resume hooks to be available when CONFIG_PM is set. However, it can be set even if CONFIG_PM_SLEEP is not set causing following warnings to be emitted: drivers/net/ethernet/intel/e1000e/netdev.c:6178:12: warning: ‘e1000_suspend’ defined but not used [-Wunused-function] drivers/net/ethernet/intel/e1000e/netdev.c:6185:12: warning: ‘e1000_resume’ defined but not used [-Wunused-function] To fix this make the hooks to be available only when CONFIG_PM_SLEEP is set and remove CONFIG_PM wrapping from driver ops because this is already handled by SET_SYSTEM_SLEEP_PM_OPS() and SET_RUNTIME_PM_OPS().

2014-01-16ixgbe: Fix incorrect logic for fixed fiber eeprom writeDon Skidmore
In this code we wanted to set the bit in IXGBE_SFF_SOFT_RS_SELECT_MASK to the value in rs. So we really needed a logical or rather than an and, this patch makes that change.

2014-01-16ixgbevf: create function for all of ring initDon Skidmore
This patch creates new functions for ring initialization, ixgbevf_configure_tx_ring() and ixgbevf_configure_rx_ring(). The work done in these function previously was spread between several other functions and this change should hopefully lead to greater readability and make the code more like ixgbe. This patch also moves the placement of some older functions to avoid having to write prototypes. It also promotes a couple of debug messages to errors.

2014-01-16ixgbevf: Convert ring storage form pointer to an array to array of pointersDon Skidmore
This will change how we store rings arrays in the adapter sturct. We use to have a pointer to an array now we will be using an array of pointers. This will allow us to support multiple queues on muliple nodes at some point we would be able to reallocate the rings so that each is on a local node if needed.

2014-01-16ixgbevf: use pci drvdata correctly in ixgbevf_suspend()Wei Yongjun
We had set the pci driver-specific data in ixgbevf_probe() as a type of struct net_device, so we should use it as netdev in ixgbevf_suspend().

2014-01-16ixgbevf: set the disable state when ixgbevf_qv_disable is calledJacob Keller
The ixgbevf_qv_disable function used by CONFIG_NET_RX_BUSY_POLL is broken, because it does not properly set the IXGBEVF_QV_STATE_DISABLED bit, indicating that the q_vector should be disabled (and preventing future locks from obtaining the vector). This patch corrects the issue by setting the disable state.

2014-01-16ixgbe: reinit_locked() should be called with rtnl_lockJohn Fastabend
ixgbe_service_task() is calling ixgbe_reinit_locked() without the rtnl_lock being held. This is because it is being called from a worker thread and not a rtnl netlink or dcbnl path. Add rtnl_{un}lock() semantics. I found this during code review.
