2016-04-20fm10k: Add support for bulk Tx cleanup & cleanup boolean logicAlexander Duyck
This patch enables bulk free in Tx cleanup for fm10k and cleans up the boolean logic in the polling routines for fm10k in the hopes of avoiding any mix-ups similar to what occurred with i40e and i40evf.

2016-04-20fm10k: remove debug-statistics supportJacob Keller
This change fixes an (ab)use of the ethtool stats API, which could result in corrupt memory or misleading stat output. The ethtool stats API is not robust enough to handle varying number of statistics due to how it requests the size and allocates memory. Remove the poorly conceived support originally added for extra debug statistics. In the future, a new stats API may open up the ability to display these statistics.

2016-04-20fm10k: add helper functions to set strings and data for ethtool statsJacob Keller
Reduce duplicate code and the amount of indentation by adding fm10k_add_stat_strings and fm10k_add_ethtool_stats functions which help add fm10k_stat structures to the ethtool stats callbacks. This helps increase ease of use for future stat additions, and increases code readability.

2016-04-16nfp: add async reconfiguration mechanismJakub Kicinski
Some callers of nfp_net_reconfig() are in atomic context so we used to busy wait for commands to complete. In worst case scenario that means locking up a core for up to 5 seconds when a command times out. Lets add a timer-based mechanism of asynchronously checking whether reconfiguration completed successfully for atomic callers to use. Non-atomic callers can now just sleep. The approach taken is quite simple because (1) synchronous reconfigurations always happen under RTNL (or before device is registered); (2) we can coalesce pending reconfigs. There is no need for request queues, timer which eventually takes a look at reconfiguration result to report errors is good enough.

Also remove the buffer length validation: (a) it's imprecise for static rx-offsets; (b) if firmware is buggy enough to DMA past the end of the buffer WARN_ON_ONCE() doesn't seem like a strong enough response. skb_put() will do the checking for us anyway.

2016-04-16stmmac: socfpga: remove extra call to socfpga_dwmac_setupDinh Nguyen
In the socfpga_dwmac_probe function, we have a call to socfpga_dwmac_setup, which is already called from socfpga_dwmac_init later in the probe function. Remove this extra call to socfpga_dwmac_setup. Also we should not be calling socfpga_dwmac_setup() directly without wrapping it around the proper reset assert/deasserts. That is because the socfpga_dwmac_setup() is setting up PHY modes in the system manager, and it is requires the EMAC's to be in reset during the PHY setup.

This adds support for W5200 chip. W5100 and W5200 have similar memory map although some of their offsets are different. The register access sequences between them are different but w5100 driver has abstraction layer for difference bus interface modes so it is easy to add W5200 support to w5100 and w5100-spi drivers.

2016-04-16net: w5100: enable to support sleepable register access interfaceAkinobu Mita
SPI transfer routines are callable only from contexts that can sleep. This adds ability to tell the core driver that the interface mode cannot access w5100 register on atomic contexts. In this case, workqueue and threaded irq are required. This also corrects timeout period waiting for command register to be automatically cleared because the latency of the register access with SPI transfer can be interfered by other contexts.

2016-04-16net: w5100: add ability to support other bus interfaceAkinobu Mita
The w5100 driver currently only supports direct and indirect bus interface mode which use MMIO space for accessing w5100 registers. In order to support SPI interface mode which is supported by W5100 chip, this makes the bus interface abstraction layer more generic so that separated w5100-spi driver can use w5100 driver as core module.

Replace deprecated create_singlethread_workqueue with alloc_ordered_workqueue. Work items include getting tx/rx frame sizes, resetting MPI processor, setting asic recovery bit so ordering seems necessary as only one work item should be in queue/executing at any given time, hence the use of alloc_ordered_workqueue.
