2016-11-17net: stmmac: replace if (netif_msg_type) by their netif_xxx counterpartLABBE Corentin1-28/+21
As sugested by Joe Perches, we could replace all if (netif_msg_type(priv)) dev_xxx(priv->devices, ...) by the simpler macro netif_xxx(priv, hw, priv->dev, ...) Signed-off-by: Corentin Labbe <clabbe.montjoie@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-11-17net: stmmac: replace all pr_xxx by their netdev_xxx counterpartLABBE Corentin2-95/+123
The stmmac driver use lots of pr_xxx functions to print information. This is bad since we cannot know which device logs the information. (moreover if two stmmac device are present) Furthermore, it seems that it assumes wrongly that all logs will always be subsequent by using a dev_xxx then some indented pr_xxx like this: kernel: sun7i-dwmac 1c50000.ethernet: no reset control found kernel: Ring mode enabled kernel: No HW DMA feature register supported kernel: Normal descriptors kernel: TX Checksum insertion supported So this patch replace all pr_xxx by their netdev_xxx counterpart. Excepts for some printing where netdev "cause" unpretty output like: sun7i-dwmac 1c50000.ethernet (unnamed net_device) (uninitialized): no reset control found In those case, I keep dev_xxx. In the same time I remove some "stmmac:" print since this will be a duplicate with that dev_xxx displays.

2016-11-17net/mlx4_en: remove napi_hash_del() callEric Dumazet1-4/+0
There is no need calling napi_hash_del()+synchronize_rcu() before calling netif_napi_del() netif_napi_del() does this already. Using napi_hash_del() in a driver is useful only when dealing with a batch of NAPI structures, so that a single synchronize_rcu() can be used. mlx4_en_deactivate_cq() is deactivating a single NAPI.

2016-11-16mlxsw: Invoke driver's init/fini methods only if definedVadim Pasternak1-5/+9
We are going to add a minimal driver on top of the mlxsw core infrastructure, which will be mainly used for hardware monitoring in Baseboard management controller (BMC) installations. Unlike the switch drivers (e.g., spectrum, switchx2), this driver does not initialize the ASIC and therefore doesn't need to implement the init() and fini() methods in its 'mlxsw_driver' struct.

2016-11-16mlxsw: Add bus capability flagVadim Pasternak3-0/+10
The mlxsw core infrastructure currently assumes that communication with the ASIC is always possible using Ethernet management datagrams (EMADs), but this is only possible when the PCI bus is used. The bus capability flag is added to indicate EMAD support and make core initialize EMAD communication only when it's set. Otherwise, register access is done using command interface.

2016-11-16net: netcp: replace IS_ERR_OR_NULL by IS_ERRJulia Lawall1-3/+3
knav_queue_open always returns an ERR_PTR value, never NULL. This can be confirmed by unfolding the function calls and conforms to the function's documentation. Thus, replace IS_ERR_OR_NULL by IS_ERR in error checks.

The netdev->real_num_rx_queues setting is only available if CONFIG_SYSFS is enabled, so we now get a build failure when that is turned off: netronome/nfp/nfp_net_common.c: In function 'nfp_net_ring_swap_enable': netronome/nfp/nfp_net_common.c:2489:18: error: 'struct net_device' has no member named 'real_num_rx_queues'; did you mean 'real_num_tx_queues'?

The GPIO support in the hardware allows for up to 16 GPIO pins, enumerated from 0 to 15.

2016-11-16amd-xgbe: Fix possible uninitialized variableLendacky, Thomas1-1/+1
The debugfs support in the driver uses a common routine to write the debugfs values. In this routine, if the input file position is non-zero then the write routine will not return an error and an output parameter will not have been set. Because an error isn't returned an uninitialized value will be written into a register. Fix the common write routine to return an error if the input file position is non-zero, which will propagate back to the caller.
