net: ethernet: wiznet: w5300: simplify getting .driver_data

2018-10-22T04:10:12+00:00

We should get 'driver_data' from 'struct device' directly. Going via platform_device is an unneeded step back and forth. Signed-off-by: Wolfram Sang Signed-off-by: David S. Miller

net: wiznet: fix return type of ndo_start_xmit function

2018-09-22T02:15:15+00:00

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t', which is a typedef for an enum type, so make sure the implementation in this driver has returns 'netdev_tx_t' value, and change the function return type to netdev_tx_t.

net: ethernet: wiznet: avoid format string exposure

2017-04-06T20:38:11+00:00

While unlikely, this makes sure any format strings in the device name can't exposure information via the resulting workqueue name. Signed-off-by: Kees Cook Signed-off-by: David S. Miller

drivers: net: generalize napi_complete_done()

2017-01-30T20:10:42+00:00

napi_complete_done() allows to opt-in for gro_flush_timeout, added back in linux-3.19, commit 3b47d30396ba ("net: gro: add a per device gro flush timer") This allows for more efficient GRO aggregation without sacrifying latencies. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

net: deprecate eth_change_mtu, remove usage

2016-10-13T13:36:57+00:00

With centralized MTU checking, there's nothing productive done by eth_change_mtu that isn't already done in dev_set_mtu, so mark it as deprecated and remove all usage of it in the kernel. All callers have been audited for calls to alloc_etherdev* or ether_setup directly, which means they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu prints out a netdev_warn about being deprecated, for the benefit of out-of-tree drivers that might be utilizing it. Of note, dvb_net.c actually had dev->mtu = 4096, while using eth_change_mtu, meaning that if you ever tried changing it's mtu, you couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set to 4096 to remedy that. v2: fix up lantiq_etop, missed breakage due to drive not compiling on x86 CC: netdev@vger.kernel.org Signed-off-by: Jarod Wilson Signed-off-by: David S.

treewide: remove redundant #include

2016-10-11T22:06:33+00:00

Kernel source files need not include explicitly because the top Makefile forces to include it with: -include $(srctree)/include/linux/kconfig.h This commit removes explicit includes except the following: * arch/s390/include/asm/facilities_src.h * tools/testing/radix-tree/linux/kernel.h These two are used for host programs.

net: ethernet: wiznet: Remove create_workqueue

2016-06-02T19:15:17+00:00

alloc_workqueue replaces deprecated create_workqueue(). A dedicated workqueue has been used since the workitems are involved in normal device operation. Workitems &priv->rx_work and &priv->tx_work, map to w5100_rx_work and w5100_tx_work respectively and are involved in receiving and transmitting packets. Forward progress under memory pressure is a requirement here. create_workqueue has been replaced with alloc_workqueue with max_active as 0 since there is no need for throttling the number of active work items. Since the driver may be used in memory reclaim path, WQ_MEM_RECLAIM has been set to guarantee forward progress. flush_workqueue is unnecessary since destroy_workqueue() itself calls drain_workqueue() which flushes repeatedly till the workqueue becomes empty. Hence the call to flush_workqueue() has been dropped. Signed-off-by: Bhaktipriya Shridhar Acked-by: Tejun Heo Signed-off-by: David S. Miller

net: w5100-spi: add support to specify MAC address by device tree

2016-05-16T17:55:49+00:00

This adds support to specify the MAC address by 'mac-address' or 'local-mac-address' properties in the device tree. These are common properties for the Ethernet controller. Signed-off-by: Akinobu Mita Cc: Mike Sinkovsky Cc: David S. Miller Signed-off-by: David S. Miller

net: w5100: increase TX timeout period

2016-05-16T17:55:49+00:00

This increases TX timeout period from one second to 5 seconds which is the default value if the driver doesn't explicitly set net_device->watchdog_timeo. The one second timeout is too short for W5100 with SPI interface mode which doesn't support burst READ/WRITE processing in the SPI transfer. If the packet is transmitted while RX packets are being received at a very high rate, the TX transmittion work in the workqueue is delayed and the watchdog timer is expired.

net: w5100: fix MAC filtering for W5500
