Replace init_timer_deferrable with setup_deferrable_timer to simplify the source code. Signed-off-by: Zhu Yanjun Signed-off-by: David S. Miller

forcedeth: remove unnecessary carrier status check

2017-05-04T14:57:41+00:00

Since netif_carrier_on() will do nothing if device's carrier is already on, so it's unnecessary to do carrier status check. It's the same for netif_carrier_off(). Signed-off-by: Zhu Yanjun Signed-off-by: David S. Miller

forcedeth: Remove return from a void function

2017-02-23T15:55:07+00:00

In a void function, it is not necessary to append a return statement in it. Signed-off-by: Zhu Yanjun Signed-off-by: David S. Miller

net: nvidia: forcedeth: use new api ethtool_{get|set}_link_ksettings

2017-02-17T16:05:33+00:00

The ethtool api {get|set}_settings is deprecated. We move this driver to new api {get|set}_link_ksettings. As I don't have the hardware, I'd be very pleased if someone may test this patch. Signed-off-by: Philippe Reynes 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: make ndo_get_stats64 a void function

2017-01-08T22:51:44+00:00

The network device operation for reading statistics is only called in one place, and it ignores the return value. Having a structure return value is potentially confusing because some future driver could incorrectly assume that the return value was used. Fix all drivers with ndo_get_stats64 to have a void function. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

forcedeth: Use setup_timer()

2016-02-25T21:51:05+00:00

Convert a call to init_timer and accompanying intializations of the timer's data and function fields to a call to setup_timer. The Coccinelle semantic patch that fixes this problem is as follows: // @@ expression t,f,d; @@ -init_timer(&t); +setup_timer(&t,f,d); -t.data = d; -t.function = f; // Signed-off-by: Amitoj Kaur Chawla Signed-off-by: David S.

forcedeth: fix unilateral interrupt disabling in netpoll path

2015-10-28T02:45:23+00:00

Forcedeth currently uses disable_irq_lockdep and enable_irq_lockdep, which in some configurations simply calls local_irq_disable. This causes errant warnings in the netpoll path as in netpoll_send_skb_on_dev, where we disable irqs using local_irq_save, leading to the following warning: WARNING: at net/core/netpoll.c:352 netpoll_send_skb_on_dev+0x243/0x250() (Not tainted) Hardware name: netpoll_send_skb_on_dev(): eth0 enabled interrupts in poll (nv_start_xmit_optimized+0x0/0x860 [forcedeth]) Modules linked in: netconsole(+) configfs ipv6 iptable_filter ip_tables ppdev parport_pc parport sg microcode serio_raw edac_core edac_mce_amd k8temp snd_hda_codec_realtek snd_hda_codec_generic forcedeth snd_hda_intel snd_hda_codec snd_hwdep snd_seq snd_seq_device snd_pcm snd_timer snd soundcore snd_page_alloc i2c_nforce2 i2c_core shpchp ext4 jbd2 mbcache sr_mod cdrom sd_mod crc_t10dif pata_amd ata_generic pata_acpi sata_nv dm_mirror dm_region_hash dm_log dm_mod [last unloaded: scsi_wait_scan] Pid: 1940, comm: modprobe Not tainted 2.6.32-573.7.1.el6.x86_64.debug #1 Call Trace: [] ? warn_slowpath_common+0x91/0xe0 [] ? warn_slowpath_fmt+0x46/0x60 [] ? nv_start_xmit_optimized+0x0/0x860 [forcedeth] [] ? netpoll_send_skb_on_dev+0x243/0x250 [] ? netpoll_send_udp+0x229/0x270 [] ? write_msg+0x39/0x110 [netconsole] [] ? write_msg+0xbb/0x110 [netconsole] [] ? __call_console_drivers+0x75/0x90 [] ? _call_console_drivers+0x4a/0x80 [] ? release_console_sem+0xe5/0x250 [] ? register_console+0x190/0x3e0 [] ? init_netconsole+0x1a6/0x216 [netconsole] [] ? init_netconsole+0x0/0x216 [netconsole] [] ? do_one_initcall+0xc0/0x280 [] ? sys_init_module+0xe3/0x260 [] ? system_call_fastpath+0x16/0x1b ---[ end trace f349c7af88e6a6d5 ]--- console [netcon0] enabled netconsole: network logging started Fix it by modifying the forcedeth code to use disable_irq_nosync_lockdep_irqsavedisable_irq_nosync_lockdep_irqsave instead, which saves and restores irq state properly.

drivers/net: remove all references to obsolete Ethernet-HOWTO

2015-06-23T13:50:35+00:00

This howto made sense in the 1990s when users had to manually configure ISA cards with jumpers or vendor utilities, but with the implementation of PCI it became increasingly less and less relevant, to the point where it has been well over a decade since I last updated it. And there is no value in anyone else taking over updating it either. However the references to it continue to spread as boiler plate text from one Kconfig file into the next. We are not doing end users any favours by pointing them at this old document, so lets kill it with fire, once and for all, to hopefully stop any further spread. No code is changed in this commit, just Kconfig help text. Signed-off-by: Paul Gortmaker Signed-off-by: David S. Miller
