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

2015-06-23T13:50:35Z

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

Merge branch 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild

2015-02-19T18:36:45Z

Pull kconfig updates from Michal Marek: "Yann E Morin was supposed to take over kconfig maintainership, but this hasn't happened. So I'm sending a few kconfig patches that I collected: - Fix for missing va_end in kconfig - merge_config.sh displays used if given too few arguments - s/boolean/bool/ in Kconfig files for consistency, with the plan to only support bool in the future" * 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: kconfig: use va_end to match corresponding va_start merge_config.sh: Display usage if given too few arguments kconfig: use bool instead of boolean for type definition attributes

drivers: net: cpsw: make cpsw_ale.c a module to allow re-use on Keystone

2015-02-01T01:33:07Z

NetCP on Keystone has cpsw ale function similar to other TI SoCs and this driver is re-used. To allow both ti cpsw and keystone netcp to re-use the driver, convert the cpsw ale to a module and configure it through Kconfig option CONFIG_TI_CPSW_ALE. Currently it is statically linked to both TI CPSW and NetCP and this causes issues when the above drivers are built as dynamic modules. This patch addresses this issue While at it, fix the Makefile and code to build both netcp_core and netcp_ethss as dynamic modules. This is needed to support arm allmodconfig. This also requires exporting of API calls provided by netcp_core so that both the above can be dynamic modules.

net: netcp: remove unused kconfig option and code

2015-01-28T01:19:18Z

Currently CPTS is built into the netcp driver even though there is no call out to the CPTS driver. This patch removes the dependency in Kconfig and remove cpts.o from the Makefile for NetCP. Signed-off-by: Murali Karicheri Signed-off-by: David S. Miller

net: netcp: Add Keystone NetCP core ethernet driver

2015-01-19T20:07:39Z

The network coprocessor (NetCP) is a hardware accelerator available in Keystone SoCs that processes Ethernet packets. NetCP consists of following hardware components 1 Gigabit Ethernet (GbE) subsystem with a Ethernet switch sub-module to send and receive packets. 2 Packet Accelerator (PA) module to perform packet classification operations such as header matching, and packet modification operations such as checksum generation. 3 Security Accelerator(SA) capable of performing IPSec operations on ingress/egress packets. 4 An optional 10 Gigabit Ethernet Subsystem (XGbE) which includes a 3-port Ethernet switch sub-module capable of 10Gb/s and 1Gb/s rates per Ethernet port. 5 Packet DMA and Queue Management Subsystem (QMSS) to enqueue and dequeue packets and DMA the packets between memory and NetCP hardware components described above. NetCP core driver make use of the Keystone Navigator driver API to allocate DMA channel for the Ethenet device and to handle packet queue/de-queue, Please refer API's in include/linux/soc/ti/knav_dma.h and drivers/soc/ti/knav_qmss.h for details. NetCP driver consists of NetCP core driver and at a minimum Gigabit Ethernet (GBE) module (1) driver to implement the Network device function. Other modules (2,3) can be optionally added to achieve supported hardware acceleration function. The initial version of the driver include NetCP core driver and GBE driver modules. Please refer Documentation/devicetree/bindings/net/keystone-netcp.txt for design of the driver.
