* drivers/net: remove all references to obsolete Ethernet-HOWTOPaul Gortmaker2015-06-231-2/+0
| | | | | | | | | | | | | | | | | | 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 <paul.gortmaker@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>

|\| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Four minor merge conflicts: 1) qca_spi.c renamed the local variable used for the SPI device from spi_device to spi, meanwhile the spi_set_drvdata() call got moved further up in the probe function. 2) Two changes were both adding new members to codel params structure, and thus we had overlapping changes to the initializer function. 3) 'net' was making a fix to sk_release_kernel() which is completely removed in 'net-next'. 4) In net_namespace.c, the rtnl_net_fill() call for GET operations had the command value fixed, meanwhile 'net-next' adjusted the argument signature a bit. This also matches example merge resolutions posted by Stephen Rothwell over the past two days. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | Under heavy Rx load, observed that the Hw is updating the USED bit and it is not updating the received frame status to the BD control field. This could be lack of resources for processing the BDs at high data rates. Driver drops the frame associated with this BD but not clearing the USED bit.

| | | | | | | | | | | | | As accessing the peripheral registers need the clocks to be set, we have to enable them as soon as possible. Their configuration depend on the type of device used and determined by the DT compatible string. That lead to add another initialization function in the DT configuration structure.

As currently written, macb always ends up requesting a new tx_clk frequency in macb_handle_link_change. It is a waste of time to request a new tx_clk frequency if the link state hasn't changed, as the tx_clk will already be configured properly. Let's only request a new tx_clk clock frequency when necessary.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | macb and at91_ether drivers can be compiled as modules, but the at91_ether driver use some functions and variables defined in the macb one, thus creating a dependency on the macb driver. Since these drivers are sharing the same logic we can easily merge at91_ether into macb. In order to factorize common probing logic we've added an ->init() function to struct macb_config (the structure associated with the compatible string), and moved macb specific init code from macb_probe to macb_init.

* net/macb: remove useless calls of devm_free_irq()Cyrille Pitchen2014-12-151-15/+8
| | | | | | | | | | | Inside macb_probe(), when devm_request_irq() fails on queue q, there is no need to call devm_free_irq() on queues 0..q-1 because the managed device resources are released later when calling free_netdev(). Also removing devm_free_irq() call from macb_remove() for the same reason. Signed-off-by: Cyrille Pitchen <cyrille.pitchen@atmel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* net/macb: fix misplaced call of free_netdev() in macb_remove()Cyrille Pitchen2014-12-151-1/+1
| | | | | | | | | | | fix a bug introduced by the multiqueue support patch: "net/macb: add TX multiqueue support for gem" the "bp" pointer to the netdev private data was dereferenced and used after the associated memory had been freed by calling free_netdev().

They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes.
