net: cosmetic: Fix var naming net <-> eth drivers

2015-04-18T17:11:33Z

Update the naming convention used in the network stack functions and variables that Ethernet drivers use to interact with it. This cleans up the temporary hacks that were added to this interface along with the DM support. This patch has a few remaining checkpatch.pl failures that would be out of the scope of this patch to fix (drivers that are in gross violation of checkpatch.pl).

net: cosmetic: Name ethaddr variables consistently

2015-04-18T17:11:32Z

Use "_ethaddr" at the end of variables and drop CamelCase. Make constant values actually 'const'. Signed-off-by: Joe Hershberger Acked-by: Simon Glass

usb: modify usb_gadget_handle_interrupts to take controller index

2015-04-14T03:48:11Z

Since we support multiple dwc3 controllers to be existent at the same time, in order to handle the interrupts of a particular dwc3 controller usb_gadget_handle_interrutps should take controller index as an argument. Hence the API of usb_gadget_handle_interrupts is modified to take controller index as an argument and made the corresponding changes to all the usb_gadget_handle_interrupts calls.

net: Add ethernet FCS length macro in net.h

2015-03-25T03:22:37Z

Some ethernet drivers use their own version of ethernet FCS length macro which is really common. We define ETH_FCS_LEN in net.h and replace those custom versions in various places. Signed-off-by: Bin Meng Acked-by: Joe Hershberger

lib: string: move strlcpy() to a common place

2014-12-11T20:18:41Z

Move strlcpy() definition from drivers/usb/gadget/ether.c to lib/string.c because it is a very useful function. Let's add the prototype to include/linux/string.h too. Signed-off-by: Masahiro Yamada Acked-by: Simon Glass

usb: gadget: ether set wMaxPacketSize

2013-10-20T21:42:39Z

set wMaxPacketSize for full speed descriptors fs_source_desc, fs_sink_desc to 64. Full-speed bulk endpoint can have a maximum packet size of 8, 16, 32, or 64 bytes, so choice 64. The hs_source_desc, hs_sink_desc, already have their wMaxPacketSize set to 512. That is the only legal value for high speed bulk endpoints. Strictly speaking, this patch is not needed because usb_ep_autoconfig will call ep_matches which will override wMaxPacketSize for BULK endpoints only with the size associated with the endpoint setup by the udc driver. But if you want to rely on this, you may as well combine the full speed descriptor with the high speed descriptor to minimize confusion. Signed-off-by: Troy Kisky

usb: gadget: Fix data aborts during USB ethernet boot

2013-09-24T15:51:34Z

As seen on GCC 4.6 Linaro compiler, control_req buffer is not aligned on 4 byte boundaray causing data aborts in eth_setup -> conf_buf during dhcp boot over usb_ether. Fix the issue my aligning control_req buffer using DEFINE_CACHE_ALIGN_BUFFER. Tested on am335x_evm platform (beaglebone). Applies on 2013.10-rc1 branch.
