2014-07-10usb: gadget: NCM: Stop RX TCP Bursts getting dropped.Jim Baxter
This fixes a problem with dropped packets over 16k CDC-NCM when the connection is being heavily used. The issue was that the extracted frames cloned from the received frame were consuming more memory than necessary resulting in the truesize being ~32KB instead of ~2KB, this meant there was a high chance of reaching the sk_rcvbuf limit.

2014-07-10usb: gadget: NCM: Add transmit multi-frame.Jim Baxter
This adds multi-frame support to the NCM NTB's for the gadget driver. This allows multiple network packets to be put inside a single USB NTB with a maximum size of 16kB. It has a time out of 300ms to ensure that smaller number of packets still maintain a normal latency. Also the .fp_index and .next_fp_index have been changed to .ndp_index and .next_ndp_index to match the latest CDC-NCM specification and help with maintenance. Results transmitting from gadget to host.

2014-07-10usb: gadget: f_fs: OS descriptors supportAndrzej Pietrasiewicz
Add support for OS descriptors. The new format of descriptors is used, because the "flags" field is required for extensions. os_count gives the number of OSDesc[] elements. The format of descriptors is given in include/uapi/linux/usb/functionfs.h. For extended properties descriptor the usb_ext_prop_desc structure covers only a part of a descriptor, because the wPropertyNameLength is unknown up front.

commit c63d2225e7be ("usb: gadget: pxa25x_udc: use devm_ functions") introduced the use of devm_gpio_request in this driver, but did not correctly include the header file declaring this function, which causes a build failure.

2014-06-30usb: gadget: net2280: Add support for PLX USB338XRicardo Ribalda Delgado
This patch adds support for the PLX USB3380 and USB3382. This driver is based on the driver from the manufacturer. Since USB338X is register compatible with NET2280, I thought that it would be better to include this hardware into net2280 driver. Manufacturer's driver only supported the USB33X, did not follow the Kernel Style and contain some trivial errors. This patch has tried to address this issues. This patch has only been tested on USB338x hardware, but the merge has been done trying to not affect the behaviour of NET2280.

Also, the unnecesary labels are removed and some labels are renamed to preserve ordering.
