usbnet: Fix tx_bytes statistic running backward in cdc_ncm 2015-03-29T19:06:45+00:00 Ben Hutchings ben.hutchings@codethink.co.uk 2015-03-25T20:41:33+00:00 7a1e890e2168e33fb62d84528e996b8b4b478fea cdc_ncm disagrees with usbnet about how much framing overhead should be counted in the tx_bytes statistics, and tries 'fix' this by decrementing tx_bytes on the transmit path. But statistics must never be decremented except due to roll-over; this will thoroughly confuse user-space. Also, tx_bytes is only incremented by usbnet in the completion path. Fix this by requiring drivers that set FLAG_MULTI_FRAME to set a tx_bytes delta along with the tx_packets count.

Add a packet count in struct skb_data so these drivers can fill it in, initialise it to 1 for other drivers, and add the packet count to the tx_packets statistic on completion.

usb: patches for v4.1 merge window

As usual, a big pile of commits. This time a total
of 111 non-merge commits.

Other than the usual set of cleanups and non-critical
fixes, we have some interesting work for AM335x's MUSB
babble recovery. Now that takes a lot less time and we
don't have to Reset MUSB all the time.

The printer gadget has been converted to configfs interface
and the atmel udc has learned suspend/resume with wakeup.
