net: cdc_ncm: avoid changing RX/TX buffers on MTU changes

2016-01-31T19:23:35Z

[ Upstream commit 1dfddff5fcd869fcab0c52fafae099dfa435a935 ] NCM buffer sizes are negotiated with the device independently of the network device MTU. The RX buffers are allocated by the usbnet framework based on the rx_urb_size value set by cdc_ncm. A single RX buffer can hold a number of MTU sized packets. The default usbnet change_mtu ndo only modifies rx_urb_size if it is equal to hard_mtu. And the cdc_ncm driver will set rx_urb_size and hard_mtu independently of each other, based on dwNtbInMaxSize and dwNtbOutMaxSize respectively. It was therefore assumed that usbnet_change_mtu() would never touch rx_urb_size. This failed to consider the case where dwNtbInMaxSize and dwNtbOutMaxSize happens to be equal. Fix by implementing an NCM specific change_mtu ndo, modifying the netdev MTU without touching the buffer size settings. Signed-off-by: Bjørn Mork Signed-off-by: David S.

USB: add quirk for devices with broken LPM

2016-01-23T04:54:10Z

commit ad87e03213b552a5c33d5e1e7a19a73768397010 upstream. Some USB device / host controller combinations seem to have problems with Link Power Management. For example, Steinar found that his xHCI controller wouldn't handle bandwidth calculations correctly for two video cards simultaneously when LPM was enabled, even though the bus had plenty of bandwidth available. This patch introduces a new quirk flag for devices that should remain disabled for LPM, and creates quirk entries for Steinar's devices. Signed-off-by: Alan Stern Reported-by: Steinar H.

usbnet: Fix tx_bytes statistic running backward in cdc_ncm

2015-03-29T19:06:45Z

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.

usbnet: Fix tx_packets stat for FLAG_MULTI_FRAME drivers

2015-03-29T19:06:43Z

Currently the usbnet core does not update the tx_packets statistic for drivers with FLAG_MULTI_PACKET and there is no hook in the TX completion path where they could do this. cdc_ncm and dependent drivers are bumping tx_packets stat on the transmit path while asix and sr9800 aren't updating it at all. 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.

Merge tag 'usb-for-v4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next

2015-03-24T21:57:49Z

Felipe writes: 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.
