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

2016-01-31T19:25:49+00:00

[ 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

2016-01-23T04:55:42+00:00

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.

Peter writes: USB: chipidea updates for v4.3-rc1 The main changes are adding several system interfaces for tuning performance, and each vendors can adjust them according to their design configurations. Others are tiny improvements, like more well siTD supports, USB_DEVICE_A_HNP_SUPPORT supports, etc.

Felipe writes: usb: patches for v4.3 merge window New support for Allwinne SoC on the MUSB driver has been added to the list of glue layers. MUSB also got support for building all DMA engines in one binary; this will be great for distros. DWC3 now has no trace of dev_dbg()/dev_vdbg() usage. We will rely solely on tracing to debug DWC3. There was also a fix for memory corruption with EP0 when maxpacket size transfers are > 512 bytes. Robert's EP capabilities flags is making EP selection a lot simpler. UDCs are now required to set these flags up when adding endpoints to the framework. Other than these, we have the usual set of miscelaneous cleanups and minor fixes. Signed-off-by: Felipe Balbi
