Revert "cdc_subset: deal with a device that needs reset for timeout"

2014-07-30T15:56:23Z

This reverts commit 20fbe3ae990fd54fc7d1f889d61958bc8b38f254. As reported by Stephen Rothwell, it causes compile failures in certain configurations: drivers/net/usb/cdc_subset.c:360:15: error: 'dummy_prereset' undeclared here (not in a function) .pre_reset = dummy_prereset, ^ drivers/net/usb/cdc_subset.c:361:16: error: 'dummy_postreset' undeclared here (not in a function) .post_reset = dummy_postreset, ^ Reported-by: Stephen Rothwell Acked-by: David Miller Cc: Oliver Neukum Signed-off-by: Linus Torvalds

cdc-ether: clean packet filter upon probe

2014-07-29T19:22:15Z

There are devices that don't do reset all the way. So the packet filter should be set to a sane initial value. Failure to do so leads to intermittent failures of DHCP on some systems under some conditions. Signed-off-by: Oliver Neukum Signed-off-by: David S. Miller

cdc_subset: deal with a device that needs reset for timeout

2014-07-29T19:22:15Z

This device needs to be reset to recover from a timeout. Unfortunately this can be handled only at the level of the subdrivers. Signed-off-by: Oliver Neukum Signed-off-by: David S. Miller

r8152: fix the checking of the usb speed

2014-07-25T06:37:36Z

When the usb speed of the RTL8152 is not high speed, the USB_DEV_STAT[2:1] should be equal to [0 1]. That is, the STAT_SPEED_FULL should be equal to 2. There is a easy way to check the usb speed by the speed field of the struct usb_device. Use it to replace the original metheod.

net: huawei_cdc_ncm: add "subclass 3" devices

2014-07-17T23:49:50Z

Huawei's usage of the subclass and protocol fields is not 100% clear to us, but there appears to be a very strict system. A device with the "shared" device ID 12d1:1506 and this NCM function was recently reported (showing only default altsetting): Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 1 bAlternateSetting 0 bNumEndpoints 1 bInterfaceClass 255 Vendor Specific Class bInterfaceSubClass 3 bInterfaceProtocol 22 iInterface 8 CDC Network Control Model (NCM) ** UNRECOGNIZED: 05 24 00 10 01 ** UNRECOGNIZED: 06 24 1a 00 01 1f ** UNRECOGNIZED: 0c 24 1b 00 01 00 04 10 14 dc 05 20 ** UNRECOGNIZED: 0d 24 0f 0a 0f 00 00 00 ea 05 03 00 01 ** UNRECOGNIZED: 05 24 06 01 01 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x85 EP 5 IN bmAttributes 3 Transfer Type Interrupt Synch Type None Usage Type Data wMaxPacketSize 0x0010 1x 16 bytes bInterval 9 Cc: Enrico Mioso Signed-off-by: Bjørn Mork Signed-off-by: David S.

hso: fix deadlock when receiving bursts of data

2014-07-15T02:27:34Z

When the module sends bursts of data, sometimes a deadlock happens in the hso driver when the tty buffer doesn't get the chance to be flushed quickly enough. Remove the endless while loop in function put_rxbuf_data() which is called by the urb completion handler. If there isn't enough room in the tty buffer, discards all the data received in the URB.

The workqueue "retry_unthrottle_workqueue" is not scheduled anywhere in the code. So, remove it. Signed-off-by: Olivier Sobrie Signed-off-by: David S. Miller

r8152: fix r8152_csum_workaround function

2014-07-11T21:51:21Z

The transport offset of the IPv4 packet should be fixed and wouldn't be out of the hw limitation, so the r8152_csum_workaround() should be used for IPv6 packets. Signed-off-by: Hayes Wang Signed-off-by: David S. Miller

usbnet: smsc95xx: add reset_resume function with reset operation

2014-07-10T07:42:57Z

The smsc95xx needs to resume with reset operation. Otherwise it causes system hang by network error like below after resume. This case appears on odroid u3 board.
