usb/kaweth: use GFP_ATOMIC under spin_lock in usb_start_wait_urb()

2015-01-12T21:42:49+00:00

Commit e4c7f259c5be ("USB: kaweth.c: use GFP_ATOMIC under spin_lock")
makes sure that kaweth_internal_control_msg() allocates memory with GFP_ATOMIC,
but kaweth_internal_control_msg() also calls usb_start_wait_urb()
that still allocates memory with GFP_NOIO.

The patch fixes usb_start_wait_urb() as well.

r8152: support ndo_features_check

2015-01-06T18:29:13+00:00

Support ndo_features_check to avoid:
 - the transport offset is more than the hw limitation when using hw checksum.
 - the skb->len of a GSO packet is more than the limitation.

qmi_wwan: Set random MAC on devices with buggy fw

2015-01-02T21:41:47+00:00

Some buggy firmwares export an incorrect MAC address (00:a0:c6:00:00:00). This
makes for example checking devices for random MAC addresses tricky, and you
might end up with multiple network interfaces with the same address.

This patch tries to fix, or at least improve, the situation by setting the MAC
address of devices with this firmware bug to a random address. I tested the
patch with two devices that has this firmware bug (Huawei E398 and E392), and
network traffic worked fine after changing the address.

r8152: redefine REALTEK_USB_DEVICE

2014-12-09T18:41:24+00:00

Redefine REALTEK_USB_DEVICE for the desired USB interface for probe().
There are three USB interfaces for the device. USB_CLASS_COMM and
USB_CLASS_CDC_DATA are for ECM mode (config #2). USB_CLASS_VENDOR_SPEC
is for the vendor mode (config #1). However, we are not interesting
in USB_CLASS_CDC_DATA for probe(), so redefine REALTEK_USB_DEVICE
to ignore the USB interface class of USB_CLASS_CDC_DATA.

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

2014-11-22T03:28:24+00:00

Conflicts:
	drivers/net/ieee802154/fakehard.c

A bug fix went into 'net' for ieee802154/fakehard.c, which is removed
in 'net-next'.

Add build fix into the merge from Stephen Rothwell in openvswitch, the
logging macros take a new initial 'log' argument, a new call was added
in 'net' so when we merge that in here we have to explicitly add the
new 'log' arg to it else the build fails.

net: USB: Deletion of unnecessary checks before the function call "kfree"

2014-11-21T20:16:10+00:00

The kfree() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

r8152: adjust rtl_start_rx

2014-11-21T19:52:57+00:00

If there is a error for r8152_submit_rx(), add the remaining rx
buffers to the list. Then the remaining rx buffers could be
submitted later.

r8152: adjust r8152_submit_rx

2014-11-21T19:52:57+00:00

The behavior of handling the returned status from r8152_submit_rx()
is almost same, so let r8152_submit_rx() deal with the error
directly. This could avoid the duplicate code.

vlan: kill vlan_put_tag helper

2014-11-21T19:20:17+00:00

Since both tx and rx paths work with skb->vlan_tci, there's no need for
this function anymore. Switch users directly to __vlan_hwaccel_put_tag.
