usbnet: fix alignment for frames with no ethernet header

2017-12-07T19:32:30+00:00

The qmi_wwan minidriver support a 'raw-ip' mode where frames are
received without any ethernet header. This causes alignment issues
because the skbs allocated by usbnet are "IP aligned".

Fix by allowing minidrivers to disable the additional alignment
offset. This is implemented using a per-device flag, since the same
minidriver also supports 'ethernet' mode.

USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02+00:00

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Update the drivers/usb/ and include/linux/usb* files with the correct
SPDX license identifier based on the license text in the file itself.
The SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.

This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

cdc-ether: divorce initialisation with a filter reset and a generic method

2017-05-23T15:01:28+00:00

Some devices need their multicast filter reset but others are crashed by that.
So the methods need to be separated.

net: usbnet: support 64bit stats

2017-04-04T02:09:40+00:00

Add support for the net stats64 counters to the usbnet core. With that
in place put the hooks into every usbnet driver to use it.

This is a strait forward addition of 64bit counters for RX and TX packet
and byte counts. It is done in the same style as for the other net drivers
that support stats64. Note that the other stats fields remain as 32bit
sized values (error counts, etc).

The motivation to add this is that it is not particularly difficult to
get the RX and TX byte counts to wrap on 32bit platforms.

net: usb: usbnet: add new api ethtool_{get|set}_link_ksettings

2017-03-21T23:03:58+00:00

The ethtool api {get|set}_settings is deprecated.
We add the new api {get|set}_link_ksettings to this driver.

As I don't have the hardware, I'd be very pleased if
someone may test this patch.

usbnet: Fix tx_bytes statistic running backward in cdc_ncm

2015-03-29T19:06:45+00:00

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

2015-03-29T19:06:43+00:00

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.

cdc_subset: deal with a device that needs reset for timeout

This device needs to be reset to recover from a timeout.
Unfortunately this can be handled only at the level of
