stephen hemminger 8ef207d63f iph: use default get_stats
This driver keeps stats in net_device stats therefore it
does not need to define it's own get_stats hook.

Also, use standard format for net_device_ops (without &).

Ben Hutchings 9c412942a0 ipheth: Properly distinguish length and alignment in URBs and skbs
The USB protocol this driver implements appears to require 2 bytes of
padding in front of each received packet.  This used to be equal to
the value of NET_IP_ALIGN on x86, so the driver abused that constant
and mostly worked, but this is no longer the case.  The driver also
mixed up the URB and packet lengths, resulting in 2 bytes of junk at
the end of the skb.

Introduce a private constant for the 2 bytes of padding; fix this
confusion and check for the under-length case.

Dan Williams c9cedbba0f ipheth: remove incorrect devtype to WWAN
The 'wwan' devtype is meant for devices that require preconfiguration
and *every* time setup before the ethernet interface can be used, like
cellular modems which require a series of setup commands on serial ports
or other mechanisms before the ethernet interface will handle packets.

As ipheth only requires one-per-hotplug pairing setup with no
preconfiguration (like APN, phone #, etc) and the network interface is
usable at any time after that initial setup, remove the incorrect
devtype wwan.

Oliver Neukum c31fd6c25c usbnet: remove direct access to urb->status
USB drivers should not use urb->status directly because
it is scheduled to become a parameter. This does the conversion
for drivers/net/usb

Daniel Mack 997ea58eb9 USB: rename usb_buffer_alloc() and usb_buffer_free() users
For more clearance what the functions actually do,

  usb_buffer_alloc() is renamed to usb_alloc_coherent()
  usb_buffer_free()  is renamed to usb_free_coherent()

They should only be used in code which really needs DMA coherency.

All call sites have been changed accordingly, except for staging
drivers.

The calls to usb_free_buffer() dereference rx_urb and tx_urb in the
parameter list but those could be NULL.

Diego Giagio a19259c3d5 drivers/net/usb: Add new driver ipheth
Add new driver to use tethering with an iPhone device. After initial submission,
apply fixes to fit the new driver into the kernel standards.

There are still a couple of minor (almost cosmetic-level) issues, but the driver
is fully functional right now.
