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.

USB drivers should not use urb->status directly because
it is scheduled to become a parameter. This does the conversion
for drivers/net/usb

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.

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.
