Maybe the solution is to add a new option in Kconfig to define the
extra headers size the driver will need.  That option will increase
the headers.  I do not like that very much since it requires someone
know how big the value should be.  Could default it to 48 or 64
bytes and allow it to be edited.  It is not great solution since it
fixes the pxa168 driver but does not handle other drivers.

Take a look at how we define LL_MAX_HEADER in include/linux/netdevice.h
