[PATCH net-next 0/2] bareudp: Remove unused code from header file

[Guillaume Nault]

Stop exporting unused functions and structures in bareudp.h. The only
piece of bareudp.h that is actually used is netif_is_bareudp(). The
rest can be moved to bareudp.c or even dropped entirely.

  bareudp: Remove bareudp_dev_create()
  bareudp: Move definition of struct bareudp_conf to bareudp.c

[PATCH net-next 2/2] bareudp: Move definition of struct bareudp_conf to bareudp.c

[Guillaume Nault]

This structure is used only in bareudp.c.

While there, adjust include files: we need netdevice.h, not skbuff.h.
