From: Vasu Dev <vasu.dev@xxxxxxxxx>
Removes no where used several inline functions prefixed with skb_*
and be16_to_cpu.
Moves fcoe module specific func prototypes to fcoe.c from libfcoe.h,
moved only need for build.
Adds fcoe module header file fcoe.h and then moves fcoe module
specific fcoe_percpu_s and fcoe_softc to fcoe.h from libfcoe.h.
Moves all defines from fcoe.c to fcoe.h since now fcoe module
has its own header file fcoe.h.
