[SCSI] fcoe: cleans up libfcoe.h and adds fcoe.h for fcoe module
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. [jejb: removed EXPORT_SYMBOL_GPL(fcoe_fc_crc) which caused a section mismatch] Signed-off-by: Vasu Dev <vasu.dev@intel.com> Signed-off-by: Robert Love <robert.w.love@intel.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
