[SCSI] libfc: add fc_frame_sid() and fc_frame_did() functions
To pave the way for eliminating exchanges from incoming requests, add simple inline fc_frame_sid() and fc_frame_did() functions which get the FC_IDs from the frame header. This can be almost as efficient as getting them from the sequence/exchange. Move ntohll, htonll, ntoh24 and hton24 to <scsi/fc_frame.h> since we need them there and that's included by <scsi/libfc.h> Signed-off-by: Joe Eykholt <jeykholt@cisco.com> Signed-off-by: Robert Love <robert.w.love@intel.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
