CAIF generic protocol implementation. This layer is somewhat generic in order to be able to use and test it outside the Linux Kernel. cfctrl.c - CAIF control protocol layer cfdbgl.c - CAIF debug protocol layer cfdgml.c - CAIF datagram protocol layer cffrml.c - CAIF framing protocol layer cfmuxl.c - CAIF mux protocol layer cfrfml.c - CAIF remote file manager protocol layer cfserl.c - CAIF serial (fragmentation) protocol layer cfsrvl.c - CAIF generic service layer functions cfutill.c - CAIF utility protocol layer cfveil.c - CAIF AT protocol layer cfvidl.c - CAIF video protocol layer Signed-off-by: Sjur Braendeland <sjur.brandeland@stericsson.com> Signed-off-by: David S.
