2011-04-12caif: Don't resend if dev_queue_xmit fails.Sjur Brændeland1-6/+1
If CAIF Link Layer returns an error, we no longer try to re-build the CAIF packet and resend it. Instead, we simply return any transmission errors to the socket client. Signed-off-by: Sjur Brændeland <sjur.brandeland@stericsson.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-03-31net-caif: add CAIF core protocol stackSjur Braendeland1-0/+115
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.
