NFC: Initial LLCP support
This patch is an initial implementation for the NFC Logical Link Control protocol. It's also known as NFC peer to peer mode. This is a basic implementation as it lacks SDP (services Discovery Protocol), frames aggregation support, and frame rejecion parsing. Follow up patches will implement those missing features. This code has been tested against a Nexus S phone implementing LLCP 1.0. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
