From 57be1f3f3ec1ccab6432615ca161c4c9ece2a2aa Mon Sep 17 00:00:00 2001 From: Hiren Tandel Date: Mon, 5 May 2014 19:43:31 +0900 Subject: NFC: Add RAW socket type support for SOCKPROTO_RAW This allows for a more generic NFC sniffing by using SOCKPROTO_RAW SOCK_RAW to read RAW NFC frames. This is for sniffing anything but LLCP (HCI, NCI, etc...).
