0011 The "Communication CPU to Application CPU Interface" (CAIF) is a packet
0012 based connection-oriented MUX protocol developed by ST-Ericsson for use
0013 with its modems. It is accessed from user space as sockets (PF_CAIF).
0014
0015 Say Y (or M) here if you build for a phone product (e.g. Android or
0016 MeeGo) that uses CAIF as transport. If unsure say N.
0017
0018 If you select to build it as module then CAIF_NETDEV also needs to be
0019 built as a module. You will also need to say Y (or M) to any CAIF
0020 physical devices that your platform requires.
0021
0022 See Documentation/networking/caif for a further explanation on how to
0023 use and configure CAIF.

0039 Say Y if you will be using a CAIF based GPRS network device.
0040 This can be either built-in or a loadable module.
0041 If you select to build it as a built-in then the main CAIF device must
0042 also be a built-in.
0043 If unsure say Y.

0050 Say Y if you are using CAIF over USB CDC NCM.
0051 This can be either built-in or a loadable module.

0053 also be a built-in.
