12. PHONET function
===================
The function is provided by usb_f_phonet.ko module.
Function-specific configfs interface
------------------------------------
The function name to use when creating the function directory is "phonet".
The PHONET function provides just one attribute in its function directory:
ifname - network device interface name associated with this
function instance
Testing the PHONET function
---------------------------
It is not possible to test the SOCK_STREAM protocol without a specific piece
of hardware, so only SOCK_DGRAM has been tested. For the latter to work,
in the past I had to apply the patch mentioned here:
http://www.spinics.net/lists/linux-usb/msg85689.html
These tools are required:
git://git.gitorious.org/meego-cellular/phonet-utils.git
On the host:
$ ./phonet -a 0x10 -i usbpn0
$ ./pnroute add 0x6c usbpn0
$./pnroute add 0x10 usbpn0
$ ifconfig usbpn0 up
On the device:
$ ./phonet -a 0x6c -i upnlink0
$ ./pnroute add 0x10 upnlink0
$ ifconfig upnlink0 up
Then a test program can be used:
http://www.spinics.net/lists/linux-usb/msg85690.html
On the device:
$ ./pnxmit -a 0x6c -r
On the host:
$ ./pnxmit -a 0x10 -s 0x6c
As a result some data should be sent from host to device.
Then the other way round:
On the host:
$ ./pnxmit -a 0x10 -r
On the device:
$ ./pnxmit -a 0x6c -s 0x10
