A NCI virtual device can be made to simulate a NCI device in user space. Using the virtual NCI device, The NCI module and application can be validated. This driver supports to communicate between the virtual NCI device and NCI module. To test the basic features of NCI module, selftest for nci is added. Test cases consist of making the virtual NCI device on/off and controlling the device's polling for NCI1.0 and NCI2.0 version.
1/2 is the Virtual NCI device driver. 2/2 is the NCI selftest suite
v3: 1/2 - change the Kconfig help comment. - remove the mutex init code. - remove the unnecessary mutex(nci_send_mutex). - remove the full_txbuff. - add the code to release skb at error case. - refactor some code. v2: 1/2 - change the permission of the Virtual NCI device. - add the ioctl to find the nci device index. 2/2 - add the NCI selftest suite.
