/****************************************************************************
* Name: netdev_wifr_dev
* Name: netdev_sixlowpan_ioctl
*
* Description:
* Verify the struct iwreq and get the Wireless device.
* Perform 6loWPAN network device specific operations.
*
* Parameters:
* req - The argument of the ioctl cmd
* psock Socket structure
* dev Ethernet driver device structure
* cmd The ioctl command
* req The argument of the ioctl cmd
*
* Return:
* A pointer to the driver structure on success; NULL on failure.
* >=0 on success (positive non-zero values are cmd-specific)
* Negated errno returned on failure.
*
