ESP8266 packet injection/sniffer example

This example project utilizes sniffer capabilities of ESP8266 to perform deauth attack. Minimum SDK requirement is 1.4.0. The communication between the victim and access point (AP) is traced by wifi_set_promiscuous_rx_cb while packet injection is performed by wifi_send_pkt_freedom. To use the example adjust the Makefile and change MAC addresses in user/user_main.c.
