A C program using GNU Automake for capturing and parsing 802.11 WiFi
frame headers in monitor mode. Designed to verify ESP32 monitor code
by comparing Linux vs ESP32 frame parsing.
Features:
- Monitor mode setup using libnl3
- Packet capture using libpcap
- 802.11 frame parsing (RA, TA, duration, retry flag)
- MAC address filtering (matches ESP32 filter behavior)
- Output format matches ESP32 debug logs for easy comparison
