- Check for tcpdump availability before printing startup message
- Show 'Note: tcpdump not found, skipping concurrent count' when unavailable
- Prevents confusing message when tcpdump is not installed

- Add detailed error messages when tcpdump fails or produces no output
- Show tcpdump stderr output for debugging filter issues
- Return 0 instead of None when tcpdump finds 0 packets (so it's displayed)
- Handle SIGTERM return code properly (expected when terminating)
- Display tcpdump count even when 0 to help diagnose issues
- Add note when tcpdump counter is unavailable

- Run tcpdump concurrently with scapy to count data frames
- Use BPF filter (wlan[0] & 0x0C == 0x08) to filter data frames only
- Display comparison between scapy and tcpdump data frame counts
- Show capture ratio to identify if scapy is missing packets
- Add re import for regex parsing of tcpdump output

- Fix async subprocess.communicate() usage: await before unpacking tuple
Changed from: stderr = await proc.communicate()[1]
To: _, stderr = await proc.communicate()
- Remove snaplen parameter from sniff() calls (not supported for live interface capture)
- Update messages to reflect that full packets are captured for live capture
- Remove redundant proc.wait() calls after communicate()
