When wlan0 is the primary data interface (WiFi-only deployment), changing
its MAC via SIOCSIFHWADDR drops the AP association and puts all AF_PACKET
sockets into ENETDOWN permanently until wpa_supplicant re-associates.
- _apply_profile: skip set_mac if _eth_iface is a WiFi interface
- _apply_profile: skip WiFi set_mac if _wifi_iface == _eth_iface (same card)
- stop: mirror the same skip logic for MAC restoration
DHCP hostname + TCP stack tuning still applied for blending on WiFi-only nodes.
