When SOL_SOCKET options (e.g., SO_BINDTODEVICE via ping -I) hit ICMP sockets, icmp_{get,set}sockopt logged “Unrecognized ICMP option: 17” before fallback. Handle SOL_SOCKET explicitly by returning -ENOPROTOOPT so psock_* routes to the socket-level handler. Removes noisy logs without changing behavior (invalid devices still return -ENODEV).
