This leads the port net/py-libdnet to be broken:

--- fw-pf.lo ---
fw-pf.c:212:22: error: use of undeclared identifier 'DIOCGETRULE'
                        if (ioctl(fw->fd, DIOCGETRULE, &pcr) == 0 &&
                                          ^

That leads to:

net/scapy is used by parts of the kyua testsuite (when installed, anyway).
