ETF Qdisc currently checks for a socket with SO_TXTIME socket option. If
either is not present, the packet is dropped. In the future commits, we
want other Qdiscs to add packet with launchtime to the ETF Qdisc. Also,
there are some packets (e.g. ICMP packets) which may not have a socket
associated with them.  So, add an option to skip this check.
