It's a slightly unconventional way to specify TCP :)
Protocols have numbers (after all, *everything* has numbers when a computer
gets involved...), and TCP happens to be protocol number 6; UDP is protocol
number 17, and ICMP is protocol number 1.
See /etc/protocols on your own machine for more examples.
