I mean something like this. You can see that "ip,tcp_src=80" gets
changed into just "ip", which gets installed:
blp@sigsegv:~/ovs/tutorial$ ovs-vsctl add-br br0
blp@sigsegv:~/ovs/tutorial$ ovs-ofctl add-flow br0
ip,tcp_src=80,actions=drop

details:

NXST_FLOW reply (xid=0x4):

idle_age=187, priority=0 actions=NORMAL
cookie=0x0, duration=9.804s, table=0, n_packets=0, n_bytes=0, idle_age=9,
ip actions=drop
blp@sigsegv:~/ovs/tutorial$
Is there better wording?
