It's already available. Possibly it could use some improvement for
double-ended ranges:
blp@sigabrt:~/nicira/ovs/_build(0)$ echo 'ip4 && 1000 <= tcp.src <= 1999' |
tests/ovstest test-ovn expr-to-flows
tcp,tp_src=1001
tcp,tp_src=0x7c0/0xfff8
tcp,tp_src=1999
tcp,tp_src=1998
tcp,tp_src=0x7cc/0xfffe
tcp,tp_src=0x3ea/0xfffe
tcp,tp_src=0x700/0xff80
tcp,tp_src=0x780/0xffc0
tcp,tp_src=1000
tcp,tp_src=0x3ec/0xfffc
tcp,tp_src=0x600/0xff00
tcp,tp_src=0x400/0xfe00
tcp,tp_src=0x7c8/0xfffc
tcp,tp_src=0x3f0/0xfff0
