Great! Yes, please! The value and mask for "ip_frag" match field seems to be defined at the following. https://github.com/openvswitch/ovs/blob/master/include/openvswitch/flow.h#L49-L52 https://github.com/openvswitch/ovs/blob/master/lib/meta-flow.c#L2199-L2211 According to the above, I guess the constants should be like: FLOW_NW_FRAG_ANY = 1 << 0 // Set for any IP frag. FLOW_NW_FRAG_LATER = 1 << 1 // Set for IP frag with nonzero offset. FLOW_NW_FRAG_MASK = FLOW_NW_FRAG_ANY | FLOW_NW_FRAG_LATER // legend: (value, mask) NXM_IP_FRAG_NO = (0, FLOW_NW_FRAG_MASK)) NXM_IP_FRAG_FIRST = (FLOW_NW_FRAG_ANY, FLOW_NW_FRAG_MASK) NXM_IP_FRAG_LATER = (FLOW_NW_FRAG_MASK, FLOW_NW_FRAG_MASK) ...(snip) Thanks, Iwase > > > > > ------------------------------------------------------------------------------ > Check out the vibrant tech community on one of the world's most > engaging tech sites, SlashDot.org! http://sdm.link/slashdot > > > > _______________________________________________ > Ryu-devel mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/ryu-devel > ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Ryu-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/ryu-devel
