Dear forum,

Does QNX 6.5 support the mbuf_tags API as described in http://portal.acm.org/citation.cfm?id=1250985? It is not 
mentioned in the documentation, but matching prototypes can be found in sys\mbuf.h. 

If yes, any restrictions on type of networking stack (v4, v4-hc, v6-hc) this API may be used with?

Does the QNX packet filter (PF) propagate packet tags done by its rules on egress packets to the mbuf_tags information 
in packet mbufs?

Thanks!
Max
