I get a compilation error here. For me this code here works:

     if (/* rule->prtclType >= VIR_NWFILTER_RULE_PROTOCOL_NONE && */
         rule->prtclType <= VIR_NWFILTER_RULE_PROTOCOL_IPV6)
         return true;
What is the actual error you get ?

That constant exists in the header files

$ git grep RULE_PROTOCOL_NONE src/conf/nwfilter_conf.h
src/conf/nwfilter_conf.h:    VIR_NWFILTER_RULE_PROTOCOL_NONE = 0,

Related to evaluation of >= 0 on unsigned int always being true.
