           Summary: flow record for ICMP6 missing type and code values
    Classification: Unclassified
           Product: softflowd
           Version: -current
          Platform: amd64
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: softflowd
        AssignedTo: djm at mindrot.org
        ReportedBy: bugzilla at nishidaya.org

softflowd generates netflow v9 flow record for ICMP6 with dst port ==
0, while ICMP (IPv4) case dst port = type *256+code.

I know this feature is for CISCO compatibility (and v9 already has
ICMPTYPE but CISCO doesn't use it). Since current CISCO routers
generate flow record for ICMP6 with the same method (fill dst port with
type & code), I'm appreciate if Softflowd do the same.

softflowd.c around line 313 may be the place.
