According to section 8.3.2.2.1 of the XL710 datasheet, FLTSTAT indicates if RSS hashing was used (or flow director or nothing) to arrive at the flowid it is reporting. We need to check this before reporting the flowid and setting the rss type. Not checking this allows invalid flowids (0s) to be reported for some TCP traffic (it seems to mostly impact incoming connections). This leads to the inp flowid being 0, and egress traffic being unbalanced (going to tx queue 0, and NIC 0 of an lacp bundle).

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
