The vmx driver is an example of an iflib driver that might report packets using non-contiguous descriptors (with unused descriptors either between received packets or between the fragments of a received packet), so this assertion needs to be removed. For such drivers, the freelist producer and consumer indexes don't relate directly to driver ring slots (the driver deals directly with freelist buffer indexes supplied by iflib during refill, and reports them with each fragment during packet reception), but do continue to be used by iflib for accounting, such as determining the number of ring slots that are refillable.

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.
