The netmap_reset() function is meant to be called by the driver when they initialize (or re-initialize) a hardware ring. However, since the introduction of support for opening (in netmap mode) a subset of the available rings, netmap_reset() may be called multiple times on actively used rings, causing both kring and netmap ring to transition to an inconsistent state. This changes improves the situation by resetting all the indices fields of the kring to 0, as expected after the reinitialization of a hardware ring. PR: 252518 MFC after: 1 week

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.
