- Add comprehensive VL1 (ZeroTier protocol) fragmentation metrics: * Track fragmented packets, fragments, reassembly failures * Monitor fragment ordering issues and duplicates * Histogram for fragments per packet distribution - Add VL2 (TAP/Ethernet) fragmentation metrics for virtual ethernet interfaces: * Track oversized frames from TAP devices * Monitor frames that would fragment or drop * Histogram for frame size distribution with common MTU buckets - Integration across all TAP implementations (Linux, Mac, BSD, Windows) This allows monitoring of fragmentation patterns for nodes participating as members in ZeroTier networks, helping identify MTU mismatches and optimize virtual ethernet performance.
