 Known Issues:
+  * On certain systems the IPv6 rt match module (-m rt) is not available, causing Kura to fail when applying IPv6 mangle table rules related to Routing Header Type 0 filtering.
+    When this occurs, IPv6 Routing Header Type 0 packets will not be explicitly dropped on affected systems.
   * During a wifi scan, some access points with the WPA/WPA2 wifi security are recognized as WPA.
   * On devices with Ubuntu 20.04, the DHCP server provided by isc-dhcp-server may not assign an IP address to the clients. Use dnsmasq instead.
   * Different GNSS Type retrieved from different Position Providers (see #5409 for details)
