[Test case] - Run network-manager on a network supporting IPv6. - Check /var/log/syslog for <warn> messages from NetworkManager. [Regression Potential] This changes behavior for handling the MTU value for IPv6, which should be no higher than the device MTU. Since 0 is an invalid value for MTU anyway, this should not otherwise affect MTU handling for devices. Possible regressions from the change might include invalid (too high) set MTU for a device due to the failure to recognize cases where the MTU needs to be adjusted, leading to packet loss on IPv6. -- Network manager is sending out a lot of warnings about changing the MTU: Sep 25 14:13:03 desktop NetworkManager[703]: <warn> (wlan0): Lowering IPv6 MTU (1480) to match device MTU (1280) Sep 25 14:13:21 desktop NetworkManager[703]: <warn> (wlan0): Lowering IPv6 MTU (1480) to match device MTU (0) Sep 25 14:13:21 desktop NetworkManager[703]: <warn> (wlan0): IPv6 MTU (0) smaller than 1280, adjusting Sep 25 14:13:21 desktop NetworkManager[703]: <warn> (wlan0): Raising device MTU (0) to match IPv6 MTU (1280) Sep 25 14:13:29 desktop NetworkManager[703]: <warn> (wlan0): Lowering IPv6 MTU (1480) to match device MTU (1280) Lowering IPv6 MTU (1480) to match device MTU (1280) repeats about 16 times between the other messages (about 2 mins round).
