Code that sets IPv6 MTU can unintentionally act on IPv4 addresses
100%
Description
Related to https://redmine.pfsense.org/issues/11855
The patch on that issue adds a check for the address being IPv6 to the second half, but not to the loop.
Nov 16 21:50:26 ldex-fw2 php[386]: rc.bootup: The command '/sbin/route change -6 -mtu '9000' '192.168.101.0/24' '192.168.9.1'' returned exit code '71', the output was 'route: 192.168.101.0: Name does not resolve'
This is causing the boot up to stick on "Configuring VLAN interfaces..." for an extended period of time. I am able to reproduce using the config of a customer who is hitting this issue. I have made a patch that adds the additional check in and fixes the issue. I will submit a merge request for review shortly.
