Brennan Ashton a952d5c32a Default device net config enables ip forwarding ...

The Linux kernel is inconsistent about how devconf is configured for new
network namespaces between ipv4 and ipv6. The behavior can also be
controlled via net.core.devconf_inherit_init_net in Linux 5.1+ so make
sure to enable forwarding on all and default for both ipv6 and ipv4.

This issue first came up testing on a yocto kernel that had this patch:
 ipv4: net namespace does not inherit network configurations
