The current iteration of IPv6 support requires explicit fields to be set
in addition to not properly support the actual IPv6 addresses properly.
With this change, make it so that the ipv6() bare option is usable to
create wildcarded flows to match broad swaths of ipv6 traffic.

nit: Perhaps one blank line is enough

...

The nit above notwithstanding, this patch looks good to me.

Sure - dropped.
