[ Upstream commit bd4a816752bab609dd6d65ae021387beb9e2ddbd ]
Lorenzo points out that we effectively clear all unknown flags from PIO when copying them to userspace in the netlink RTM_NEWPREFIX notification.
We could fix this one at a time as new flags are defined, or in one fell swoop - I choose the latter.
We could either define 6 new reserved flags (reserved1..6) and handle them individually (and rename them as new flags are defined), or we could simply copy the entire unmodified byte over - I choose the latter.
This unfortunately requires some anonymous union/struct magic, so we add a static assert on the struct size for a little extra safety.
