Subject: [PATCH] Remove unused struct prf_ra;  dead since 2017
 sys/netinet/icmp6.h r1.45

    Get rid of ICMPV6CTL_ND6_DRLIST and ICMPV6CTL_ND6_PRLIST sysctls
    With this we can also get rid of in6_prefix and in6_defrouter. They
    are meaningless, the kernel no longer tracks this information.

Outside of _KERNEL, but nothing in base uses it, either.
codesearch.debian.net seems to agree.

OK mvs claudio bluhm
