    net: Pass optional SKB and SK arguments to dst_ops->{update_pmtu,redirect}() · 6700c270

    This will be used so that we can compose a full flow key.
    Even though we have a route in this context, we need more.  In the
    future the routes will be without destination address, source address,
    etc. keying.  One ipv4 route will cover entire subnets, etc.
    In this environment we have to have a way to possess persistent storage
    for redirects and PMTU information.  This persistent storage will exist
    in the FIB tables, and that's why we'll need to be able to rebuild a
    full lookup flow key here.  Using that flow key will do a fib_lookup()
    and create/update the persistent entry.
