    ipv4: Add FIB nexthop exceptions. · 4895c771
    David S. Miller authored
    In a regime where we have subnetted route entries, we need a way to
    store persistent storage about destination specific learned values
    such as redirects and PMTU values.
    
    This is implemented here via nexthop exceptions.
    
    The initial implementation is a 2048 entry hash table with relaiming
    starting at chain length 5.  A more sophisticated scheme can be
    devised if that proves necessary.
