net 04/05: fib_rules: allow to delete local rule
commit d124356ce314fff22a047ea334379d5105b2d834

net: fib_rules: allow to delete local rule
Allow to delete the local rule and recreate it with a higher priority. This
can be used to force packets with a local destination out on the wire instead
of routing them to loopback. Additionally this patch allows to recreate rules
with a priority of 0.
Combined with the previous patch to allow oif classification, a socket can
be bound to the desired interface and packets routed to the wire like this:
# move local rule to lower priority
ip rule add pref 1000 lookup local
ip rule del pref 0
# route packets of sockets bound to eth0 to the wire independant
# of the destination address
ip rule add pref 100 oif eth0 lookup 100
ip route add default dev eth0 table 100
