net ipv4: Decouple ipv4 interface parameters from binary sysctl numbers
Stop using the binary sysctl enumeartion in sysctl.h as an index into a per interface array. This leads to unnecessary binary sysctl number allocation, and a fragility in data structure and implementation because of unnecessary coupling. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>
