  Adds and deletes routing table entries.\r
  \r
  The Routes() function adds a route to or deletes a route from the routing table.\r
  Routes are determined by comparing the SubnetAddress with the destination IP\r
  address and arithmetically AND-ing it with the SubnetMask. The gateway address\r
  must be on the same subnet as the configured station address.\r
  The default route is added with SubnetAddress and SubnetMask both set to 0.0.0.0.\r
  The default route matches all destination IP addresses that do not match any\r
  other routes.\r
  A zero GatewayAddress is a nonroute. Packets are sent to the destination IP\r
  address if it can be found in the Address Resolution Protocol (ARP) cache or\r
  on the local subnet. One automatic nonroute entry will be inserted into the\r
  routing table for outgoing packets that are addressed to a local subnet\r
  (gateway address of 0.0.0.0).\r
  Each instance of the EFI UDPv4 Protocol has its own independent routing table.\r
  Instances of the EFI UDPv4 Protocol that use the default IP address will also\r
  have copies of the routing table provided by the EFI_IP4_CONFIG_PROTOCOL. These\r
  copies will be updated automatically whenever the IP driver reconfigures its\r
  instances; as a result, the previous modification to these copies will be lost.\r
