35 Add or remove a route entry in the IP route table associated\r
36 with this TCP instance.\r
37\r
38Arguments:\r
39\r
40 Tcb - Pointer to the TCP_CB of this TCP instance.\r
41 RouteInfo - Pointer to the route info to be processed.\r
42\r
43Returns:\r
44\r
45 EFI_SUCCESS - The operation completed successfully.\r
46 EFI_NOT_STARTED - The driver instance has not been started.\r
47 EFI_NO_MAPPING - When using the default address, configuration(DHCP,\r
48 BOOTP, RARP, etc.) is not finished yet.\r
49 EFI_OUT_OF_RESOURCES - Could not add the entry to the routing table.\r
50 EFI_NOT_FOUND - This route is not in the routing table\r
51 (when RouteInfo->DeleteRoute is TRUE).\r
52 EFI_ACCESS_DENIED - The route is already defined in the routing table\r
53 (when RouteInfo->DeleteRoute is FALSE).\r
