Outputs a list of command line RTM functions.
4.3.4IP Route Table Entry
The IP lookup table entries reside in DRAM. The same table is used for both ATM and Ethernet destinations. The ATM and Ethernet Receive threads call the macro route_lookup() to obtain an index in the route table to the table entry. If the ITF field contains the ATM port type bit (0x80000000), then the entry is interpreted as an ATM destination, otherwise it is an Ethernet destination.
