+/** \brief Configure TCP source addresses, for active-open TCP sessions
+
+ TCP src/dst ports are 16 bits, with the low-order 1024 ports
+ reserved. So, it's necessary to provide a considerable number of
+ source IP addresses if one wishes to initiate a large number of
+ connections.
+
+ Each of those addresses needs to have a receive adjacency -
+ either a /32 or a /128 - and vpp needs to answer (proxy) arps or
+ neighbor discovery requests for the addresses.
+
+ @param client_index - opaque cookie to identify the sender
+ @param context - sender context, to match reply w/ request
+ @param is_ipv6 - 1 for ipv6, 0 for ipv4
+ @param vrf_id - fib table / vrf id for local adjacencies
+ @param first_address - first address that TCP will use
+ @param last_address - last address that TCP will use
+*/
