16 /** \brief Configure TCP source addresses, for active-open TCP sessions
17 
18  TCP src/dst ports are 16 bits, with the low-order 1024 ports
19  reserved. So, it's necessary to provide a considerable number of
20  source IP addresses if one wishes to initiate a large number of
21  connections.
22 
23  Each of those addresses needs to have a receive adjacency -
24  either a /32 or a /128 - and vpp needs to answer (proxy) arps or
25  neighbor discovery requests for the addresses.
26 
27  @param client_index - opaque cookie to identify the sender
28  @param context - sender context, to match reply w/ request
29  @param is_ipv6 - 1 for ipv6, 0 for ipv4
30  @param vrf_id - fib table / vrf id for local adjacencies
31  @param first_address - first address that TCP will use
32  @param last_address - last address that TCP will use
