/** \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
