Patches #1,2,3 trade options specified as struct fields for options
specified as function parameters. Tbh, this seems to be an opinionated
stylistic change, what is the need for it?
If anything, I think that this is less readable:
> + client_rx_fd = __connect_to_fd_opts(srv_fd, 0, &rx_opts);
compared to this:
> struct network_helper_opts tx_ops = {

(given that by patch #3 three parameters are added to
__connect_to_fd_opts() *and* it also accepts options).
