The "or onward" part is talking about what the front-end does, rather than
what the workers do.  The front end *either* sends all packets to a host
for which each individual worker applies a (disjoint) BPF filter to the
stream to pick out those flows specifically for it; *or* the front end can
send the traffic to a switch that explicitly load-balances the traffic
across multiple 1G interfaces.
