Subject: [PATCH net-next 3/4] selftests: forwarding: lib: Add start_traffic_pktsize() helpers

From: Petr Machata <petrm@...dia.com>

Add two helpers, start_traffic_pktsize() and start_tcp_traffic_pktsize(),
that allow explicit overriding of packet size. Change start_traffic() and
start_tcp_traffic() to dispatch through these helpers with the default
packet size.
