By default, packets sent through packet sockets pass through the kernel's
qdisc (traffic control) layer, which is fine for the vast majority of use
cases.
For traffic generator appliances using packet socket that intend to flood
the network with brute force i.e., to test devices under load in a similar
fashion to pktgen, this layer can be bypassed by setting this integer option
to 1. Side-effects are that packet buffering in qdisc layer is avoided
which will lead to increased drops when net device transmit queues are busy;
