To possibly reduce the latency when polling packets by activating it from the network interface for N microseconds. The kernel by doing so, increase the CPU(s) activity bound to the socket significantly. Note that not only the kernel needs to have support enabled for it (which the average distribution usually does) but the network interface itself needs to support it too. If not, it is just a no-op.
