| pktgen is a high-performance testing tool included in the Linux kernel. Being |
| part of the kernel is currently best way to test the TX process of device driver |
| and NIC. pktgen can also be used to generate ordinary packets to test other |
| network devices. Especially of interest is the use of pktgen to test routers or |
| bridges which use the Linux network stack. Because pktgen is "in-kernel", it can |
| generate very high packet rates and with few systems saturate network devices as |
| routers or bridges. |
