Does anybody have a free, in-kernel tool to generate packets quicky and send them out a particular etherent interface on FreeBSD? Something similar to pktgen on linux? I'm trying to excersize just the send-side of programmable firmware based NIC. The recieve side of the NIC firmware is not yet written, but I want to get started tuning and shaking the bugs out of the send side while the firmware author does the recieve path. The packets just get dropped on the floor by the NIC, so its a good way to test the interface.. I can add an arp entry and ping -l HUGEVAL, but that only generates 205K pkts/sec (where *think* I see 1.1 million pkts/sec with pktgen on linux, but I'm not sure I trust it). Thanks, Drew
