The current implementation is designed to emit packets to an physical ether= net interface and tries to maximize the hardware throughput. There is already c= ode to limit the packet rate injected (maxpps) further. The whole code is able to inject any netgraph messages into any netgraph network, despite the dependency to a physical interface prohibits this at t= he moment. This patch allows to use the ng_source module to be used in arbitary netgra= ph network. In order to limit the rate of packets injected, the maxpps part ne= eds to be enforced if there is no assigned ethernet interface available. I personally use this patch to profile somewhat complex netgraph networks, which terminate in i.e. in eiface nodes. --=20 You are receiving this mail because: You are the assignee for the bug.=
