Traces transmit packets.
Item | Description |
---|---|
ifp | Designates the address of the ifnet structure for this interface. |
mbuf | Designates the address of the mbuf structure to be traced. |
The net_xmit_trace kernel service traces the data pointed to by the mbuf parameter. This kernel service was added for those network interfaces that choose not to use the net_xmit kernel service to transmit packets. An application program (the iptrace command) reads the trace data and writes it to a file for the ipreport command to interpret.
The net_xmit_trace kernel service can be called from either the process or interrupt environment.
The net_xmit_trace kernel service has no return values.
