Functional changes: - Cut struct source_hookinfo. Just use hook_p pointer. - Remove "start_now" command. "start" command now requires number of packets to send as argument. "start" command actually starts sending. Move the code that actually starts sending from ng_source_rcvmsg() to ng_source_start(). - Remove check for NG_SOURCE_ACTIVE in ng_source_stop(). We can be called with flag cleared (see begin of ng_source_intr()). - If NG_SEND_DATA_ONLY() use log(LOG_DEBUG) instead of printf(). Otherwise we will *flood* console. - Add ng_connect_t method, which sends NGM_ETHER_GET_IFNAME command to "output" hook. Cut ng_source_request_output_ifp(). Refactor ng_source_store_output_ifp() to use ifunit() and don't muck through interface list. - Add "setiface" command, which gives ability to configure interface in case when ng_source_connect() failed. This happens, when we are not connected directly to ng_ether(4) node. - Remove KASSERTs, which can never fire. - Don't check for M_PKTHDR in rcvdata method. netgraph(4) does this for us. Style: - Assign sc_p = NG_NODE_PRIVATE(node) in declaration, to be consistent with style of other nodes. - Sort variables. - u_intXX -> uintXX. - Dots at ends of comments. Sponsored by: Rambler
