* Major overhaul and cleanup of ng_source node.Gleb Smirnoff2005-04-051-162/+132
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Make some basic grammar and style fixes to ng_source.c and ng_source.h.Bosko Milekic2005-03-101-7/+5
| | | | | | | | The latter was particularly violated by someone's editor in the past, due to an effect I like to call "premature linewrapping." Notes: svn path=/head/; revision=143387

* Mechanically rename s/ng_timeout/ng_callout/g, s/ng_untimeout/ng_uncallout/g.Gleb Smirnoff2004-12-011-4/+4
| | | | | | | | | | This is done to keep both versions in RELENG_5 and support both APIs. Reviewed by: scottl Approved by: julian (mentor), implicitly Notes: svn path=/head/; revision=138268
* - Make ng_timeout() to use callout() interface instead of timeout().Gleb Smirnoff2004-11-021-8/+7
| | | | | | | | | | - Remove callout-hacking from ng_untimeout(). Approved by: julian (mentor) MFC after: 1 month Notes: svn path=/head/; revision=137138

* Slight cosmetic changes.Julian Elischer2004-07-201-1/+0
| | | | | | | | | | | | Also introduce a macro to be called by persistent nodes to signal their persistence during shutdown to hide this mechanism from the node author. Make node flags have a consistent style in naming. Document the change. Notes: svn path=/head/; revision=132464

* Make ng_source to work with non-ethernet interfaces. We do this byHartmut Brandt2004-01-261-2/+37
| | | | | | | | | | introducing a START_NOW command. This command does not send and GET_IFINDEX message downstream (to wait for the response from the ETHERNET node), but directly starts the sending process.

This is NOT YET CONVERTED TO -current. This node is a source for preprogrammed packets at a known rate for testing. I will convert it to -current "in place" but will MFC teh original pre-conversion variant as that is what is originally submitted. Man page my me, info from Dave's README.
