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.

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.
