Technically, this is the wrong format, but it reduces the diffs in
-stable. Someday, when we get rid of ipfw1, I will put the port number
in the proper format both in kernel and userland.

The 550 version is location at address 1 but since it works right we
let the code find whatever PHY it can.
Fix a fragment issue on TX. If the number of frags are more then the
driver has allocated then bring all the frags together into one packet
and send it out. Code derived from the fxp driver.

request structure.
- Re-optimize the case of utrace being disabled by doing an explicit
KTRPOINT check instead of relying on the one in ktr_getrequest() so that
we don't waste time on a malloc in the non-tracing case.
- Change utrace() to return an error if the copyin() fails. Before it
would just ignore the request but still return success. This last is
a change in behavior and can be backed out if necessary.
transfer to a malloc'd buffer and use that bufer for the ktrace event.
This means that genio ktrace events no longer need to be synchronous.
- Now that ktr_buffer isn't overloaded to sometimes point to a cached uio
pointer for genio requests and always points to a malloc'd buffer if not
NULL, free the buffer in ktr_freerequest() instead of in
ktr_writerequest(). This closes a memory leak for ktrace events that
used a malloc'd buffer that had their vnode ripped out from under them
while they were on the todo list.

- Rename kern.ktrace_request_pool tunable/sysctl to
kern.ktrace.request_pool.
- Add a variable to control the max amount of data to log for genio events.
This variable is tunable via the tunable/sysctl kern.ktrace.genio_size
and defaults to one page.
and __stop_set_* became friendlier. This trick to force the export
of the section delimiter symbols is no longer necessary. We needed to
force this so that we could look up the symbols via a symbol table search
when the module was loaded at run time. ld used to eliminate them if
they were not referenced at compile/link time.
mode, and be more accurate about identifying begin lines so that spurious
ones don't have to be manually edited out, and be more forgiving about
errors so that -c mode is more useful.
