ago, make these strings look similar.

This tunable allows one to enable (1) or disable (0) gestures like tap
and tap-hold on Synaptics TouchPad when the Extended mode isn't enabled
(ie. "hw.psm.synaptics_support" not set).
By default, the value is -1 in order to keep the current behaviour of
not enabling/disabling gestures explicitly.

- Due to rounding error, setting watchdog to a really small
timeout (<1 sec) was turning the watchdog off. It should
set the watchdog to a small timeout instead.
- Implemented error checking in ipmi_wd_event(), as required
by watchdog(9).

similar to pflog(4).
To use the feature, just put the 'log' options on rules
you are interested in, e.g.
ipfw add 5000 count log ....
and run
tcpdump -ni ipfw0 ...
net.inet.ip.fw.verbose=0 enables logging to ipfw0,
net.inet.ip.fw.verbose=1 sends logging to syslog as before.
More features can be added, similar to pflog(), to store in
the MAC header metadata such as rule numbers and actions.
Manpage to come once features are settled.
perform a function such as ejecting a 3G autoinstaller disk. The eventhandler
system properly tracks threads and is safe to unload, remove the
setting/clearing of a function pointer in the kernel by u3g(4) which included a
tsleep for safety.
threads are executing the eventhandler, sleep in this case to make it safe for
module unload. If the runcount was up then an entry would have been marked
EHE_DEAD_PRIORITY so use this as a trigger to do the wakeup in
eventhandler_prune_list().

controllers. TX/RX interrupt mitigation is controlled by
VGE_TXSUPPTHR and VGE_RXSUPPTHR register. These registers suppress
generation of interrupts until the programmed frames counter equals
to the registers. VT61xx also supports interrupt hold off timer
register. If this interrupt hold off timer is active all interrupts
would be disabled until the timer reaches to 0. The timer value is
reloaded whenever VGE_ISR register written. The timer resolution is
about 20us.
Previously vge(4) used single shot timer to reduce Tx completion
interrupts. This required VGE_CRS1 register access in Tx
start/completion handler to rearm new timeout value and it did not
show satisfactory result(more than 50k interrupts under load). Rx
interrupts was not moderated at all such that vge(4) used to
generate too many interrupts which in turn made polling(4) better
approach under high network load.
This change activates all interrupt moderation mechanism and
initial values were tuned to generate interrupt less than 8k per
second. That number of interrupts wouldn't add additional packet
latencies compared to polling(4). These interrupt parameters could
be changed with sysctl.

With interrupt moderation there is no more need to loop in
interrupt handler. This loop always added one more register access.
While I'm here remove dead code which tried to implement subset of
interrupt moderation.

static if possible;
- add an ipfw_ prefix to all public functions to prevent conflicts
(the same should be done for variables);

- clarify some comments;
- remove some misspelling of names (#define V_foo VNET(bar)) that

At this time we pull out from ip_fw2.c the logging functions, and
support for dynamic rules, and move kernel-only stuff into
netinet/ipfw/ip_fw_private.h
No ABI change involved in this commit, unless I made some mistake.
ip_fw.h has changed, though not in the userland-visible part.
