and /.profile. The problem is that install(1) will unlink the old file
before it installs the new one, which means that in the best case we
have to compare the changes for the old file twice.
So, change the logic to first test to see if the link exists, then
install the file. Then if the link was there and we're using -i, just
create the link in /root and be done with it. Otherwise display the
message to the user and give them the option.
Because we are now sorting things before doing the comparison we can
know conclusively that the files in / should be the sources, and the
files in /root will be the targets, so adjust the paths accordingly.
While I'm here, split a too-long error message into two lines and
just return at the end of handling these files instead of setting
the variable that says "do nothing" and then returning at the end
of the function anyway.
Just like a similar change we made to the TTY code about half a year
ago, make these strings look similar.

VT3119 which seems to be VIA's internal model name and VT3119
wouldn't be available to end users.

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.

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.

system properly tracks threads and is safe to unload, remove the

threads are executing the eventhandler, sleep in this case to make it safe for

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
