ebc457d1fa Make ng_pptpgre(8) netgraph node be able to restore order for packets
reordered in transit instead of dropping them altogether.
It uses sequence numbers of PPtPGRE packets.

A set of new sysctl(8) added to control this ability or disable it:

net.graph.pptpgre.reorder_max (1) defines maximum length of node's
private reorder queue used to keep data waiting for late packets.
Zero value disables reordering. Default value 1 allows the node to restore
the order for two packets swapped in transit. Greater values allow the node
to deliver packets being late after more packets in sequence
at cost of increased kernel memory usage.

net.graph.pptpgre.reorder_timeout (1) defines time value in miliseconds
used to wait for late packets. It may be useful to increase this
if reordering spot is distant.

4f1c28c8e1 Redo r339563: Remove joy(4) driver.
This driver was marked as gone in 12. We're at 13 now. Remove it.
Data from nycbug's dmesg cache shows only one potential user,
suggesting it never was used much. However, even though this device
has been obsolete for 15 years at least, sys/joystick.h is included in
a number of graphics packages still, so that remains. A full exprun
is needed before that can be removed.

83bf1fdc83 Revert r339563.
I held the mistaken belief this was completely unused. While the
driver is unused and likely not relevant for a long time,
sys/joystick.h lives on in maybe half a dozen ports, even though
hardware to use it hasn't been widely used in maybe 15 years.

0dd92926d8 Make it possible to disable NUMA support with a tunable.
This provides a chicken switch for anyone negatively impacted by
enabling NUMA in the amd64 GENERIC kernel configuration.  With
NUMA disabled at boot-time, information about the NUMA topology
is not exposed to the rest of the kernel, and all of physical
memory is viewed as coming from a single domain.

This method still has some performance overhead relative to disabling
NUMA support at compile time.

eb5896f52d cxgbe(4): Link related changes.
- Switch to using 32b port/link capabilities in the driver.  The 32b
  format is used internally by firmwares > 1.16.45.0 and the driver will
  now interact with the firmware in its native format, whether it's 16b
  or 32b.  Note that the 16b format doesn't have room for 50G, 200G, or
  400G speeds.

- Add a bit in the pause_settings knobs to allow negotiated PAUSE
  settings to override manual settings.

- Ensure that manual link settings persist across an administrative
  down/up as well as transceiver unplug/replug.

- Remove unused is_*G_port() functions.

20a8fc967a Address concerns about CPU usage while doing TCP reassembly.
Currently, the per-queue limit is a function of the receive buffer
size and the MSS.  In certain cases (such as connections with large
receive buffers), the per-queue segment limit can be quite large.
Because we process segments as a linked list, large queues may not
perform acceptably.

The better long-term solution is to make the queue more efficient.
But, in the short-term, we can provide a way for a system
administrator to set the maximum queue size.

We set the default queue limit to 100.  This is an effort to balance
performance with a sane resource limit.  Depending on their
environment, goals, etc., an administrator may choose to modify this
limit in either direction.
