0afe96c7bf cxgbe(4): Add a hw.cxgbe.starve_fl sysctl that can be used to starve the
freelists of netmap receive queues.  This is primarily to test various
congestion scenarios in the chip.

61f63f47b3 Since 'ticks' is an int, it may wrap around and cr_ticks at a certain
counter_rate will be greater than ticks, resulting in counter_ratecheck()
failure. To fix this take an absolute value of the difference between
ticks and cr_ticks.

31f494cdf5 cxgbe(4): Track the number of received frames separately from the number
of descriptors processed.  Add the ability to gather a certain maximum
number of frames in the driver's rx before waking up netmap rx.  If
there aren't enough frames then netmap rx will be woken up as usual.

a520a7cf2f Add a command that copies or migrates a data file from one DS to another.
This command can be used by a sysadmin to either copy or migrate a data
file on one DS to another DS.
Its main use is to recover data files onto a mirrored DS after the DS has
been repaired and brought back online.

ab80f5423d There's no need to walk through the tables looking for the smbios
table if we're just going to ignore it on arm, so expand, slightly,
the reach of the ifdef. Move the buffer to the inner block so we
don't have a separate #ifdef far away from these lines.

The issue on arm is that smbios_detect does unaligned accesses, which
in the u-boot implementing EFI context causes a crash.

c2bac3e1ba Provide a more direct interface to tell ZFS what the preferred handle
is. We tell the ZFS code now, and it checks rather than having a
callback to do the checks.

This will allow us to have a more graceful fallback code. In the
future, it's anticipated that we may fallback to a more global search
(or implement a command to do so) when reqeusted by the user, or we
detect a violation of the UEFI Boot Manager protocol severe enough to
warrant this backstop. For now, it just allows us to get rid of img as
a global.

c4273800ae lib32: Fix lib/libpmc/pmu-events files ending up in source directory.
This could happen with either WITHOUT_AUTO_OBJ=yes or MAKELEVEL>0 for
the initial 'make buildworld' command.

This now ensures that build-tools targets have 'make obj' ran if needed.

This is especially problematic for pmu-events since it is not directly
connected in the build.  Normally the 'make includes' call right before
this implicitly creates the objdir with a 'make obj' already but
misses pmu-events because it is disconnected from lib/libpmc.  Fixing that
would make this new 'make obj' pointless but it is being added to avoid
this problem in the future should another tool be connected like this.

e937d05124 extres/regulator: Switch boot_on/always_on sysctl to uint8
These are represented as booleans on the kernel-side, but were being exposed
as int. This was causing some funky things to happen when read later with
sysctl(8), e.g. randomly reading super-high when the value was actually

43b223f42e When retransmitting TCP SYN-ACK segments with the TCP timestamp option
enabled use an updated timestamp instead of reusing the one used in
the initial TCP SYN-ACK segment.

This patch ensures that an updated timestamp is used when sending the
SYN-ACK from the syncache code. It was already done if the
SYN-ACK was retransmitted from the generic code.

This makes the behaviour consistent and also conformant with
the TCP specification.

Each clock drivers if now fully subclassed, this have the advantage that
we can control the probe order.
Some clocks can have parents from other drivers, for example clocks in the
sun8i_r driver uses clocks from the main clock driver.
This worked before because the sun8i_r node is after the main ccu node in the
dtb and driver are probed in DTB order. This cannot work with the Display
Engine clocks as it is the first node in the DTB.
