In order to move python2 out of the test framework to avoid py2 vs. py3
confusions upgrade the remaining test cases using scapy to work with py3.
That means only one version of scapy needs to be installed in the CI system.
It also gives a path forward for testing i386 issues observed in the CI
system with some of these tests.
Fixes are:
- Use default python from environment (which is 3.x these days).
- properly ident some lines as common for the rest of the file to avoid
errors.
- cast the calculated offset to an int as the division result is considered
a float which is not accepted input.
- when comparing payload to a magic number make sure we always add the
payload properly to the packet and do not try to compare string in
the result but convert the data payload back into an integer.
- fix print formating.

This patch modifies the zfs_ioc_snapshot_list_next() ioctl to enable it
to take input parameters that alter the way looping through the list of
snapshots is performed. The idea here is to restrict functions that
throw away some of the snapshots returned by the ioctl to a range of
snapshots that these functions actually use. This improves efficiency
and execution speed for some rollback and send operations.

Drop portions that are unlit or redundant with llvm-libunwind: builtin.c,
unwind.h, and unwind_arm_ehabi_stub.c.
This code should now work with -fPIE binaries, should we choose to build any
that way.
When backtrace() array is full, signal an error so the underlying
Itanium-style C++ exception handling library (llvm-libunwind) knows to stop
tracing instead of continuing. (It should stop on its own when it finishes
unwinding, so this is mostly an extra seatbelt against an infinite loop bug
in the unwinder.)
The fill_elf_hwcap() function expects to find only cpu nodes under the
/cpus entry of the device tree. Newer versions of QEMU insert a cpu-map
node which describes the CPU topology, breaking this function. To fix
this, simply skip any non-cpu entries.

[ARM] VFPv2 only supports 16 D registers.
r361845 changed the way we handle "D16" vs. "D32" targets; there used
to be a negative "d16" which removed instructions from the
instruction set, and now there's a "d32" feature which adds
instructions to the instruction set. This is good, but there was an
oversight in the implementation: the behavior of VFPv2 was changed.
In particular, the "vfp2" feature was changed to imply "d32". This is
wrong: VFPv2 only supports 16 D registers.
In practice, this means if you specify -mfpu=vfpv2, the compiler will
generate illegal instructions.
This patch gets rid of "vfp2d16" and "vfp2d16sp", and fixes "vfp2"
and "vfp2sp" so they don't imply "d32".

This ensures that the .text padding inserted by the amd64 linker script

This saves 320 bytes of the precious stack space.
The only negative aspect of the change I can think of is that the
struct thread increased by 320 bytes obviously, and that 320 bytes are
not swapped out anymore. I believe the freed stack space is much more
important than that. Also, current struct thread size is 1392 bytes
on amd64, so UMA will allocate two thread structures per (4KB) slab,
which leaves a space for pcb without increasing zone memory use.

The RK805 regs array was being allocated before it's required size was
known, causing the driver to use memory it didn't own. That memory
was subsequently allocated and used elsewhere causing later fatal data
aborts in rk805_map().
Whilst I'm here, add a sanity check to catch unsupported PMICs (this
shouldn't ever get hit because the probe should have failed).

In theory the eventhandler invoke should be in the same VNET as
the the current interface. We however cannot guarantee that for
all cases in the future.
So before checking if the fragmentation handling for this VNET
is active, switch the VNET to the VNET of the interface to always
get the one we want.

This is a driver for the USB3 PHY present in the RK3399.
While the phy support DP (Display Port) the driver doesn't has we have
no driver to test this with for now.
All the lane and pll configuration is just magic values from rockchip.
While the manual have some info on those registers it's really hard to
understand how to calculate those values (if there is a way).

The change to conform to RFC 8200 for overlapping fragments now frees
the entire reassembly queue if the overlapping fragments are not an
exact match.
As a result we do see one less packet in the timeout statistics from
expiry. No other statistics change as the event is not counted.
It can be argued that we should improve the statistics counters in
that case.
This test case update should have been committed alongside the original
commit.

When allocating the IPv6 fragement packet queue entry we do checks
against counters and if we pass we increment one of the counters
to claim the spot. Right after that we have two cases (malloc and MAC)
which can both fail in which case we free the entry but never released
our claim on the counter. In theory this can lead to not accepting new
fragments after a long time, especially if it would be MAC "refusing"
them.
Rather than immediately subtracting the value in the error case, only
increment it after these two cases so we can no longer leak it.

Previously the code used sbttous() before microseconds comparison in one
place, sbttons() and nanoseconds in another, division by SBT_1US and
microseconds in yet another.
Now the code consistently uses multiplication by SBT_1US to convert
microseconds to sbintime_t before comparing them with periods between
calls to sbinuptime(). This is fast, this is precise enough (below
0.03%) and the periods defined by the protocol cannot overflow.

Some controllers cannot preset future output value while the pin is in
input mode. This adds a fallback for those controllers. The new code
assumes that a controller reports an error in that case.
For example, all hardware supported by nctgpio behaves in that way.
This is a temporary measure. In the future we will use
GPIO_PIN_PRESET_LOW / GPIO_PIN_PRESET_HIGH to preset the output either
in hardware, if supported, or in software (e.g., in
gpiobus_pin_setflags).
While here, I extracted common functionality of gpioiic_set{sda,scl} and
gpioiic_get{sda,scl} to gpioiic_setpin and gpioiic_getpin respectively.

When we receive the packet with the first fragmented part (fragoff=0)
we remember the length of the unfragmentable part and the next header
(and should probably also remember ECN) as meta-data on the reassembly
queue.
Someone replying this packet so far could change these 2 (3) values.
While changing the next header seems more severe, for a full size
fragmented UDP packet, for example, adding an extension header to the
unfragmentable part would go unnoticed (as the framented part would be
considered an exact duplicate) but make reassembly fail.
So do not allow updating the meta-data after we have seen the first
fragmented part anymore.
The frag6_20 test case is added which failed before triggering an
ICMPv6 "param prob" due to the check for each queued fragment for
a max-size violation if a fragoff=0 packet was received.
