This adds the NIPC parameter, which configures support for processing
multiple items or samples per clock cycle. With this enabled, the FFT
block can process at rates higher than 250 MSPS, such as 500 MSPS and
beyond.

On the CPU to Ethernet path (c2e) in some configurations the trailing
bytes length was not being properly set in TUSER. This can lead to
extra bytes being added onto packets. Most of the time this is fine,
since the extra bytes would be ignored by the underlying protocols.
But when the packet was near the MTU size, it could lead to an
oversized packet that would get dropped by the network or host
computer.

This wrapper was using TUSER for the number of trailing bytes, but it
wasn't properly enabled, which could cause it to be ignored in some
cases.

This was set to 1 in UHD 4.7, but it must be 2 for all channels to
have sufficient bandwidth.

Fixed an issue where the DDC could experience an arithmetic overflow
when receiving a full-scale signal with non-zero DDS frequency.

This reverts commit e572bab3ee5aa40f57bdc6e11d6381cad1d1401a.
The problem with skipping the "unnecessary" bash wrappers is that Ubuntu
systems use 'dash' as a default shell, which does not support our build
infrastructure. While we do recommend not using dash for building FPGA
builds in our documentation, it's not obvious that dash is the problem
when calling rfnoc_image_builder.

Remove unused stall_probability arguments from

Together with an update to the LMK04832 register config according to
TIs data sheet, all clock outputs are now aligned to SYSREF rising edge.
Therefore, I needed to adjust the SYSREF capture mechanism inside the
RFSoC and the SYSREF LMK Delay.
SYSREF is now captured first at the falling edge of PRC.
To be on the safe side, we are still double synchronizing SYSREF
afterwards on the rising edges of PRC.
As we are now independent of any MCR regarding timing constraints the
SYSREF Delay is also set to '0' for all X4xx devices.

In cases when the info FIFO fills, it was possible for
in_pkt_info_tvalid to be asserted then on the next cycle
in_pkt_info_tready would deassert, in which case the input would be
dropped. This change ensures that tvalid remains asserted until tready
deasserts.

The TX radio will normally transmit a late not-timed packet when an
underflow occurs between packets within a burst. However, if it was
only one cycle late, then the packet would be dropped. This change
rearms the state machine more quickly in this corner case to allow
this late packet to be accepted. The underflow error will still be
reported.

This Python utility was getting a bit rotten. The following updates
where made:
- Reformatted using ni-python-styleguide
- Fixed formatting of regex strings by declaring them 'raw'
- Updated docstrings and any linter issues
On Pyton 3.12 and beyond, this will no longer throw SyntaxError
warnings.

Previously, the build tools for the FPGA bitfiles would try and
autodetect the Vivado executable, but would allow for a `vivado_lab`
executable. However, Vivado Lab Edition can't build bitfiles nor run
testbenches. Its only use with the USRP FPGA build tooling is to run
`viv_jtag_program` and `viv_jtag_list` (which are command-line proxies
for probing FPGAs attached to JTAG, and for programming bitfiles over
JTAG, e.g. to an X3x0).
When Vivado Lab and Vivado were present, it was possible that we ran
into issues where Vivado Labs would be preferred, and then builds or
testbenches would fail.
We therefore remove the ability to use Vivado Lab. Running the Vivado
Lab Edition with the GUI, and loading and probing bitfiles is of course
still possible, but tools like `rfnoc_image_builder` can no longer
accidentally try to use Vivado Lab instead of regular Vivado.

The tready signal that was used when EN_MAGNITUDE equals 0 was not
correct. This commit allows EN_MAGNITUDE to be disabled.

This replaces the legacy RFNoC FFT block with a new one of the same
name that includes a superset of the original features. New features
include cyclic prefix insertion or removal and FFT sizes up to 64k.

The underlying Xilinx CORDIC IP uses 2 bits for the whole part of its
(X,Y) inputs and its magnitude output. So, having 17 bits means we have
enough precision to represent the entire range of an sc16. The 16-bit
CORDIC is insufficient to cover this entire range.
