Broadcast segmentation fails when root != 0

[Mellich]

The ACCL XRT test suite fails for large counts on the bcast with root 1 tests.
ACCL was synthesized with TCP stack and UDP stack from dev at 36eebbb. All other tests passed.
The error appears in both versions.

Setup:

• 2x Alveo U280, directly connected
• XRT:2.12
• Platform: xilinx_u280_xdma_201920_3
• Vitis: 2021.2
• Tests using streams are commented out to prevent deadlocks

Execution:
TCP version: mpirun -n 2 bin/test -f -x the.xclbin -t -b 2 -s 512
UDP version: mpirun -n 2 bin/test -f -x the.xclbin -u -b 2 -s 512

Output for the two failing tests:

Interesting. I've seen this before when testing the segmentation in hardware, but I assumed this was because of a problem in the segmentation implementation.

[TristanLaan]

Actually looking further into it, I'm pretty sure this is caused by the segmentation implementation. In the current dev branch the maximum segment size is not set to the rxbufsize, which makes the segmenting fall back to the default 1 KiB. On the dev branch only bcast implements segmentation. This has been 'fixed' (the segmentation of broadcast is still broken) in #127, where the segment size is set correctly.
