The DPDK driver may directly provide the internal HW mbuf in the dequeued structure.
So don't try to free the mbufs from that dequeued structure, but the ones we allocated.
- modify retrieve_ldpc_enc_op() to store encoded results in a packed format
- add timing measurements for T2 encoder
- add simde implementation for bit reversal
- Introduce new bit reversal implementation using simde_mm_gf2p8affine_epi64_epi8
instruction, based on https://wunkolo.github.io/post/2020/11/gf2p8affineqb-bit-reversal/.
This implementation requires GFNI and AVX512VL support on the target machine.
Since this branch aims to bring all the encoded segments packed and contiguous,
it doesn't make anymore sense to have one output array per segment.
Therefore this commit moves the output array to the TB instead of the segment and adapts its size.
TODO: Adapt the size of f where it is relevant.
The offset provided for each code block in the HARQ combined input and output buffer shall not be above 512.
A modulus was performed on the offset of the TB in the buffer to avoid this situation.
But the offset of the code block was added afterward so that the total offset was sometimes going above 512.
This commit performs the modulus after adding the code block offset.
- Remove all variables (like OPENAIR1), they serve no purpose and make
unnecessarily long lines
- Remove linking to T, it does not seem to be necessary
- Avoid intermediate variables to keep sources, and declare libraries
directly, making for shorter code
