e60cb443ab Merge remote-tracking branch 'origin/fapi-spatial-stream-mapping' into integration_2026_w22 (!3827)
Antenna port indexing of txdataF using FAPI spatial stream indices

This MR implements the FAPI's spatial stream indexing to pass antenna
port indices to L1 for MU-MIMO.

Closes #1022.

80088121d3 nfapi: fix UCI payload byte length for bit_len multiples of 8
bit_len / 8 + 1 overcounts by 1 when bit_len is an exact multiple of 8.
Replace with (bit_len + 7) / 8 across all pack/unpack sites for PUSCH
and PUCCH 2/3/4 SR/HARQ/CSI payloads, and in the utility functions
(eq, copy, size calculator, dump) and unit test fill functions.

Fixes UCI.indication unpack failure against cuBB when CSI-1 report
is 8 bits.

9ba2e7ca5b Revert "Removed TRP-scheme byte from UL BF PDU to Interop with Aerial 25-1 (FAPI 10.02)"
This commit broke compatibility with Aerial when compiled with -DSCF_FAPI_10_04_SRS=ON. It was decided that this should become the default.

This reverts commit 8beb382277.

1ea164468f Refactor fapi_nr_p5_message_unpack to have the same signature as nfapi_nr_p5_message_header_unpack.
This change is done in preparation to add the header unpack functions to the VNF and PNF structures as function pointers, used to peek the message headers prior to processing.
Add a faux fapi_nr_p7_message_header_unpack with the same signature as nfapi_nr_p7_message_header_unpack, to be used for the P7 header unpack function pointer.

Change the unpacking to pull only the needed bytes, and skip over the padding, when not Aerial
Change SRS.indication dumping function to also print the report TLV contents
Change SRS.indication unitary test to fill the last 4 byte block of the report TLV according to the length, with padding

bcbf7ab975 Move functions for packing/unpacking RACH.indication
Changed parameter in unpack function to be inline with other unpack functions.
Changed nfapi_p7_allocate call to calloc to avoid dependency to NFAPI_LIB.

Added unitary test for RACH.indication( test pack/unpack, free, copy and compare )
Added constant NFAPI_NR_RACH_IND_MAX_PDU to follow constants related to other P7 messages limiting the maximum number of PDUs to use.

Removed now unneeded dependency to NFAPI_LIB and NFAPI_USER_LIB
