Reimplement nFAPI message exchange between L1 and L2 following the
changes in parent commit removing msgDataTx.
Avoid direct calls and use NR_IF_module fptrs to avoid linking problems.
allowing to remove some function definitions that are not needed.
1. Refactor PDCCH PHY functions to take rxdataF of one OFDM symbol and
produce LLR for each search space. The modified functions take
rxdataF in a different format than that produced by nr_slot_fep(). So
for now a memcpy is used to change the array structure. Once
nr_slot_fep() is modified, this memcpy will no longer be needed and
will be removed.
2. Modify DCI functions to decode DCI in the last PDCCH symbol and
inidcate to MAC once.
3. Fix PDCCH monitoring for start symbol > 0.
4. Fix multiple PDCCH monitoring within slot.

Fix an issue in which the unpacking is erroneously deemed unsuccessful even though it succeed in pulling all the bytes, this was due to not properly handling the return value of pull16 which is either 0 or 2, not 0 or 1.
Check the results of push and pull operation with correct boolean operator.
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.
Modify documentation, and use a dedicated image name to make it clear in
the CI that it has SRS.

This reverts commit 8beb382277.
Refactor ULSCH scheduler towards more TDD pattern flexibility
Refactors ULSCH scheduler, notably to support "UL-heavy" TDD patterns,
e.g., DSUUU. Also allows to run TDD pattern2 with UL slots, which was a
limitation in the previous code.
Adds the capability to pack/unpack the TDD table in CONFIG.request
following both SCF222.10.02 (Tag 0x1027) and SCF222.10.04 (Tag 0x1035)
formats In the case of Aerial, the TDD table is packed following the
10.04 format, but with the 10.02 tag Prevent the packing of Digital
Beamforming table and Precoding Matrix table for Aerial
Add WLS as a transport option for VNF/PNF, refactor existing options
This MR adds a new transport mechanism for the VNF and PNF split, using
the Intel WLS library, which makes use of DPDK and shared memory to
transport messages. This transport mechanism is what is used to
interface with Radisys ODU, while also working with OAI VNF/PNF.
The VNF and PNF have been refactored so that the transport-specific
functions are isolated from the rest of the logic, and as such,
interchangeable by means of function pointers.
The same change is done for the packing/unpacking procedures, allowing
to switch between FAPI and nFAPI encoding.
This MR also reduces the amount of duplicated code, by refactoring the
VNF with Aerial, which now only has the transport-relevant functions, as
well as the ones that are unique to it ( for example, the unpacking
procedures where a secondary data buffer is used for the message
payloads )
Additionally a new callback is added to the VNF to process
ERROR.indication messages, which currently only indicates which message
originated the error, and which error occurred.
Checks whether there are at least 4 bytes available to pull tag and length values.
On tlv_list unpack, if the size is sent as 0, immediately exit the function
Created a function nr_error_ind_cb for the VNF that takes a received ERROR.indication and shows some details regarding the reported error from the PNF, since up until now it was not handled and treated as an unknown message.
Proper error handling procedure not created, only shows that the error occurred.
Add check to vnf_nr_handle_param_response for when phy_info is not found
The WLS VNF is in charge of Enqueueing the used blocks after usage for transport, this is done by keeping track of all blocks used, and calling WLS_Enqueue for all of them upon receiving a SLOT.indication
The common library exposes functions for the PNF to return the received blocks to the VNF for it to call WLS_Enqueue on them.
This is done in order to ensure the Blocks are returned after processing, also preventing the Dequeueing of blocks that are still being used, i.e. the internal value is not -1
All saved blocks are to be enqueued at the reception of a SLOT.indication by the VNF
Additionally, the definition of NFAPI_MAX_PACKED_MESSAGE_SIZE was moved to nfapi_interface.h and removed from the other headers, this is done to allow to set the maximum message size when using WLS by only changing the value in one place
Fixup fapi_nr_message_header_unpack call in nfapi_hex_parser
Switches the used socket type in pnf_interface.c and vnf_interface.c.
These values must always be the same in both components so the same socket type is used in both
Adds 3 new function pointers to the P5 and P7 VNF structures, allowing to configure which function to use to pack/unpack the messages, as well as unpack the message header, being then used seamlessly regardless of using the FAPI or nFAPI functions.

Changes the header unpack and message unpack functions to return true on success and false on failure, instead of an int
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.
Before, we only considered ta_Common_r17 and the SAT position from SIB19 to compute the initial timing advance value.
This is good enough if the satellite does not move too fast (e.g. GEO satellite).
Now we also consider ta_CommonDrift_r17 and the SAT velocity together with the epoch time from SIB19.
This improves the accuracy of the initial TA computation, esp. for LEO satellite scenarios.
Adds the packing and unpacking functions needed for the PM Table in CONFIG.request
This table tag is specified in SCF222.10.06(0x104B), previous versions didn't have a tag for this table, and this version of the spec introduces the parameter `num_pm_idx`, previously not present.
A struct nfapi_nr_pm_tlv_ve_t is added to represent this TLV in order to be able to use the pack_nr_tlv function.
The necessary additions to the utility functions are done to account for this table.
The unitary test is changed to fill this table with randomized data to test transport and copy.
Adds the packing and unpacking functions needed for the DBT Table in CONFIG.request
This table tag is specified in SCF222.5.0 (0x1043) and this tag is used to transport the table, previous versions did not include a tag for the table.
A struct nfapi_nr_dbt_tlv_ve_t is added to represent this TLV in order to be able to use the pack_nr_tlv function.
The necessary additions to the utility functions are done to account for this table.
The unitary test is changed to fill this table with randomized data to test transport and copy.
Add the ability to pack/unpack 2 new TLVs for analog beamforming
total_num_beams_vendor_ext and analog_beam_list
Add the unpack related changes for the first 2 vendor extension TLVs introduced related to beamforming.
For the moment the packing is guarded by an Assert to ensure it is not used.
Add the necessary utility function changes to support these VE TLVs
Add the necessary changes to the corresponding unitary test for pack/unpack,
commented for the moment, since the packing is disabled with an Assert.
