The problem is that when using those RBs with MCS 28 we may exceed the
code rate 0.93 and according to 36.213 7.1.7 the UE may skip decoding
PDSCH entirely in this case.

This is a hack. The real solution is to check that the code rate is below
0.93 for each scheduling decision and, I don't know, reduce the MCS if the
code rate is above, so that in the end it is below. That means that we need
a proper resource grid for the configuration of the eNB and this is not an
easy thing (at least from my point of view) given all the possible
configurations for the eNB, so I prefer not to do it rather than do something
incorrect, thus this hack.

The problem of this hack is that we won't use all the available RBs for
scheduling, potentially reducing the maximum throughput achievable.

To be fixed properly at some time, by someone who understands fully the
resource grid and all the possible combinations (fdd/tdd, number of
antennas, whatever else).

[CI] for gNB Phy test : update of the execution timings ref values, according to the latest developments

MR !1197 : dongzhanyi-zte-develop1
function nr_generate_dci_top and nr_generate_dci has the frame_parms parameter, whose type is the structure NR_DL_FRAME_PARMS.
The better way is to pass the parameter as a pointer. 

MR !1176 : NR_phytest_bugfixes
This fixes a bug for configurations with less than 50 PRBs in phy-test mode.

MR !1142 : nr-dl-mimo-2layer

-fixes UL iperf log collection/analysis for UE module
-fixes iperf processes mgt for UE module

But that part should be moved to the MAC anyways

I have to revert this to be consistent with the OAI gNB.
But I think it is wrong to take the BWPSize from scc or scc_SIB, and the BWPStart from DLbwp[0].

MR !1188 : NR_gNB_initial_MIB_fix  
This MR fixes a bug for which the gNB would send an empty MIB in the first frames of execution. This is because MIB is generated every 8 frames but the first MIB wouldn't be generated before frame 8 at the beginning of each run.

MR !1184 : x2_handle_sctp_shutdown
Avoid eNB exiting after gNB tries to reconnect over X2 for NSA

bug found and fix proposed by: Francesco Mani

Merge branch 'develop' of gitlab.eurecom.fr:oai/openairinterface5g into x2_handle_sctp_shutdown

Initial implementation of NR5G Standalone Access Registration procedures with CN5G.
