In some testcases, especially when iperf test duration is short (10s),
client does not report on time and report collection is interrupted.
This commit increase timeout for iperf/iperf3 commands.

xran's xran_bm_init() uses rte_pktmbuf_pool_create() to allocate DPDK
buffers. For a 1x1 configuration, the number of buffers might be too
small, and rte_pktmbuf_pool_create() might fail. This commit ensures
that we increase the number of buffers to have enough even in a 1x1
configuration. This works by chosing the next power of two, which is
recommended as per DPDK documentation.
Closes-Bug: #750
Neighbor configuration can be given by gNB.conf
get_MeasConfig function is extended as it will prepare A2 / A3 Report
Configs. Single Meas Obj is used for all.
rrc_gNB_process_MeasurementReport function is extended to process A2 /
A3 measurement events. helper functions are written to fetch neighbour
cell informations from sequence containers.
(get_neighbour_cell_information, get_neighbour_config)
- neighbour_config.conf file includes neighbour and measurement related parameters
Neighbour List:
- nr_cellid: the identity of existing cell who has neighbour
- neighbour_cell_configuration(list): includes the identity parameters
of the neighbour cell such:
- gNBID (incase of N2 Handover / to be identified from AMF)
- nr_cell_id (target gNB needs to consider)
- physical_cellId (needed for measurement reporting)
- absoluteFrequencySSB (needed for measurement reporting)
- subcarrierSpacing (needed for measurement reporting)
- plmn / tracking area code (incase of N2 Handover / needed for AMF
to identify / allow HO)
NR Measurement Configuration
- Periodical
- enable (default is 0, 1 enables the reporting)
- includeBeamMeasurements, maxNrOfRS_IndexesToReport (configurable
reporting parameters)
- A2
- enable (default is 0, 1 enables the reporting)
- threshold , timeToTrigger (configurable reporting parameters)
- A3
- cell_id (the nr_cellid of neighbour cell. So this A3 parameters
will be used for the neighbour
- [-1] means default. so it can be applied to any neighbour if
there is no specific config
- Neighbour specific A3 Threshold can be used or default can be
selected depending to the neighbour planning
- The neighbour-config.conf specifies, apply default A3 for
neighbours 3 and 4 | apply specific one for neighbour 2
- offset, hysteresis, timeToTrigger (configurable reporting parameters)
the neighbour_config.conf can be included in the gNB.conf file. Example
is given: gnb.sa.band78.106prb.rfsim.neighbour.conf
A sequence array container is used for neighbour cell configuration. RRC
structure has this container. A Measurement configuration structure is
defined. This structure has Periodical / A2 Event structures and also a
sequence container for A3 Event List.
These structures are filled during the initialization. While F1 Setup
Response is coming from DU to CU, the intra frequency / inter frequency
neighbour decision is given for the existing cell. Also new neighbours
could be added here if needed.
With the capabilities now given as part of this MR, it happens that when
checking the "docker compose config", the container_name might not be
close to the service name. Something like
service:
cap_drop:
...
cap_add:
...
container_name:
This is inconvenient, as the previous grep for the service name + 3
lines might not cover the service name. To circumvent this, give the
service name directly in "docker compose config". (no clue why it has
not been done like this from the start)
