Draft: Stability improvements for O-RAN FH 7.2

• library:
  • ignore if packets don't have payload instead of asserting => the gNB will show zero counters
  • do not hard code FFT size and numerology (important for FR2)
• implement #732
• update documentation:
  • describe counters
  • update NUMA spelling
  • reorganize configuration section (DPDK before gNB config because DPDK devices referenced in gnB config)
  • explain layer mapping
• patch: update to not ignore user's $(PKG_CONFIG_PATH), disable telemetry -> bumps version, need to recompile xran lib to force same version among users
• gNB
  • don't assert if PUCCH mismatches in frame/slot or activity to improve stability
  • print diagnostics if SIB1 too big for TBS

@jfiedler we should test this also rebuilding the xran lib as per the instructions (the expected outcome being that everything works as before)

I am fine with it.

@schmidtr I would like to test it before you merge.

we will test it in the integration branch, but as you like. can you do it until 4pm today?

(and it has been tested already by someone external at NEU)

Okay in that case I am fine, just mention the ptp version in the document.

Todo

• explain layer mapping
• put DPDK config before RU/gNB config because the gNB config references DPDK devices created in the DPDK config step
• add commit Raymond to improve handling of FFT size and FR2 config
• add #732
• fix for PUCCH assert

mentioned in issue #732

mentioned in merge request !2564 (merged)

added 5G-NR label and removed documentation label
