This patch series introduces HALO support for the CN20K platform. On earlier platforms (CN9K/CN10K), the NPA mempool required separate aura and pool contexts even for a 1:1 aura-to-pool mapping. This led to unnecessary context usage for the most common use case.
With CN20K, HALOs allow replacing this 1:1 aura/pool model with a single combined context, reducing context consumption and simplifying mempool management. Patch 1 adds HALO creation support in the ROC common layer. Patch 2 integrates HALO usage into the CN20K mempool driver and adds a new "halo_ena" devarg to enable or disable this feature.
