Subject: [PATCH net-next,v2,0/3] octeontx2-af: update CPT block for CN10KB and CN10KA B0

This commit addresses two key updates for the CN10KB and CN10KA B0:

1. The number of FLT interrupt vectors has been reduced to 2 on CN10KB.
The code is updated to reflect this change across the CN10K series.
2. The maximum CPT credits that RX can use are now configurable through
a hardware CSR on CN10KA B0. This patch sets the default value to optimize
peak performance, aligning it with other chip versions.

v2:
- Addressed the review comments.

Srujana Challa (3):
  octeontx2-af: use dynamic interrupt vectors for CN10K
  octeontx2-af: avoid RXC register access for CN10KB
  octeontx2-af: configure default CPT credits for CN10KA B0
