[PATCH net-next v1 02/10] :crypto: octeontx2: add SGv2 support for CN10KB or CN10KA B0

Srujana Challa
2023-12-11T07:19:46Z

Scatter Gather input format for CPT has changed on CN10KB/CN10KA B0 HW
to make it comapatible with NIX Scatter Gather format to support SG mode
for inline IPsec. This patch modifies the code to make the driver works
for the same. This patch also enables CPT firmware load for these chips.
