Message-ID: <20200921175442.16789-3-skardach@marvell.com>

To: <kuba@...nel.org>, <davem@...emloft.net>, <sgoutham@...vell.com>,

Subject: [PATCH net-next v2 2/3] octeontx2-af: prepare for custom KPU profiles
Refactor KPU related NPC code to prepare for upcoming KPU customization
functionality. This requires the following:
* Gathering all KPU profile related data into a single adapter struct.
* Converting the built-in MKEX definition to a structured one to
streamline the MKEX loading.
* Convert LT default register configuration into a structure which may
later on be customized.
* Add a single point for KPU profile loading, currently using only
built-in profile.
