Subject: [net Patch] octeontx2-af: Fix issue with loading coalesced KPU profiles
Date: Tue, 26 Mar 2024 17:51:49 +0530

The current implementation for loading coalesced KPU profiles has
a limitation.  The "offset" field, which is used to locate profiles
within the profile is restricted to a u16.

This restricts the number of profiles that can be loaded. This patch
addresses this limitation by increasing the size of the "offset" field.

Fixes: 11c730bfbf5b ("octeontx2-af: support for coalescing KPU profiles")
