Subject: [net Patch] octeontx2-af: Fix issue with loading coalesced KPU profiles
Date: Tue, 26 Mar 2024 17:51:49 +0530 [thread overview]
Message-ID: <20240326122149.4377-1-hkelam@marvell.com> (raw)
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")
