From 0d5044b4e7749099b12da5f2c8618f04bb4fa82f Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Mon, 6 May 2024 10:50:40 -0700 Subject: [PATCH] lib: Allow for the DIM library to be modular Allow the Dynamic Interrupt Moderation (DIM) library to be built as a module. This is particularly useful in an Android GKI (Google Kernel Image) configuration where everything is built as a module, including Ethernet controller drivers. Having to build DIMLIB into the kernel image with potentially no user is wasteful.
