From 8531c80800c10e8ef7952022326c2f983e1314bf Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Sat, 23 Jul 2022 16:29:31 +0200 Subject: [PATCH 3/5] net: ethernet: stmicro: stmmac: move dma conf to dedicated struct Move dma buf conf to dedicated struct. This in preparation for code rework that will permit to allocate separate dma_conf without affecting the priv struct.
