From 07d91ec99a8a37d9b9f6d8ec3f16b97622a74893 Mon Sep 17 00:00:00 2001 From: "Russell King (Oracle)" Date: Wed, 15 Oct 2025 17:10:56 +0100 Subject: [PATCH] net: stmmac: rearrange tc_init() To make future changes easier, rearrange the use of dma_cap->l3l4fnum vs priv->flow_entries_max. Always initialise priv->flow_entries_max from dma_cap->l3l4fnum, then use priv->flow_entries_max to determine whether we allocate priv->flow_entries and set it up. This change is safe because tc_init() is only called once from stmmac_dvr_probe().
