From 3357642e65e9454c3da64b62c0ed987ee4010008 Mon Sep 17 00:00:00 2001 From: "Russell King (Oracle)" Date: Mon, 9 Mar 2026 09:39:28 +0000 Subject: net: stmmac: reorder structs to reduce memory consumption Reorder some of the stmmac structures to allow them to pack better, thereby using less memory. On aarch64, sizeof(struct stmmac_priv) was 880, and with this change becomes 816, saving 64 bytes, which is an 8% saving.
