From ff0ea57fa30e860d3373acd1383e9d9599144b58 Mon Sep 17 00:00:00 2001 From: Lorenzo Bianconi Date: Mon, 18 Sep 2023 12:29:08 +0200 Subject: net: ethernet: mtk_wed: introduce mtk_wed_buf structure Introduce mtk_wed_buf structure to store both virtual and physical addresses allocated in mtk_wed_tx_buffer_alloc() routine. This is a preliminary patch to add WED support for MT7988 SoC since it relies on a different dma descriptor layout not storing page dma addresses.
