From b5025fd5205538b9585aa2b896d3b5e011cd6ffe Mon Sep 17 00:00:00 2001 From: Lorenzo Bianconi Date: Fri, 20 May 2022 20:11:32 +0200 Subject: [PATCH] net: ethernet: mtk_eth_soc: add rxd_size to mtk_soc_data Similar to tx counterpart, introduce rxd_size in mtk_soc_data data structure. This is a preliminary patch to add mt7986 ethernet support. Tested-by: Sam Shih Signed-off-by: Lorenzo Bianconi Signed-off-by: David S.
