From ab90563d4f50f619ced10754f4cecb87c49b1c74 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Sun, 10 Jan 2021 13:17:52 +0100 Subject: [PATCH] r8169: deprecate support for RTL_GIGA_MAC_VER_27 RTL8168dp is ancient anyway, and I haven't seen any trace of its early version 27 yet. This chip versions needs quite some special handling, therefore it would facilitate driver maintenance if support for it could be dropped. For now just disable detection of this chip version. If nobody complains we can remove support for it in the near future. v2: - extend unknown chip version error message Signed-off-by: Heiner Kallweit Link: https://lore.kernel.org/r/ca98f018-a0e1-8762-e95c-f0ad773a0271@gmail.com Signed-off-by: Jakub Kicinski --- drivers/net/ethernet/realtek/r8169_main.c | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/drivers/net/ethernet/realtek/r8169_main.c b/drivers/net/ethernet/realtek/r8169_main.c index f06e130512a83..ddcf4870f0256 100644 --- a/drivers/net/ethernet/realtek/r8169_main.c +++ b/drivers/net/ethernet/realtek/r8169_main.c @@ -1981,7 +1981,11 @@ static enum mac_version rtl8169_get_mac_version(u16 xid, bool gmii) { 0x7c8, 0x280, RTL_GIGA_MAC_VER_26 }, /* 8168DP family. */ - { 0x7cf, 0x288, RTL_GIGA_MAC_VER_27 }, + /* It seems this early RTL8168dp version never made it to + * the wild.
