From c946b3047205d7e107be16885bbb42ab9f10350a Mon Sep 17 00:00:00 2001 From: Francois Romieu Date: Thu, 4 Oct 2007 00:42:50 +0200 Subject: [PATCH] r8169: revert part of 6dccd16b7c2703e8bbf8bca62b5cf248332afbe2 The 8169/8110SC currently announces itself as: [...] eth0: RTL8169sc/8110sc at 0x........, ..:..:..:..:..:.., XID 18000000 IRQ .. ^^^^^^^^ It uses RTL_GIGA_MAC_VER_05 and this part of the changeset can cut its performance by a factor of 2~2.5 as reported by Timo. (the driver includes code just before the hunk to write the ChipCmd register when mac_version == RTL_GIGA_MAC_VER_0[1-4]) Signed-off-by: Francois Romieu Cc: Timo Jantunen Signed-off-by: Jeff Garzik --- drivers/net/r8169.c | 16 +++++++++++++--- 1 file changed, 13 insertions(+), 3 deletions(-) diff --git a/drivers/net/r8169.c b/drivers/net/r8169.c index c921ec32c2..c76dd29c8e 100644 --- a/drivers/net/r8169.c +++ b/drivers/net/r8169.c @@ -1918,7 +1918,11 @@ static void rtl_hw_start_8169(struct net_device *dev) rtl_set_rx_max_size(ioaddr); - rtl_set_rx_tx_config_registers(tp); + if ((tp->mac_version == RTL_GIGA_MAC_VER_01) || + (tp->mac_version == RTL_GIGA_MAC_VER_02) || + (tp->mac_version == RTL_GIGA_MAC_VER_03) || + (tp->mac_version == RTL_GIGA_MAC_VER_04)) + rtl_set_rx_tx_config_registers(tp); tp->cp_cmd |= rtl_rw_cpluscmd(ioaddr) | PCIMulRW; @@ -1941,6 +1945,14 @@ static void rtl_hw_start_8169(struct net_device *dev) rtl_set_rx_tx_desc_registers(tp, ioaddr); + if ((tp->mac_version != RTL_GIGA_MAC_VER_01) && + (tp->mac_version != RTL_GIGA_MAC_VER_02) && + (tp->mac_version != RTL_GIGA_MAC_VER_03) && + (tp->mac_version != RTL_GIGA_MAC_VER_04)) { + RTL_W8(ChipCmd, CmdTxEnb | CmdRxEnb); + rtl_set_rx_tx_config_registers(tp); + } + RTL_W8(Cfg9346, Cfg9346_Lock); /* Initially a 10 us delay.
