From: Auke Kok Date: Sat, 15 Apr 2006 02:04:46 +0000 (-0700) Subject: e1000: Esb2 wol link cycle bug and uninitialized registers X-Git-Tag: v2.6.18-rc1~1115^2~102^2~8 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4cc15f54991caf1572e03ffc65d9986e433007e2;p=linux-2.6 e1000: Esb2 wol link cycle bug and uninitialized registers Esb2 link didn't return after wol disable. The code previously assumed that writing reset to PHY_CTRL phy register turned the phy back on. In the ESB2 phy case that didn't occur. Add ESB2 to acquire/release_hw functions upon review it was discovered that esb2 was skipped on these functions Signed-off-by: Jesse Brandeburg Signed-off-by: Auke Kok Signed-off-by: John Ronciak --- diff --git a/drivers/net/e1000/e1000_main.c b/drivers/net/e1000/e1000_main.c index ac1e838741..8de9f9affa 100644 --- a/drivers/net/e1000/e1000_main.c +++ b/drivers/net/e1000/e1000_main.c @@ -359,6 +359,7 @@ e1000_release_hw_control(struct e1000_adapter *adapter) switch (adapter->hw.mac_type) { case e1000_82571: case e1000_82572: + case e1000_80003es2lan: ctrl_ext = E1000_READ_REG(&adapter->hw, CTRL_EXT); E1000_WRITE_REG(&adapter->hw, CTRL_EXT, ctrl_ext & ~E1000_CTRL_EXT_DRV_LOAD); @@ -392,6 +393,7 @@ e1000_get_hw_control(struct e1000_adapter *adapter) switch (adapter->hw.mac_type) { case e1000_82571: case e1000_82572: + case e1000_80003es2lan: ctrl_ext = E1000_READ_REG(&adapter->hw, CTRL_EXT); E1000_WRITE_REG(&adapter->hw, CTRL_EXT, ctrl_ext | E1000_CTRL_EXT_DRV_LOAD); @@ -419,7 +421,7 @@ e1000_up(struct e1000_adapter *adapter) uint16_t mii_reg; e1000_read_phy_reg(&adapter->hw, PHY_CTRL, &mii_reg); if (mii_reg & MII_CR_POWER_DOWN) - e1000_phy_reset(&adapter->hw); + e1000_phy_hw_reset(&adapter->hw); } e1000_set_multi(netdev);
