Openwrt下Ping 100%丢包，驱动相关问题

Question

有熟悉Atheros解决方案和OpenWrt系统的人吗？我的测试床在Atheros-SDK镜像下运行良好，而当在OpenWrt镜像上运行时，我的以太网接口(Eth0)出现了"ping 100%丢包“。我甚至继续使用寄存器的设置值，例如ETH_CONF、XMII_CONF，但它还不起作用。

任何建议都将是appreciated.Thanks!！我在arch/mips/ath79/mach-db120.c上的以太网设置是：

ath79_register_mdio(0, ~(BIT(5)));
ath79_eth0_data.phy_if_mode = PHY_INTERFACE_MODE_RGMII;
ath79_eth0_data.phy_mask = BIT(5);default is BIT(0)
ath79_eth0_data.mii_bus_dev = &ath79_mdio0_device.dev;
ath79_eth0_pll_data.pll_1000 = 0x06000000;
ath79_eth0_data.duplex = DUPLEX_FULL;
ath79_register_eth(0);

如果我将th79_eth0_pll_data.pll_1000修改为0x46000000

(设置1805002c GIGE_QUAD位)，然后它可以ping，但仍然有3%-5%甚至更多的ping loss.strange！我真的很想知道ag71xx相关代码有什么问题吗？分段引导日志为：

您需要指定您正在使用的OpenWRT版本才能得到一些答案！
