Is there anyone who's familiar with Atheros solution ?
My router runs well on Atheros-SDK image while it was found that my ethernet interface(eth0) arose "ping 100% packet loss" when running on OpenWrt image. I even continue to use the registers' setting value,e.g.,ETH_CONF,XMII_CONF,but it doesn't work yet.

Any suggestions will be appreciated.Thanks!!

ethernet setting at arch/mips/ath79/mach-db120.c is:
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);

If I modified the th79_eth0_pll_data.pll_1000 to 0x46000000

(set the 1805002c GIGE_QUAD bit),then it can ping but still has 3%-5% or even more ping loss.strange! I realy want to know is there any issue with ag71xx relevant code ?
sectional bootlog is:
