H313 EPHY ETH0 down 外置PHY rtl8201f ETH1会异常，
-
问题描述：
(1)将H313 GMAC0改为1000M网口，使用phy芯片为RTL8211FI-CG
代码改动如下：--- a/device/config/chips/h313/configs/p1/board.dts +++ b/device/config/chips/h313/configs/p1/board.dts @@ -86,7 +86,7 @@ }; gmac0: eth@05020000 { - phy-mode = "rmii"; + phy-mode = "rgmii"; status = "okay"; }; @@ -398,6 +398,24 @@ allwinner,drive = <0>; allwinner,pull = <1>; }; + gmac_pins_a: gmac@0 { + allwinner,pins = "PI0", "PI1", "PI2", "PI3", + "PI4", "PI5", "PI6", "PI7", + "PI8", "PI9", "PI10", "PI11", + "PI12", "PI13", "PI14", "PI15"; + allwinner,function = "gmac0"; + allwinner,muxsel = <2>; + allwinner,drive = <3>; + allwinner,pull = <0>; + }; + phy_rst: phy_rst@0 { + allwinner,pins = "PI16"; + allwinner,function = "gpio_out"; + allwinner,muxsel = <1>; + allwinner,data = <1>; + allwinner,drive = <0>; + allwinner,pull = <1>; + }; }; @@ -447,7 +465,7 @@ twi4: twi@0x05003000{ clock-frequency = <200000>; - pinctrl-0 = <&twi4_pins_a &lcd_bl_en &lcd_pwr_en &lcd_reset &lcd_pwm>; + pinctrl-0 = <&twi4_pins_a &lcd_bl_en &lcd_pwr_en &lcd_reset &lcd_pwm &phy_rst>; pinctrl-1 = <&twi4_pins_b>; status = "okay";（2）发生现象：
将eth0 down后，eth1原本100M全双工会自动变为10M半双工，如果不把eth1重新down并且up,不会恢复
即eth0 down后会影响eth1工作状态（3）以上1000m改动删除，那么是两个100M口，烧录在另外项目板子上，不会出现这个问题
即eth0 rmii模式不会出现这个问题。各位大佬有什么思路吗？

eth1 是H313 的 ephy 吗？ -
在软件中没有做好千兆网和百兆网的同时适配，只单独支持了千兆网
- 使能board.dts 的gmac0和gmac1的配置，即同时配置千兆网和百兆网
