我自制了一块imx8mp-ddr4-evk主板，两个网口完全按照官方开发板做的，软件使用的是real-time-edge-2.5，phy芯片也跟官方一样：rtl8211f，现在的问题是两个网口百兆网都是通的，千兆网会出现丢包现象，网卡的设备树配置信息如下：
&eqos {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_eqos>;
phy-mode = "rgmii-id";
phy-handle = <ðphy0>;
snps,force_thresh_dma_mode;
snps,mtl-tx-config = <&mtl_tx_setup>;
snps,mtl-rx-config = <&mtl_rx_setup>;
status = "okay";
mdio {
compatible = "snps,dwmac-mdio";
#address-cells = <1>;
#size-cells = <0>;
ethphy0: ethernet-phy@1 {
compatible = "ethernet-phy-ieee802.3-c22";
reg = <1>;
eee-broken-1000t;
realtek,clkout-disable;
};
};
mtl_tx_setup: tx-queues-config {
snps,tx-queues-to-use = <5>;
snps,tx-sched-sp;
queue0 {
snps,dcb-algorithm;
snps,priority = <0x1>;
};

snps,dcb-algorithm;
snps,priority = <0x2>;
};
queue2 {
snps,dcb-algorithm;
snps,priority = <0x4>;
};

snps,priority = <0x8>;
};

snps,priority = <0xf0>;
};
};
mtl_rx_setup: rx-queues-config {

snps,rx-sched-sp;

};

};

};

};
queue4 {

};
};
};
