D2没份，openwrt通过重构MUX代码实现了2Gbps的CPU总带宽。

原文如下：

ramips: mt7621-dts: mux phy0/4 to gmac1
Mux the MT7530 switch's phy0/4 to the SoC's gmac1 on devices where RGMII2pins are available. This achieves 2 Gbps total bandwidth to the CPU usingthe second RGMII.The ports called "wan" are muxed where possible. On a minority of devices,this is not possible. Those cases:mt7621_ampedwireless_ally-r1900k.dts: lan3mt7621_ubnt_edgerouter-x.dts: eth0mt7621_gnubee_gb-pc1.dts: ethbluemt7621_linksys_re6500.dts: lan1mt7621_netgear_wac104.dts: lan4mt7621_tplink_eap235-wall-v1.dts: lan0mt7621_tplink_eap615-wall-v1.dts: lan0mt7621_ubnt_usw-flex.dts: lan1The "wan" port is just what the vendor designated on the board/plasticchasis of the device. On a technical level, there is no difference betweena lan and wan port on MT7621AT, MT7621DAT and MT7621ST SoCs. Preferconnecting to WAN via the port described above for these devices to benefitthe feature brought with this patch.mt7621_d-team_newifi-d2.dts cannot benefit this feature, although it lookslike it should, because the rgmii2 pins are wired to unused components.Tested on a range of devices documented on the GitHub PR.Link: [color=var(--color-accent-fg)]#10238Signed-off-by: Ar&#305;n&#231; üNAL <arinc.unal@arinc9.com>
