从网心官方固件提取的内核5.10.xx的dts文件，对比了下大佬的，发现网卡clock部分有差异，大佬可以参考下 onething_kernel_5.10.dts.txt image

可以看到唯一的不同就是reset-deassert-us。但根据官方的解释，这里确实应该用长延时。

Subject: [PATCH] ARM: dts: meson: fix PHY deassert timing requirements

According to the datasheet (Rev. 1.9) the RTL8211F requires at least
72ms "for internal circuits settling time" before accessing the PHY
registers. On similar boards with the same PHY this fixes an issue where
Ethernet link would not come up when using ip link set down/up.

Fixes: a2c6e82e5341 ("ARM: dts: meson: switch to the generic Ethernet PHY reset bindings")
