ethernet does not work as it keeps flipping #14
Description
I am using meta-riscv/yocto to build a core-image-base where I also ensuring that we set CONFIG_MICREL_PHY=y but this also does not help in bringing up address on the phy, I can see the interface
but it never gets IP, udhcpc keeps trying. I also disabled udhcpc running on boot to avoid any races. And launch it manually after logging in. But it results in same results

I am using starfive_vic7100_evb_sd_net_defconfig but same is seen with fedora defconfig as well and also with https://github.com/starfive-tech/freelight-u-sdk/blob/starfive/conf/sdk_210209_defconfig
