Hi Arnd,
Thanks for your suggestions. it must be set the same strings in dsaf node and every enet node before.
it seems inappropriate. as Rob Herring <robh@xxxxxxxxxx> 's suggestions, that would solve associating
enet with a particular dsaf. so we discus the solution with Yisen Zhuang <yisen.zhuang@xxxxxxxxxx>.
we decide to use the new way instead of the old one.
Best regards,
yankejian
