Hi,
this patch enables power management (suspend, resume) support for
zd1201. It fixes problems after wakeup for me, but these problems did
not appear everytime without this patch. it's a bit empirical, based on
what the usbnet does, so maybe not correct... Maybe someone can give it
a look before it's applied.
Thanks.
