Re: [ethmac] New host interface (without DMA)

["satya" <satya@iwavesystems.net>]

Hi Igor,
thanks for your kind reply.You said that u r not using DMA descriptors
anywhere in the core.If so,in case of trnasmitting a frame,how the
descriptors will be loaded with source address and destination address which
are stored only in DMA descriptors.I want to know how you are accessing  the
DMA?
Pls do reply me immly.

Thanks and Regards
