Subject: Re: stmmac driver...

Hello Jie Deng


In your cover letter you wrote

dwc-eth-xxx.x
  The DWC ethernet core layer (DWC ECL). This layer contains codes
can be shared by different DWC series ethernet cores

Does this mean that code in dwc-eth-xxx.x is common to all
the different Synopsys IPs, GMAC, XGMAC and XLGMAC ?


Regards,
Niklas
