at91_emac AND macb?

macb works for AVR32AP700x and (at least) for AT91SAM9260/9G20/9XE.

What is the deal with at91_emac? Is it required for some AT91's because macb does not work there?

Does it provide better "results" than macb?

Hello,

I think the separation has historical reasons. For AT91RM and AT91SAM existed separate drivers and separate arch. I remeber in older datascheets the ethernet inteface also marked with MACB. In my opinion, the at91_emac the latest drivers (NET_MULTI api SoC access via c structurs).

But I dont know the exact differences are not of single use devices. Please ask Xu, Hong

Best regards
