RE: [avr-libc-dev] Ethernet & IP networking support?

[Weddington, Eric]

See Ethernut:
<http://www.ethernut.de/>

or the uIP project:
<http://www.sics.se/~adam/uip/index.php/Main_Page>f

The main thing to understand is that the 8-bit AVR devices do not have an 
on-chip Ethernet peripheral. So there is almost zero chance that Ethernet 
capabilities will be added to avr-libc. You will have to use external projects 
like those above.

Subject: [avr-libc-dev] Ethernet & IP networking support?
 

        Apparently, there's at least some interest in Ethernet and IP
        networking support for AVR (say, [1-3].)

        Now, there're various bits of the modern C libraries, both
        standard (say, htonl(1) [4], IN6_IS_ADDR_LOOPBACK () and struct
        in6_addr [5]) and not (say, struct ip6_hdr from netinet/ip6.h,
        GNU Libc [6]) that are plainly useful when implementing a
        networking stack on MCU-based devices and which should be quite
        easy to tailor for such a purpose.

        I wonder, is there a chance for such a "networking support" to
        appear in AVR Libc?  Or is there some other library for the
        things of that sort?
