And so far as I can tell, fq_codelis ubiquitous across all of linux and linux containers and vms, and we've headed off major trouble at the wifi pass with the OSX and QCA (ath9k, ath10k) implementations. 10s of millions deployed - but where it's most needed, it's not, and ISPs mostly ship it not. So while I do take heart in the enormous deployment and figure we'll turn the corner in the next year or seven on these other devices, I was grumpily looking over: http://conferences.sigcomm.org/sigcomm/2014/doc/slides/137.pdf again today, and wishing we had some way of addressing the structural problems we have with academic and industry research in general.

So yeah. Maybe with the right parts being availa= ble, one could aim at $50 or less, without sales channel markup. (Raspberry= Pi ARM64 boards don't have GigE, and I think that might be because the Gig= E interfaces are a bit pricey. However, the ARM64 SoC's available are typic= ally Celeron-class multicore systems. I don't know why there aren't more AR= M64 systems on a chip with dual GigE, but I suspect searching for them woul= d turn up some). > > -Toke > > [0] https://www.gl-inet.com/products/gl-ar750s/ > > _______________________________________________ > Cerowrt-devel mailing list > Cerowrt-devel@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/cerowrt-devel --=20 Dave T=C3=A4ht CTO, TekLibre, LLC http://www.teklibre.com Tel: 1-831-205-9740
