We concluded that the embedded router world was running 5-7 years behind linux mainline, sometimes as much as 10, and that the embedded linux world had been decimated by the great recession causing the collapse of companies like montavista. I recently took apart verizon FIOS's current firmware for one of their more popular routers. It's still running 2.6.21, which shipped in june, 2007. Overgeneralizing from this one data point, I am wondering if the trendline for new routing products tracking current software has got worse or better? I have generally assumed that "new wifi features" was a fundamental driver for semi-newer kernel versions in new products, and not much else. Edgerouters are still 3.10. I know of more than a few pre-bufferbloat-era things going back even further than that, but most hackerboards I've played with also don't go back very far. Odroid C2 was still 3.10 last I looked. There are still a few companies alive in this space (openrg being one that I know nothing about), but... --=20 Dave T=C3=A4ht CEO, TekLibre, LLC http://www.teklibre.com Tel: 1-669-226-2619
