Most seem to be on 3.2 and 3.4, but I've heard people say Broadcom now has BSP for 4.1. However, since basically all high-speed devices use a hardware packet accelerator, even with newer kernels you might not get anti-bufferbloat benefit because these packet accelerators have their own buffer handling. I might be in the position to test one of these broadcom 4.1 based devices in the next few months, I'll run some tests and report back if that happens. -- Mikael Abrahamsson email: swmike@swm.pp.se
