There's a push at the moment to get the Qualcomm QSDK hardware offloading ported to modern kernels for IPQ8064 (Dual Core Arm SoC with an additional 2 Packet Processing cores) - sadly, Qualcomm haven't kept pace with upstream Kernel dev so it's a mammoth task.
And that's the crux of the problem with these SoC's - they can have fantastic packet processing performance (and in the case of the IPQ8064 NSS cores accelerated PPPoE, qdisc and crypto) but it's all tied up in vendor only repos, doesn't track upstream and so you're stuck with buggy vendor firmware.
