OpenWrt depreciated pfifo_fast in favor of fq_codel in 2012, and have not looked back. It (and BQL) is ever present on all their Ethernet hardware and most of their wifi, no configuration required. It's just there.
That said many OpenWrt chips have offloads that bypass that, and while speedier and low power, tend to be over buffered.
