yes.

Been working on libreqos.io lately, which is targetted at small ISPs,
and uses our latest XDP and cake code. It's getting marvelous - the
ipv6 code landed today, and we think we're good for 20gbit on 16 cores
on < $2k hw with purely free software.

Preseem (also using fq_codel) has been delivering a nice shaping
middlebox into the wisp market for going on 6 years.
