Hi Mohit,

I wonder what you think of the fq-pie developed for FreeBSD back in 2015 and merged in May 2016? (commit here <https://reviews.freebsd.org/rS300779>.)  It has been too long since I last looked, so would love your thoughts on how it aligns (or doesn't) with https://datatracker.ietf.org/doc/draft-tahiliani-tsvwg-fq-pie/?

cheers,
gja
