Subject: question: ip forwarding and fq/mq qdisc
Date: Fri, 14 Dec 2018 15:02:10 +0300 [thread overview]
Message-ID: <20181214120210.kmeuwvajuiwlp2n7@bars> (raw)
Hi all,
I have been running 4.18-rc8 kernel with enabled IP forwarding between
wired and wireless interfaces, where both interfaces
were configured as fq qdisc.
However after moving to 4.20-rc1 kernel the same configuration does not
work anymore: pass-through packets are not forwarded in both directions.
Forwarding starts working again only if I change qdisc of _both_ interfaces
to anything but fq/mq. For instance any combination of pfifo/fq_codel/noqueue
works fine.
Does it look like a regression or it is a known change in behavior ?
Regards,
Sergey
