Hi Leonardo

Use RPS or RFS https://www.kernel.org/doc/html/latest/networking/scaling.html?highlight=rps

Okey, so in that case, how do you deal with it?

this is not related to accel, because accel-ppp is only control-plane for pppoe sessions so slow performance of pppoe is related to kernel, not to accel-ppp

Only difference is type of accel session. ipoe vs pppoe. So this is not related to accel?

This question is not related to accel, traffic forwarding is done by kernel, not by accel-ppp so please contact netdev (https://lore.kernel.org/netdev/ ) if you want to discuss it

Hi @Dimka88, I have implemented this feature for personal needs, but I would like to contribute with the code if possible. Please let me know how can I upload the changes so you can review. Should I do this on Github?

Summarize:
Issue appears with veth and vlan_mon only on 4.19. If use bridge instead, all will work properly. As Deb10 support expired around 1 year we make decision to delete tests on Deb10 from github test

I can confirm that kernel 5.10.0-0.deb10.24-amd64 is fixing issue on Debian 10.

It is not fixed in actual version. It is required to fix here: https://github.com/accel-ppp/accel-ppp/blob/2b865db72bc2ddc6411950d72f1c23e8ef115b8a/accel-pppd/ppp/ipcp_opt_ipaddr.c#L100 , https://github.com/accel-ppp/accel-ppp/blob/2b865db72bc2ddc6411950d72f1c23e8ef115b8a/accel-pppd/ppp/ipv6cp_opt_intfid.c#L209 , https://github.com/accel-ppp/accel-ppp/blob/2b865db72bc2ddc6411950d72f1c23e8ef115b8a/accel-pppd/ctrl/ipoe/ipoe.c#L668
