Following the 'bufferbloat' recommendation: https://www.bufferbloat.net/projects/bloat/wiki/Tests_for_Bufferbloat/ i've added to a typical bridge (in a debian/ProxmoxVE server): iface enp2s0f1 inet manual ethernet-autoneg on link-speed 100 link-duplex full hardware-dma-ring-tx 18 offload-tso off offload-gso off offload-gro off auto vmbr1 iface vmbr1 inet static address 172.17.44.50 netmask 255.255.255.0 gateway 172.17.44.1 bridge_ports enp2s0f1 bridge_waitport 30 bridge_stp off bridge_fd 0 and seems to work, eg link speed is 100Mbit/s and offload parameters are off. But i've tried to do the same thing with an LACP bond, adding this parameters both to single interfaces and also on the bond interface, both seems get ignored. It is not possible to set hardware parameters in bond and/or in bond members?! Thanks. -- dott.
