I've set up the Proxmox to use link aggregation, and it works OK with the basic settings (MTU standard 1500). If I want to use 9000 MTU, how should I set it up? Should I set the 9000 MTU to every NIC (eno1-eno4), or to the bond0 , or to the vmbr0, or should I set the MTU to every one of them, or to some weird combination of those?
