Hello! I am having a very strange issue that I'm not quite sure how to solve. On my PVE host (clean install) I can access the internet and ping things on my local network as well, as is expected. I can also ping guests but it seems to be very lossy, losing the first 3-5 packets and then randomly losing them after that. Within 2 debian containers and 1 bazzite (fedora based distro) vm, I can sometimes (intermittently) ping things on my lan but I can't ping the gateway, anything on the internet (unless I leave it running 20+ minutes, then sometimes) or the proxmox host except for sometimes when I can ping the host for a few seconds. I can also ping the guest from devices on my lan with an occasional packet getting through. The longer I leave the vm/ct running the easier time it seems to have connecting to things but it is never fully consistent. DHCP doesn't seem to work on guests at all. I have tried using `ethtool -K eno1 tx off rx off tso off gso off gro off` from here which seemed to maybe help at first but after rebooting the host the issue came back, and I dont seem to be able to get it to work again. This is all being done on a supermicro x11ssl board which has an Intel i210 AT network controller with an i3-6100 cpu.
