Hello, I'm observing some kind of congestion with virtualbox-ose-kmod-5.2.12 on -current. Frames from the guest make it through ng_ether(4), but frames coming from ng_ether(4) seem to choke this direction. Initially, the guest successfully can get a DHCP lease (both, v4 and v6) and all DNS traffic is passed successfully, but as soon as the first TCP transmission with some payload happens (jumbo frames, but quick test showed that also 1514-frames choke the LAN->guest direction), not even ARP replys reach the guest anymore. At least they are traversing ng_ether(4). So there's either a general netgraph(4) problem or vboxnetflt(4) problem on -current. To rule out a known vboxnetflt(4) limitation/failure, I'd like to know if somebody successfully uses vboxnetflt(4) from virtualbox-ose-kmod-5.2.12 on stable/11|11.2. Thanks, -harry
