hello. Occasionally I see messages like the following from my FreeBSD-12.2/dom0 machine. Is this related to the issue of the NetBSD domu's seeing bursts of oversized packets, which I assume is caused by packets getting sent from the dom0 to the domu in batches rather than one at a time, each with an interrupt signal, or, the xen equivalent? On the domu's I see: xennet0: discarding oversize frame (len=1518) I see the following messages on the dom0, but not necessarily at the same time as the above messages appear in the domu's. Any ideas? -thanks -Brian Apr 25 14:56:35 xen-lothlorien kernel: xnb(xnb_ring2pkt:1532): Unknown extra info type 255.
