Jesse,
Dmesg hasn't changed for a while .. and sadly it is not time-stamped. Below is
the tail:

These stats are coming from your NIC? Assuming yes, it's unlikely that
they are caused by OVS directly because those are hardware counters.
Since OVS runs before hardware transmit, in order for the packet to be
dropped in hardware it would have to already have passed through OVS.
What are the outputs of dmesg and ovs-dpctl show?
