If the NIC has offloading enabled, I guess the stack knows this and
sends it bigger frames, knowing it will packetize them smaller? Because
I went into the adapter properties and turned off all the offloading
features, and now it is being reported as expected in WireShark. So I
guess when the NIC's offload capabilities are disabled, the stack
detects this and only sends it frames that are appropriate for the MTU?
