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?
