Wireshark is broken. It needs to know TP_STATUS_CSUMNOTREADY
means that the checksum is partial and will only be completed
when the hardware sends the packet out.
Alternatively disable checksum offload with ethtool.
Or take the packet traces "outboard" of the NIC somewhere/somehow.
What problem(s) led to your taking the packet trace in the first place?
