 3. Then run the same steps of PF xstats Checks, get same result.
 note: because one port forwarding packets, so check rx and tx both in port 0.

+Test Case: PF negative xstats check
+===================================
+1. Blind the PF to vfio-pci::
+
+    ./usertools/dpdk-devbind.py -b vfio-pci {pf_pci}
+
+2. Launch testpmd with default mtu::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c f -n 4 -- -i
+    testpmd> set fwd mac
+    testpmd> start
+    testpmd> clear port xstats all
+
+3. Set the mtu for the port where the data packet is sent::
+
+    ifconfig ens7 mtu 5018
+
+4. Send jumbo frames::
+
+    sendp(Ether(dst="00:00:00:00:01:00", src="52:00:00:00:00:00")/IP()/Raw(load="X"*4980), iface="ens7")
+
+5. Check port 0 xstats::
+
+    Check rx port can not receive packet.
+    Check ``rx_errors`` and ``rx_oversize_errors`` increased, but other statistics are 0 for tx port.
