+VF enable jumbo frame by configuring DPDK PF Tests 
+==================================================
+
+Description
+===========
+
+when do MTU set on VF port of ixgbe NIC, jumbo frame mode need enable 
+by host pf, to receive Jumbo Frames with a configurable maximum packet 
+length that is greater than the standard maximum Ethernet frame length (1518 bytes).
+
+Prerequisites
+=============
+
+1. Hardware:
+   Ethernet Controller 10G X550T 1563
+   Ethernet Connection X552/X557-AT 10GBASE-T 15ad
+   
+2.Bind PF ports to igb_uio driver::
+
+	usertools/dpdk-devbind.py --bind=igb_uio 0000:af:00.0
+  
+3.Create 1 VF device from PF devices,then bind the created VF to igb_uio driver::
+
+	echo 1 > /sys/bus/pci/devices/0000\:af\:00.0/max_vfs
+	usertools/dpdk-devbind.py --bind=igb_uio 0000:af:10.0
+
+4.Start testpmd on host::
+
+	./x86_64-native-linux-gcc/app/testpmd -c 0xf -n 4 -w af:00.0 --file-prefix=PF -- -i
+	testpmd> set verbose 1
+	testpmd> set promisc 0 off
+	testpmd> start
+ 
+5.Start VF testpmd::
+
+	./x86_64-native-linux-gcc/app/testpmd -c 0xf -n 4 -w af:10.0 --file-prefix=VF -- -i
+	testpmd> set verbose 1
+	testpmd> start
+  
+Test Case1: Mtu is greater than 1518
+====================================
+  
+Set MTU on vf port::
+
+	testpmd> stop
+	testpmd> port stop 0
+	testpmd> port config mtu 0 2000
+	testpmd> port start 0
+	testpmd> start
+
+Send the packet what the length is greater than 1518 less than 2000 to PF port::
+
+	sendp([Ether(dst='B4:96:91:57:78:FC')/IP()/("X" * 1600)], 
+iface="enp175s0f1", count=1)
+
+Send the packet what the length is greater than 1518 less than 2000 to VF port::
+
+	sendp([Ether(dst='CE:43:0B:2E:AE:64')/IP()/("X" * 1600)], 
+iface="enp175s0f1", count=1)
+  
+Check that packets length greater than the standard maximum frame 
+(1518) less than 2000 can received on VF port and PF port.
+ 
+Send the packet what the length is greater than 2000 to PF port::
+
+	sendp([Ether(dst='B4:96:91:57:78:FC')/IP()/("X" * 2100)], 
+iface="enp175s0f1", count=1)
+	
+Send the packet what the length is greater than 2000 to VF port::
+	
+	sendp([Ether(dst='CE:43:0B:2E:AE:64')/IP()/("X" * 2100)], 
+iface="enp175s0f1", count=1)
+
+Check that packets length greater than 2000 can not received on VF port and PF port.
+  
+Quit VF testpmd, and then restart the VF testpmd::
+
+	testpmd> quit
+	./x86_64-native-linux-gcc/app/testpmd -c 0xf -n 4 -w af:10.0 --file-prefix=VF -- -i
+	testpmd> set verbose 1
+	testpmd> start
+
+Send the packet what the length is greater than 1518 less than 2000 to VF port again::
+    
+	sendp([Ether(dst='CE:43:0B:2E:AE:64')/IP()/("X" * 1600)], 
+iface="enp175s0f1", count=1)
+  
+Check that packets length greater than the standard maximum frame 
+(1518) less than 2000 can received on VF port.
+  
+Send the pkts what the length is greater than 2000 to VF port again::
+
+	sendp([Ether(dst='CE:43:0B:2E:AE:64')/IP()/("X" * 2100)], 
+iface="enp175s0f1", count=1)
+	
+Check that packets length greater than 2000 can not received on VF port. 
+ 
+Test case2: The maximum mtu(9710)
+=================================
+
+Set MTU on vf port::
+
+	testpmd> stop
+	testpmd> port stop 0
+	testpmd> port config mtu 0 9710
+	testpmd> port start 0
+	testpmd> start
+  
+Send the packet what the length is 9710 to PF port::
+
+	sendp([Ether(dst='B4:96:91:57:78:FC')/IP()/("X" * 9676)], 
+iface="enp175s0f1", count=1)
+	
+Send the packet what the length is 9710 to VF port::
+	
+	sendp([Ether(dst='CE:43:0B:2E:AE:64')/IP()/("X" * 9676)], 
+iface="enp175s0f1", count=1)
+	
+Check that packets length is 9710 can received on VF port and PF port.
+
+Quit VF testpmd, and then restart the VF testpmd::
+
+	testpmd> quit
+	./x86_64-native-linux-gcc/app/testpmd -c 0xf -n 4 -w af:10.0 --file-prefix=VF -- -i
+	testpmd> set verbose 1
+	testpmd> start
+  
+Send the pkts what the length is 9710 to VF port::
+
+	sendp([Ether(dst='CE:43:0B:2E:AE:64')/IP()/("X" * 9676)], 
+iface="enp175s0f1", count=1)
+
+Check that packets length is 9710 can received on VF port.
