The patch set supports VxLAN on Fortville based on latest mbuf structure. 
 
It includes:
 - Support VxLAN packet identification by configuring tunneling UDP port.
 - Support VxLAN packet filters. It uses MAC and VLAN to point
   to a queue. The filter types supported include below:
   1. Inner MAC and Inner VLAN ID
   2. Inner MAC address, inner VLAN ID and tenant ID.
   3. Inner MAC and tenant ID
   4. Inner MAC address
   5. Outer MAC address, tenant ID and inner MAC
 - Support VxLAN TX checksum offload, which include outer L3(IP), inner L3(IP) and inner L4(UDP,TCP and SCTP)
 
Change notes:
 
 v5) * Use the "packet_type" field to replace the "reserved2" field in the rte_mbuf structure.
     * Add the "inner_l2_l3_len" field in the rte_mbuf structure.
     * Add an offload flag PKT_TX_VXLAN_CKSUM in rte_mbuf.h
     * Change i40e_txd_enable_checksum() function for VxLAN Tx checksum offload setting.
     
jijiangl (8):
  Support VxLAN packet identification in librte_ether
  Support VxLAN packet identification in librte_pmd_i40e
  Test vxlan packet identification
  Add new filter framework
  Implement API of VxLAN packet filter in librte_pmd_i40e
  Test VxLAN packet filter API
  Support VxLAN Tx checksum offload
  Test VxLAN Tx checksum offload

Support tunneling UDP port configuration on i40e in librte_pmd_i40e.
Currently, only VxLAN is implemented, which include
 -  VxLAN UDP port initialization
 -  Implement the APIs to configure VxLAN UDP port in librte_pmd_i40e.

From: Jijiang Liu @ 2014-10-11  5:55 UTC (permalink / raw)
  To: dev

Add commands to test VxLAN packet identification, which include
 - use commands to add/delete VxLAN UDP port.
 - use rxonly mode to receive VxLAN packet.

From: Jijiang Liu @ 2014-10-11  5:55 UTC (permalink / raw)
  To: dev

Introduce a new filter framewok in librte_ether. As to the implemetation discussion, please refer to
http://dpdk.org/ml/archives/dev/2014-September/005179.html, and VxLAN tunnel filter implementation is based on
it.

Resend test-by email and fixed ugly format.

Patch name:		Support VxLAN on Fortville
Brief description:	Verify vxlan checksum detect/offload and tunnel filter work fine.
Test Flag:		Tested-by 
Tester name:		yong.liu@intel.com
Test environment:
			OS: Fedora20 3.15.8-200.fc20.x86_64
			GCC: gcc version 4.8.3 20140624
			CPU: Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz

Test Result Summary: 	Total 6 cases, 6 passed, 0 failed

Test Case - name:
			vxlan_ipv4_detect
Test Case - Description:
			Check testpmd can receive and detect vxlan packet 
Test Case -command / instruction:
			Start testpmd with vxlan enabled and rss disabled
			testpmd -c ffff -n 4 -- -i --tunnel-type=1 --disble-rss --rxq=4 --txq=4 --nb-cores=8 --nb-ports=2
						
			Set forward type to rxonly and enable detail log output
			testpmd>set fwd rxonly
			testpmd>set verbose 1
			testpmd>start

       			Send packets with udp/tcp/sctp inner L4 data
		
Test Case - expected test result:
			testpmd can receive the vxlan packet with different inner L4 data and detect whether the packet is  vxlan packet

Another comment is that packet_type is uint16_t, so you should change that uint8_t to uint16_t.

1) this option is not to "Compile tunneling UDP port support"
2) why is it a compile time option? should it be an API parameter or
a runtime option?

It's not very clear what packet type is.
There is maybe a more precise description, or is it hardware dependent?

It's not related to VXLAN.

I don't review the common API as it should be done in an unique place
and there are many copies in different patchsets. Let's focus on tunnels.

It's absolutely impossible to understand. Keep in mind the first goal of an
API: be used (which imply to be understood by users).
And I really don't understand why you define values for combination of
previous flags. Please, keep it simple.

This test report brings a lot of details. It's a good thing but we should
find a way to remove the "administrative words".
It should start with the tested-by line to allow copy paste in the commit log.

Why RSS is disabled?

--disble-rss: typo in command line. It raises doubts on the test.

I know that previous comment is "fields to support TX offloads",
but I'd prefer "for TX offloading of tunnels".
Maybe that "encapsulation" is better than "tunnel".
Just my opinion.

I would like to highlight that you are using 2 bytes in the second cache line
of the mbuf.
It deserves at least a line in the commit log.
Actually I'd prefer a separate patch for mbuf modifications.

Yes, it is related to VxLAN Tx Checksum test, I will put the changes to test VxLAN Tx checksum patch.

Change the comment as "tunneling UDP default port configuration"

In terms of VxLAN, "IANA has assigned the value 4789 for the VXLAN UDP port, and this value SHOULD be used by default as the
 destination UDP port.  Some early implementations of VXLAN have used other values for the destination port.  To enable
interoperability with these implementations, the destination port SHOULD be configurable."

I have provided a API to configure UDP port. But a default UDP port number is needed where PF startup if current mode is VxLAN mode.

As to why to add packet_type in mbuf structure, there are lots of explanations in 
Discussion of "[PATCH 03/13] mbuf: add packet_type field"
Anyway, I will add detailed description here.

The goal of defining values for combination of filter type in order to easily distinguish/check if the mandatory parameters are valid for a specific filter type,
for example, if the filter type is RTE_TUNNEL_FILTER_IMAC_IVLAN,  we just need to check if the inner MAC address and inner VLAN ID are valid.
To limit sanity checks to valid parameters the rte_tunnel_filter_type enumeration can be replaced/initialized by bit mask.

Furthermore, please look at i40e_tunnel_filter_param_check () function in "[PATCH v5 5/8]i40e:implement API of VxLAN packet filter in librte_pmd_i40e" patch.
static int
+i40e_tunnel_filter_param_check(struct i40e_pf *pf,
+			struct rte_eth_tunnel_filter_conf *filter) {
+    ...

+	if ((filter->filter_type & ETH_TUNNEL_FILTER_OMAC) &&
+		(is_zero_ether_addr(filter->outer_mac))) {
+		PMD_DRV_LOG(ERR, "Cannot add NULL outer MAC address\n");
+		return -EINVAL;
+	}
+
+	if ((filter->filter_type & ETH_TUNNEL_FILTER_IMAC) &&
+		(is_zero_ether_addr(filter->inner_mac))) {
+		PMD_DRV_LOG(ERR, "Cannot add NULL inner MAC address\n");
+		return -EINVAL;
+	}
+
+	return 0;
+}

Actually, If you really don't like rte_tunnel_filter_type definition style, and I can change it.

Please, do not consider a compile time option like "configurable".
There are some cases where the user cannot or don't want to rebuild DPDK.

OK, good.

Sorry, I don't understand this part.
Why are you adding a default tunnel when initializing?
Is it not enough to allow adding new tunnels with custom port?

Yes it must be moved in the patch related to checksum test.

Yes, you can just  replace this "enum rte_tunnel_filter_type" by an integer
like uint16_t. It won't change your tests.
