[dpdk-dev] [PATCH 0/6]Support VxLAN on fortville

[Jijiang Liu]

The patch set supports VxLAN on fortville,and based on current mbuf structure,
when the new mbuf structure done, there will be minor changes later.

It includes:
 - Support VxLAN packet filter by configuring UDP port, and add tunneling 
   UDP APIs.
 - Support VxLAN cloud filters: It is used to use MAC, VLAN to point
   to a queue. The filter types supported include below:
   1. Inner MAC and Inner VLAN ID
   2. Inner MAC address and inner VLAN ID, tenned ID.
   3. Inner MAC and tenant ID
   4. Inner MAC address
   5. Outer MAC address, tenant ID and inner MAC
 - Support VxLAN TX check offload, which include outer and inner L3(IP), 
   inner L4(UDP,TCP and SCTP) 

jijiangl (6):
  Add VxLAN packet identification
  Test vxlan packet identification in testpmd
  Add Cloud filter API
  Test cloud filter API in testpmd
  Add VxLAN TX checksum offload
  Test VxLAN Tx checksum offload

[dpdk-dev] [PATCH 2/6]app/test-pmd:test vxlan packet identification

[Jijiang Liu]

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

[dpdk-dev] [PATCH 3/6]i40e:Add VxLAN Cloud filter API

[Jijiang Liu]

Support VxLAN cloud filters,which is used to use MAC, VLAN to point
   to a queue. The filter types supported include below:
   1. Inner MAC and Inner VLAN ID
   2. Inner MAC address and inner VLAN ID, tenned ID.
   3. Inner MAC and tenant ID
   4. Inner MAC address
   5. Outer MAC address, tenant ID and inner MAC

[dpdk-dev] [PATCH 6/6]app/testpmd:test VxLAN Tx checksum offload

[Jijiang Liu]

Add test cases in testpmd to test VxLAN Tx Checksum offlad, which include IP4 and IPV6 case,
and also include inner L3 and L4 test cases.

I prefer to have a separated commit for API (ethdev) and another one for
implementation (i40e).

About API, why name it cloud filter instead of VxLAN?

Thanks

Ok, I can separate the commit into two patches.

VxLAN is just a kind tunnel type, there are another tunnel types based on protocol type, they are below.
Tunnel Type:
* 0x0: VXLAN
* 0x1: NVGRE or other MAC in GRE
* 0x2: Geneve
  0x3: IP in GRE
Currently, I just implemented VxLAN tunnel type, and we will support another tunnel types in cloud filter API later.

OK, I understand. But cloud filter is just a marketing name.
Please let's stick to technical and precise names.
It seems these tunnels are L2 over IP, right?

All are L2 over L3(UDP) -  General name  - Network Overlay.
