Replace the "reserved2" field with the "packet_type" field and add the "inner_l2_l3_len" field in the rte_mbuf structure.
The "packet_type" field is used to indicate ordinary packet format and also tunneling packet format such as IP in IP, IP in GRE, MAC in GRE and MAC in UDP.
The "inner_l2_len" and the "inner_l3_len" fields are added in the second cache line, they use 2 bytes for TX offloading of tunnels.

There are "some" destination UDP port numbers that have unque meaning.
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."
Add two APIs in librte_ether for supporting UDP tunneling port configuration on i40e.
Currently, only VxLAN is implemented in this patch set.

Add two commands to test VxLAN packet identification.
The test steps are as follows:
1> use commands to add/delete VxLAN UDP port.
2> use rxonly mode to receive VxLAN packet.

The filter types supported are listed below for VxLAN:
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 address.

From: Jijiang Liu @ 2014-10-23 13:19 UTC (permalink / raw)
To: dev
Add test cases in testpmd to test VxLAN Tx Checksum offload, which include
- IPv4 and IPv6 packet
- outer L3, inner L3 and L4 checksum offload for Tx side.
