The tx_checksum command concerns outer IP checksum, not VxLAN checksum.
Actually there is no checkum in VxLAN header, there is one checksum in
outer IP header, and one checksum in outer UDP header. This option only
controls the outer IP checksum.

Add a new command related to csum forward engine:
csum parse-tunnel (on|off) (tx_port_id)
If enabled, the tunnel packets received by the csum forward engine are
parsed and seen as "outer-headers/inner-headers/data".
If disabled, the parsing of the csum forward engine stops at the first
l4 layer. A tunnel packet is seens as "headers/data" (inner headers are
included in payload).
Note: the port argument is the tx_port. It's more coherent compared
to all other testpmd csum flags.

Replace the "tx_checksum" command by "csum". It has several
advantages:
- it's more coherent with the forward engine name
- it's shorter
- the next commit will introduce a command that is related to
the csum forward engine, but about rx side.

Since previous commit, the flag PKT_TX_UDP_TUNNEL_PKT is not used by any PMD,
remove it from mbuf API and from csumonly (testpmd). In csumonly, the
PKT_TX_OUTER_IP_CKSUM flag is already set for vxlan checksum, providing
enough information to the underlying driver.

The definition of the flag PKT_TX_UDP_TUNNEL_PKT in rte_mbuf.h was:
TX packet is an UDP tunneled packet. It must be specified when using
outer checksum offload (PKT_TX_OUTER_IP_CKSUM)
This flag was used to tell the NIC that the offload type is UDP
(I40E_TXD_CTX_UDP_TUNNELING flag). In the datasheet, it says it's
required to specify the tunnel type in the register. However, some tests
(see [1]) showed that it also works without this flag.
Moreover, it is not explained how the hardware use this
information. From a network perspective, this information is useless for
calculating the outer IP checksum as it does not depend on the payload.
Having this flag in the API would force the application to specify the
tunnel type for something that looks only useful for this PMD. It will
limit the number of possible tunnel types (we would need a flag for each
tunnel type) and therefore prevent to support outer IP checksum for
proprietary tunnels.
Finally, if a hardware advertises "I support outer IP checksum", it must
be supported for any payload types.
This has been validated by [2], knowing that the ipip test case was fixed
after this test report [3].

From i40e datasheet:
The IP header type and its offload. In case of tunneling, the IIPT
relates to the inner IP header. See also EIPT field for the outer
(External) IP header offload.
00 - non IP packet or packet type is not defined by software
01 - IPv6 packet
10 - IPv4 packet with no IP checksum offload
11 - IPv4 packet with IP checksum offload
Therefore it is not needed to fill the IIPT field if no offload is
requested (we can keep the value to 00). For instance, the linux driver
code does not set it when (skb->ip_summed != CHECKSUM_PARTIAL). We can
do the same in the dpdk driver.
The function i40e_txd_enable_checksum() that fills the offload registers
can only be called for packets requiring an offload.

Testpmd has the capability of changing the forwarding cores and ports in runtime.
If these are changed when forwarding, two issues may be encountered:
- If "show config fwd" is used, changes made in the core list are applied.
Therefore, trying to stop forwarding may hang testpmd,
since it could be waiting for cores to stop that are not actually running anything
- If the port list is changed, when stopping forwarding,
it may miss the stats of some of the ports that were actually being used.

The Link bonding library is incorrectly using receive packet type flags
in the transmit policy hashing functions, which would cause packets
generated locally to be incorrectly distributed across the slave
devices. This patch completely removes the dependency on the packet
type flags and uses the ether_type from either the Ethernet header or
the VLAN headers for branching.
This patch also includes the associate changes in the test suite and in

type flags.
