To enable Tx side offload on tunneling packet, driver should set
correct tunneling parameters: (1) EIPT, External IP header type;
(2) EIPLEN, External IP; (3) L4TUNT; (4) L4TUNLEN. This parsing
behavior is based on (ol_flag & PKT_TX_TUNNEL_MASK). And when
it's a tunneling packet, MACLEN defines the outer L2 header.
Also, we define TSO on each kind of tunneling type as a capabilities.
Now only i40e declares to support them.

Exported header files used by applications should allow the strictest

This commit prevents the following errors:

Note: the standard does not require implementations to issue a diagnostic
message with these, and such errors do not occur with recent GCC or clang

of the application (because other callbacks of the application

This change is to make user code simpler. For PMDs which do not fill any
packet types, return 0 instead of -ENOTSUP as suggested by Bruce.
Usually, users only care if the required (by ptype_mask) ptypes can be
filled by the specified PMD. If the PMD implements dev_supported_ptypes_get
func is not important. And the introduce of another return value (-ENOTSUP)
would increase the complexity of user programs to check it.
Besides, there are ways to know if a PMD implements the func:
a. see doc/guides/nics/overview.rst.
b. use (~1) as parameter ptype_mask, then check if return 0.

Many sample apps include internal buffering for single-packet-at-a-time

better suited to being implemented in the ethdev API.
The new APIs in the ethdev library are:
* rte_eth_tx_buffer_init - initialize buffer
* rte_eth_tx_buffer - buffer up a single packet for future transmission
* rte_eth_tx_buffer_flush - flush any unsent buffered packets
* rte_eth_tx_buffer_set_err_callback - set up a callback to be called in
case transmitting a buffered burst fails. By default, we just free the
unsent packets.
As well as these, an additional reference callbacks are provided, which
frees the packets:
* rte_eth_tx_buffer_drop_callback - silently drop packets (default
behavior)
* rte_eth_tx_buffer_count_callback - drop and update user-provided counter

rte_ethdev.c for debugging purposes only. We can eliminate the second
copy of the functions by moving the additional debug checks into the
copies of the functions in the header file. [Any compilation for
debugging at optimization level 0 will not inline the function so the
