For multi-seg mbuf, ip->total_length should be pkt_len subtract
ether len.

l4_len is not fixed, althrough mostly it is a fixed value,
but when guest using iperf to do some tests, the l4_len
will have another 12 bytes optional fields.

When sending packets from virtual machine which in need of TSO
by hardware NIC, the inner L4 checksum is not correct on the
other side of the cable.
It's because get_psd_sum() depends on PKT_TX_TCP_SEG to calculate
pseudo-header checksum, but currently this bit is set after the
function get_psd_sum() is called. The fix is straightforward.
Move the bit setting before get_psd_sum() is called.

Based on previous fix of offload on VXLAN using i40e, applications
need to set proper tunneling type on ol_flags so that i40e driver
can pass it to NIC.

The extended unified packet type is now part of the standard ABI.
As mbuf struct is changed, the mbuf library version is incremented.

To unify packet types among all PMDs, bit masks of packet type for
'ol_flags' are replaced by unified packet type.
To avoid breaking ABI compatibility, all the changes would be
enabled by RTE_NEXT_ABI.

Add the tso-segsz option for TSO offload.
If the 'tso-segsz' is not 0, it means TSO offload is enabled.

Add Tx checksum offload configuration for inner header.
For UDP tunneling packet, the inner Tx checksum offload means
inner IPv4 and inner L4(TCP/UDP/SCTP).
