For ixgbe, there is restriction that data buffers of any transmitted
packet must include at least 12 bytes of the src/dst Ethernet MAC
addresses as well as 2 bytes of the Type/Len field, otherwise, tx hang
would happen.
This patch adds check for those illegal packets and protects TX from
hanging.

Only TX->RX loopback is supported currently on 82599EB. If a user wants
to apply an another loopback configuration (!= IXGBE_LPBK_82599_TX_RX),
ixgbe PMD ignores it and continues the configuration without raising
any error.
Let's increase robustness of this part by checking if the requested
loopback mode is correct for the current device, before starting it.
If it is not valid, PMD will refuse to start.

The new functions for Rx and Tx offloads should not be inside the

when vector driver is disabled. For example:
ixgbe_ethdev.c:3636:36: error:

The only reason why bulk alloc disabled for the rings with
more than (IXGBE_MAX_RING_DESC - RTE_PMD_IXGBE_RX_MAX_BURST)
descriptors is the possible out-of-bound access to the dma
memory. But it's the artificial limit and can be easily
avoided by allocating of RTE_PMD_IXGBE_RX_MAX_BURST more
descriptors in memory. This will not interfere the HW and,
as soon as all rings' memory zeroized, Rx functions will
work correctly.
This change allows to use vectorized Rx functions with
4096 descriptors in Rx ring which is important to achieve
zero packet drop rate in high-load installations.

The behavior of PKT_RX_VLAN_PKT was not very well defined, resulting in
PMDs not advertising the same flags in similar conditions.
Following discussion in [1], introduce 2 new flags PKT_RX_VLAN_STRIPPED
and PKT_RX_QINQ_STRIPPED that are better defined:
PKT_RX_VLAN_STRIPPED: a vlan has been stripped by the hardware and its
tci is saved in mbuf->vlan_tci. This can only happen if vlan stripping
is enabled in the RX configuration of the PMD.
For now, the old flag PKT_RX_VLAN_PKT is kept but marked as deprecated.
It should be removed from applications and PMDs in a future revision.
This patch also updates the drivers. For PKT_RX_VLAN_PKT:
- e1000, enic, i40e, mlx5, nfp, vmxnet3: done, PKT_RX_VLAN_PKT already
had the same meaning than PKT_RX_VLAN_STRIPPED, minor update is
required.
- fm10k: done, PKT_RX_VLAN_PKT already had the same meaning than
PKT_RX_VLAN_STRIPPED, and vlan stripping is always enabled on fm10k.
- ixgbe: modification done (vector and normal), the old flag was set
when a vlan was recognized, even if vlan stripping was disabled.
- the other drivers do not support vlan stripping.
For PKT_RX_QINQ_PKT, it was only supported on i40e, and the behavior was
already correct, so we can reuse the same bit value for
PKT_RX_QINQ_STRIPPED.

VxLAN & NVGRE are supported by x550. As we know HW can parse
the packet and tell SW the type info. For VxLAN & NVGRE packets
there's some change. HW will not tell SW the info of the outer
header but the inner header instead. But we always take the
info as it's for the outer header. So the packet type info is
not right when x550 receives VxLAN & NVGRE packets.
As x550 only supports IPv4 VxLAN & NVGRE packets, we can tell
the outer header of VxLAN is IPv4 + UDP, and the outer header
of NVGRE is IPv4 only. What we don't know is if there's
optional field in the outer IPv4 header.
This patch implement the support of packet type for VxLAN &
NVGRE. And it fixes the wrong packet type issue either.
BTW:
It doesn't fix any existing commit as although it resolve an
issue it's more like a new feature but not a fix.

On receive side, the burst size now floor aligns to RTE_IXGBE_DESCS_PER_LOOP
power of 2. According to this rule, the burst size less than 4 still won't
receive anything.
(Before this change, the burst size less than 32 can't receive anything.)
_recv_*_pkts_vec returns no more than 32(RTE_IXGBE_RXQ_REARM_THRESH) packets.
On transmit side, the max burst size no longer bind with a constant, however
it still requires to check the cross tx_rs_thresh violation.
There's no obvious performance drop found on both recv_pkts_vec
and recv_scattered_pkts_vec on burst size 32.

The vector/SSE pmd used a different element type for the tx queue sw_ring
entries. This led to lots of typecasts in the code which required specific
use of bracketing, leading to subtle errors.
For example, in the original code:
txe = (struct ixgbe_tx_entry_v *)&txq->sw_ring[i];
instead needs to be written as:
txe = &((struct ixgbe_tx_entry_v *)txq->sw_ring)[i];
We can eliminate this problem, by having two software ring pointers in the
structure for the two different element types.

The calculations of what mbufs were valid in the RX and TX queues were
incorrect when freeing the mbufs for the vector PMD. This led to crashes
due to invalid reference counts when mbuf debugging was turned on, and
possibly other more subtle problems (such as mbufs being freed when in use)
in other cases.
To fix this, the following changes were made:
* correct counts and post-loop values in the TX release function for the
vector code.
* create a new separate RX release function for the RX vector code, since the
tracking of what mbufs are valid or not is different for that code path
