Make a small improvement to slow path TX performance by adding in a
prefetch for the second mbuf cache line.
Also move assignment of l2/l3 length values only when needed.
What I've done with the prefetches is two-fold:
1) changed it from prefetching the mbuf (first cache line) to prefetching
the mbuf pool pointer (second cache line) so that when we go to access
the pool pointer to free transmitted mbufs we don't get a cache miss. When
clearing the ring and freeing mbufs, the pool pointer is the only mbuf
field used, so we don't need that first cache line.
2) changed the code to prefetch earlier - in effect to prefetch one mbuf
ahead. The original code prefetched the mbuf to be freed as soon as it
started processing the mbuf to replace it. Instead now, every time we
calculate what the next mbuf position is going to be we prefetch the mbuf
in that position (i.e. the mbuf pool pointer we are going to free the mbuf
to), even while we are still updating the previous mbuf slot on the ring.
This gives the prefetch much more time to resolve and get the data we need
in the cache before we need it.
In terms of performance difference, a quick sanity test using testpmd
on a Xeon (Sandy Bridge uarch) platform showed performance increases
between approx 8-18%, depending on the particular RX path used in
conjuntion with this TX path code.

While some applications may store metadata about packets in the packet
mbuf headroom, this is not a workable solution for packet metadata which
is either:
* larger than the headroom (or headroom is needed for adding pkt headers)
* needs to be shared or copied among packets
To support these use cases in applications, we reserve a general
"userdata" pointer field inside the second cache-line of the mbuf. This
is better than having the application store the pointer to the external
metadata in the packet headroom, as it saves an additional cache-line
from being used.
Apart from storing metadata, this field also provides a general 8-byte
scratch space inside the mbuf for any other application uses that are
applicable.

Overloading the 'msg_size' field in the 'arq_event_info' struct
is a bad idea. It leads to bugs when the structure is used in a
loop, since the input value (buffer size) is overwritten by the
output value (actual message length). The fix introduces one
more field of 'buf_len' for the buffer size, and renames the
field of 'msg_size' to 'msg_len' for the real message size.

Since the introduction of vector PMD, a bug in ixgbe_rxq_rearm could
cause a crash. As long as the memory pool allocated to the RX queue
has mbufs available, there is no problem. After allocation of _all_
mbufs from the memory pool, previously returned mbufs by
rte_eth_rx_burst could be accessed by subsequent calls to the PMD and
could be returned by subsequent calls to rte_eth_rx_burst. From the
perspective of the application, the means that fields within the mbuf
could change and that previously allocated mbufs could appear multiple
times.
After failure of mbuf allocation, the dd bits should indicate that the
packets are not ready. For this, this patch adds code to reset the dd
bits in the first RTE_IXGBE_DESCS_PER_LOOP packets of the next
RTE_IXGBE_RXQ_REARM_THRESH packets only if the next
RTE_IXGBE_RXQ_REARM_THRESH packets that will be accessed contain
previously allocated packets.
Setting the bits is not enough. The bits are checked _after_ setting
the mbuf fields, thus a mechanism is needed to prevent the previously
used mbuf pointers from being accessed during the speculative load of
the mbuf fields. For this reason, not only the dd bits are reset, but
also the mbufs associated to those descriptors are set to point to a
"fake" mbuf.

igb_ethdev.c contains function eth_igb_infos_get() which should set
number of tx/rx queues supported by the hardware. It contains huge

Also, there are few other places which mention i210, but not mention i211.
I didn't check it enough to say it is totally correct.
For now I see that it just able to send and receive some packets.

This method can be implemented by a poll mode driver to provide
non-standard statistics (which are not part of the generic statistics
structure). Each statistic is returned in a generic form: "name" and
"value" and can be used to dump PMD-specific statistics in the same way
than ethtool in linux kernel.
If the PMD does not provide the xstats_get and xstats_set functions, the
ethdev API will return the generic statistics in the xstats format
(name, value).
This commit opens the door for a clean-up of the generic statistics
structure, only keeping statistics that are really common to all PMDs
and moving specific ones into the xstats API.

This change splits the mbuf in two to move the pool and next pointers to
the second cache line. This frees up 16 bytes in first cache line.
The reason for this change is that we believe that there is no possible
way that we can ever fit all the fields we need to fit into a 64-byte
mbuf, and so we need to start looking at a 128-byte mbuf instead. Examples
of new fields that need to fit in, include -
* 32-bits more for filter information for support for the new filters in
the i40e driver (and possibly other future drivers)
* an additional 2-4 bytes for storing info on a second vlan tag to allow
drivers to support double Vlan/QinQ
* 4-bytes for storing a sequence number to enable out of order packet
processing and subsequent packet reordering
as well as potentially a number of other fields or splitting out fields
that are superimposed over each other right now, e.g. for the qos scheduler.
We also want to allow space for use by other non-Intel NIC drivers that may
be open-sourced to dpdk.org in the future too, where they support fields
and offloads that currently supported hardware doesn't.
If we accept the fact of a 2-cache-line mbuf, then the issue becomes
how to rework things so that we spread our fields over the two
cache lines while causing the lowest slow-down possible. The general
approach that we are looking to take is to focus the first cache
line on fields that are updated on RX , so that receive only deals
with one cache line. The second cache line can be used for application
data and information that will only be used on the TX leg. This would
allow us to work on the first cache line in RX as now, and have the
second cache line being prefetched in the background so that it is
available when necessary. Hardware prefetches should help us out
here. We also may move rarely used, or slow-path RX fields e.g. such
as those for chained mbufs with jumbo frames, to the second
cache line, depending upon the performance impact and bytes savings
achieved.

Add markers or "labels" at given points inside the mbuf which can be
used instead of individual fields to identify the start of logical
sections inside the mbuf.
The use of typedefs and dummy fields was chosen over using unions
because of a couple reasons:
* unions cause an extra level of indentation (more likely two levels as
a union containing a struct for multiple fields would be needed). This
makes the lines longer than they need to be and increases the need for
wrapping. [This was the main reason]
* with markers, you can apply multiple markers at the same point if
wanted.
