Update the strings used for presenting stats to adhere
to the scheme previously presented. Updated xstats_get()
function to handle Q information only if xstats() is not
implemented in the PMD, providing the PMD with the needed
flexibility to expose its extended Q stats.
Add extended statistic section to the programmers
guide, poll mode driver section. This section describes
how the strings stats are formatted, and how the client
code can use this to gather information about the stat.

With fixed avail ring, we don't need to get desc idx from avail ring.

In DPDK based switching environment, mostly vhost runs on a dedicated core
while virtio processing in guest VMs runs on different cores.
Take RX for example, with generic implementation, for each guest buffer,
a) virtio driver allocates a descriptor from free descriptor list
b) modify the entry of avail ring to point to allocated descriptor
c) after packet is received, free the descriptor
When vhost fetches the avail ring, it need to fetch the modified L1 cache from
virtio core, which is a heavy cost in current CPU implementation.
This idea of this optimization is:
allocate the fixed descriptor for each entry of avail ring, so avail ring will
always be the same during the run.
This removes L1M cache transfer from virtio core to vhost core for avail ring.
(Note we couldn't avoid the cache transfer for descriptors).
Besides, descriptor allocation and free operation is eliminated.
This also makes vector procesing possible to further accelerate the processing.
This is the layout for the avail ring(take 256 ring entries for example), with
each entry pointing to the descriptor with the same index.
avail
idx

| 0 | 1 | 2 | | 254 | 255 | used ring

This is the ring layout for TX.
As we need one virtio header for each xmit packet, we have 128 slots available.

Bonding device implements independent management of RSS settings. It
stores its own copies of settings i.e. RETA, RSS hash function and RSS
key. It’s required to ensure consistency.
1) RSS hash function set for bonding device is maximal set of RSS hash
functions supported by all bonded devices. That mean, to have RSS support
for bonding, all slaves should be RSS-capable.
2) RSS key is propagated over the slaves "as is".
3) RETA for bonding is an internal table managed by bonding API, and is
used as a pattern to set up slaves. Its size is GCD of all RETA sizes, so
it can be easily used as a pattern providing expected behavior, even if
slaves RETA sizes are different.

Comparing with the older NICs, x550's RSS redirection table is enlarged to 512
entries. As the original code is for the NICs which have a 128 entries RSS table,
it means only part of the RSS table is set on x550. So, RSS cannot work as
expected on x550, it doesn't redirect the packets evenly.
This patch configs the entries beyond 128 on x550 to let RSS work well, and also
update the query and update functions to support 512 entries.
