dadff13793 net/sfc: support encap flow items in transfer rules
Add support for flow items VXLAN, Geneve and NVGRE to
MAE-specific RTE flow implementation.

Having support for these items implies the ability to insert
so-called outer MAE rules and refer to them in MAE action rules.
The patch takes care of all necessary facilities to do that.

In a pattern, a L2 item preceding an item VLAN must have
correct "type" ("inner_type") set depending on the total

"pattern eth type is X / vlan / end",
X = 0x8100, or 0x88a8, or 0x9100, or 0x9200, or 0x9300

"pattern eth type is X / vlan inner_type is 0x8100 / vlan / end"

1e7fbdf0ba net/sfc: support concept of switch domains/ports
A later patch will add support for RTE flow action PORT_ID
to MAE backend. The driver has to ensure that such actions
refer to RTE ethdev instances deployed on top of the same
physical device. Also, the driver needs a means to find
sibling RTE ethdev instances when parsing such actions.

In order to solve these problems, add a switch infrastructure
which allocates switch domains based on persistence of device
serial number string across switch ports included in a domain.
Explain mapping between RTE switch port IDs and MAE endpoints.

f30e69b41f ethdev: add device flag to bypass auto-filled queue xstats
Queue stats are stored in 'struct rte_eth_stats' as array and array size
is defined by 'RTE_ETHDEV_QUEUE_STAT_CNTRS' compile time flag.

As a result of technical board discussion, decided to remove the queue
statistics from 'struct rte_eth_stats' in the long term.

Instead PMDs should represent the queue statistics via xstats, this
gives more flexibility on the number of the queues supported.

Currently queue stats in the xstats are filled by ethdev layer, using
some basic stats, when queue stats removed from basic stats the
responsibility to fill the relevant xstats will be pushed to the PMDs.

During the switch period, temporary 'RTE_ETH_DEV_AUTOFILL_QUEUE_XSTATS'
device flag is created. Initially all PMDs using xstats set this flag.
The PMDs implemented queue stats in the xstats should clear the flag.

When all PMDs switch to the xstats for the queue stats, queue stats
related fields from 'struct rte_eth_stats' will be removed, as well as
'RTE_ETH_DEV_AUTOFILL_QUEUE_XSTATS' flag.
Later 'RTE_ETHDEV_QUEUE_STAT_CNTRS' compile time flag also can be
removed.
