The default mask used by PMDs for the VLAN pattern when one isn't provided

TPID handling in rte_flow VLAN and E_TAG pattern item definitions is not
consistent with the normal stacking order of pattern items, which is
confusing to applications.

Problem is that when followed by one of these layers, the EtherType field
of the preceding layer keeps its "inner" definition, and the "outer" TPID
is provided by the subsequent layer, the reverse of how a packet looks like

 rte_flow: [ ETH EtherType = B | VLAN TPID = A | B DATA ]

Worse, when QinQ is involved, the stacking order of VLAN layers is
unspecified. It is unclear whether it should be reversed (innermost to
outermost) as well given TPID applies to the previous layer:

 Wire:       [ ETH TPID = A | VLAN TPID = B | VLAN EtherType = C | C DATA ]

While specifying EtherType/TPID is hopefully rarely necessary, the stacking
order in case of QinQ and the lack of documentation remain an issue.

This patch replaces TPID in the VLAN pattern item with an inner
EtherType/TPID as is usually done everywhere else (e.g. struct vlan_hdr),

RSS hash types (ETH_RSS_* macros defined in rte_ethdev.h) describe the
protocol header fields of a packet that must be taken into account while
computing RSS.

When facing encapsulated (e.g. tunneled) packets, there is an ambiguity as
to whether these should apply to inner or outer packets. Applications need
the ability to tell exactly "where" RSS must be performed.

This is addressed by adding encapsulation level information to the RSS flow
action. Its default value is 0 and stands for the usual unspecified
behavior. Other values provide a specific encapsulation level.

Contrary to the change announced by commit 676b605182a5 ("doc: announce

struct rte_eth_rss_conf but struct rte_flow_action_rss as the former is not

ethdev: remove experimental flag of ports enumeration

The basic operations for ports enumeration should not be
considered as experimental in DPDK 18.05.

The iterator RTE_ETH_FOREACH_DEV was introduced in DPDK 17.05.
It uses the function the rte_eth_find_next_owned_by() to get
only ownerless ports. Its API can be considered stable.
So the flag experimental is removed from rte_eth_find_next_owned_by().

The flag experimental is removed from rte_eth_dev_count_avail()
which is the new name of the old function rte_eth_dev_count().

The flag experimental is set to rte_eth_dev_count_total()
in the .c file for consistency with the declaration in the .h file.

A lot of internal applications are fixed to not allow experimental API.

net/mlx4: fix ignored RSS hash types

When an unsupported hash type is part of a RSS configuration structure, it
is silently ignored instead of triggering an error. This may lead
applications to assume that such types are accepted, while they are in fact
not part of the resulting flow rules.

net/thunderx: fix MTU configuration for jumbo packets

thunderx pmd driver passes dev_info.max_rx_pktlen as
9200 (via rte_eth_dev_info_get()) to application.
But, when application tries to set MTU as
(9200 - sizeof(ethernet_header_t)) the operation fails
because of missing CRC and VLAN additions.

This patch fixes the following for thunderx pmd driver:
 - Sets NIC_HW_MAX_FRS to 9216 (instead of 9200)
 - Sets NIC_HW_MAX_MTU to 9190 (NIC_HW_MAX_FRS - ETH_HLEN
   - ETHER_CRC_LEN - 2*VLAN_HLEN)
 - Sets dev_info->max_rx_pkt_len to NIC_HW_MAX_MTU +
   ETH_HLEN (instead of 9200)
 - Allows rte_eth_dev_set_mtu() to pass if application
   (like VPP) calls rte_eth_dev_set_mtu() before
   rte_eth_dev_start() by putting appropriate check for
   dev->data->dev_started
