d87ba24d1a net/cxgbe: fix rxq default params for ports under same PF
Enabling rx queues with default interrupt parameters doesn't happen
for other ports under same PF due to FULL_INIT_DONE flag being set
by the first port.

Fix is to to allow each port to enable its own rx queues with default
parameters.

6c2809628c net/cxgbe: improve latency for slow traffic
TX coalescing waits for ETH_COALESCE_PKT_NUM packets to be coalesced
across bursts before transmitting them.  For slow traffic, such as
100 PPS, this approach increases latency since packets are received
one at a time and tx coalescing has to wait for ETH_COALESCE_PKT
number of packets to arrive before transmitting.

To fix this:

- Update rx path to use status page instead and only receive packets
  when either the ingress interrupt timer threshold (5 us) or
  the ingress interrupt packet count threshold (32 packets) fires.
  (i.e. whichever happens first).

- If number of packets coalesced is <= number of packets sent
  by tx burst function, stop coalescing and transmit these packets
  immediately.

Also added compile time option to favor throughput over latency by
default.

- virtio and mlx* use RTE_INIT directly as they have custom initialization

- VDEV devices are not modified - they continue to use PMD_REGISTER_DRIVER.

001a1c0f98 ethdev: get registers width
The ethtool app was allocating too little space for 64-bit
registers which resulted in memory corruption.

Removes hard-coded assumption that device registers
are always 32 bits wide. The rte_eth_dev_get_reg_length
and rte_eth_dev_get_reg_info callbacks did not
provide register size to the app in any way while is
needed to allocate correct number of bytes before
retrieving registers using rte_eth_dev_get_reg.

This commit changes rte_eth_dev_get_reg_info so that
it can be used to retrieve both the number of registers
and their width, and removes the now-redundant
rte_eth_dev_get_reg_length.

cb6696d220 drivers: update registration macro usage
Modify the PMD_REGISTER_DRIVER macro, adding a name argument to it.  The
addition of a name argument creates a token that can be used for subsequent
macros in the creation of unique symbol names to export additional bits of
information for use by the pmdinfogen tool.  For example:

PMD_REGISTER_DRIVER(ena_driver, ena);

registers the ena_driver struct as it always did, and creates a symbol
const char this_pmd_name0[] __attribute__((used)) = "ena";

which pmdinfogen can search for and extract.  The subsequent macro

DRIVER_REGISTER_PCI_TABLE(ena, ena_pci_id_map);

creates a symbol const char ena_pci_tbl_export[] __attribute__((used)) =
"ena_pci_id_map";

Which allows pmdinfogen to find the pci table of this driver

Using this pattern, we can export arbitrary bits of information.

pmdinfo uses this information to extract hardware support from an object
file and create a json string to make hardware support info discoverable
later.

6b6861c171 ethdev: check queue state before starting or stopping
Following the same approach taken with dev_started field
in rte_eth_dev_data structure, this patch adds two new fields
in it, rx_queue_state and tx_queue_state arrays, which track
which queues have been started and which not.

This is important to avoid trying to start/stop twice a queue,
which will result in undefined behaviour
(which may cause RX/TX disruption).

Mind that only the PMDs which have queue_start/stop functions
have been changed to update this field, as the functions will
check the queue state before switching it.
