740feaf349 ethdev: remove driver name from device private data
rte_driver->name has the driver name and all physical and virtual
devices has access to it.

Previously it was not possible for virtual ethernet devices to access
rte_driver->name field (because eth_dev used to keep only pci_dev),
and it was required to save driver name in the device private struct.

After re-works on bus and vdev, it is possible for all bus types to
access rte_driver.

It is able to remove the driver name from ethdev device private data and
use eth_dev->device->driver->name.

rmb before determining rsp_type is a bottleneck.

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.

feb9f680cd mk: optimize directory dependencies
Before this patch, the management of dependencies between directories
had several issues:

- the generation of .depdirs, done at configuration is slow: it can take
  more than one minute on some slow targets (usually ~10s on a standard
  PC without -j).

- for instance, it is possible to express a dependency like:
  - app/foo depends on lib/librte_foo
  - and lib/librte_foo depends on app/bar
  But this won't work because the directories are traversed with a
  depth-first algorithm, so we have to choose between doing 'app' before
  or after 'lib'.

- the script depdirs-rule.sh is too complex.

- we cannot use "make -d" for debug, because the output of make is used for
  the generation of .depdirs.

This patch moves the DEPDIRS-* variables in the upper Makefile, making
the dependencies much easier to calculate. A DEPDIRS variable is still
used to process library dependencies in LDLIBS.

After this commit, "make config" is almost immediate.

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.
