rte_eth_ctrl.h. It is slightly higher level and as a result relies more on
PMDs to process and validate flow rules.

Benefits:

- A unified API is easier to program for, applications do not have to be
  written for a specific filter type which may or may not be supported by
  the underlying device.

- The behavior of a flow rule is the same regardless of the underlying
  device, applications do not need to be aware of hardware quirks.

- Extensible by design, API/ABI breakage should rarely occur if at all.

- Documentation is self-standing, no need to look up elsewhere.

Existing filter types will be deprecated and removed in the near future.

net/bonding: reconfigure all slave queues every time

This reverts commit 5b7bb2bda5519b7800f814df64d4e015282140e5.

It is necessary to reconfigure all queues every time because configuration
can be changed.

For example, if we're reconfiguring bonding device with new memory pool,
already configured queues will still use the old one. And if the old
mempool be freed, application likely will panic in attempt to use
freed mempool.

This happens when we use the bonding device with OVS 2.6 while MTU
reconfiguration:

eal: postpone vdev initialization

Some platform like octeontx may use pci and
vdev based combined device to represent a logical
dpdk functional device.In such case, postponing the
vdev initialization after pci device
initialization will provide the better view of
the pci device resources in the system in
vdev's probe function, and it allows better
functional subsystem registration in vdev probe
function.

As a bonus, This patch fixes a bond device
initialization use case.

example command to reproduce the issue:
./testpmd -c 0x2  --vdev 'eth_bond0,mode=0,
slave=0000:02:00.0,slave=0000:03:00.0' --
--port-topology=chained

root cause:
In existing case(vdev initialization and then pci
initialization), creates three Ethernet ports with
following port ids
0 - Bond device
1 - PCI device 0
2 - PCI devive 1

Since testpmd, calls the configure/start on all the ports on
start up,it will translate to following illegal setup sequence

1)bond device configure/start
1.1) pci device0 stop/configure/start
1.2) pci device1 stop/configure/start
2)pci device 0 configure(illegal setup case,
as device in start state)

The fix changes the initialization sequence and
allow initialization in following valid setup order
1) pcie device 0 configure/start
2) pcie device 1 configure/start
3) bond device 2 configure/start

ethdev: check maximum number of queues for statistics

Arrays inside rte_eth_stats have size=RTE_ETHDEV_QUEUE_STAT_CNTRS.
Some devices report more queues than that and this code blindly uses
the reported number of queues by the device to fill those arrays up.
This patch fixes the problem using MIN between the reported number of
queues and RTE_ETHDEV_QUEUE_STAT_CNTRS.

7 years agolog: do not drop debug logs at compile time
Olivier Matz [Wed, 23 Nov 2016 15:34:25 +0000 (16:34 +0100)]
log: do not drop debug logs at compile time

Today, all logs whose level is lower than INFO are dropped at
compile-time. This prevents from enabling debug logs at runtime using
--log-level=8.

The rationale was to remove debug logs from the data path at
compile-time, avoiding a test at run-time.

This patch changes the behavior of RTE_LOG() to avoid the compile-time
optimization, and introduces the RTE_LOG_DP() macro that has the same
behavior than the previous RTE_LOG(), for the rare cases where debug
logs are in the data path.

So it is now possible to enable debug logs at run-time by just
specifying --log-level=8. Some drivers still have special compile-time
options to enable more debug log. Maintainers may consider to
remove/reduce them.

pmdinfogen: fix endianness with cross-compilation

pmdinfogen has a bug in which, during build, it pulls in rte_byteorder.h to
obtain the rte macros for byteswapping between the cpu byte order and big or
little endian.  Unfortunately, pmdinfogen is a tool that is only meant to be run
during the build of dpdk components, and so, it runs on the host.  In cross
compile environments however, the rte_byteorder.h is configured using a target
cpu, who's endianness may differ from that of the host, leading to improper
swapping.

The fix is to use host system defined byte swapping routines rather than the
dpdk provided routines.  Note that we are using non posix compliant routines, as
the posix compliant api only addresses 16 and 32 bit swaps, and we also need 64
bit swaps.  Those macros exist (via endian.h), but BSD and Linux put that header
in different locations so some ifdeffery is required.

Tested successfully by myself on Linux and BSD systems.
