e0c103a79c net/bnx2x: fix reading VF id
The logic to read vf_id used by ACQUIRE/TEARDOWN_Q/RELEASE TLVs,
multiplexed return value to convey vf_id value and status of read vf_id
API. This lets to segfault at dev_start() as resources are not properly
cleaned and re-allocated.

Fix read vf_id API to differentiate between vf_id value and return
status. Adjust the status checking accordingly.
Added bnx2x_vf_teardown_queue() API and moved relevant code from
bnx2x_vf_unload() to new API.

6bee9d5f45 drivers/net: use ack in interrupt handlers
Replace rte_intr_enable() with rte_intr_ack() API
for acking an interrupt in interrupt handlers and
rx_queue_intr_enable() callbacks of PMD's.

This is inline with original intent of this change in PMDs
to ack interrupts after handling is completed if
device is backed by UIO, IGB_UIO or VFIO(with INTx).

a159730c2f eal: add ack interrupt API
Add new ack interrupt API to avoid using
VFIO_IRQ_SET_ACTION_TRIGGER(rte_intr_enable()) for
acking interrupt purpose for VFIO based interrupt handlers.
This implementation is specific to Linux.

Using rte_intr_enable() for acking interrupt has below issues

 * Time consuming to do for every interrupt received as it will
   free_irq() followed by request_irq() and all other initializations
 * A race condition because of a window between free_irq() and
   request_irq() with packet reception still on and device still
   enabled and would throw warning messages like below.
   [158764.159833] do_IRQ: 9.34 No irq handler for vector

In this patch, rte_intr_ack() is a no-op for VFIO_MSIX/VFIO_MSI interrupts
as they are edge triggered and kernel would not mask the interrupt before
delivering the event to userspace and we don't need to ack.

33543fb3b6 vfio: revert interrupt eventfd setup at probe
This reverts commit 89aac60e0b.
"vfio: fix interrupts race condition"

The above mentioned commit moves the interrupt's eventfd setup
to probe time but only enables one interrupt for all types of
interrupt handles i.e VFIO_MSI, VFIO_LEGACY, VFIO_MSIX, UIO.
It works fine with default case but breaks below cases specifically
for MSIX based interrupt handles.

* Applications like l3fwd-power that request rxq interrupts
  while ethdev setup.
* Drivers that need > 1 MSIx interrupts to be configured for
  functionality to work.

VFIO PCI for MSIx expects all the possible vectors to be setup up
when using VFIO_IRQ_SET_ACTION_TRIGGER so that they can be
allocated from kernel pci subsystem. Only way to increase the number
of vectors later is first free all by using VFIO_IRQ_SET_DATA_NONE
with action trigger and then enable new vector count.

Above commit changes the behavior of rte_intr_[enable|disable] to
only mask and unmask unlike earlier behavior and thereby
breaking above two scenarios.

bbe29a9bd7 eal/linux: select IOVA as VA mode for default case
When bus layer reports the preferred mode as RTE_IOVA_DC then
select the RTE_IOVA_VA mode:

- All drivers work in RTE_IOVA_VA mode, irrespective of physical
address availability.

- By default, a mempool asks for IOVA-contiguous memory using
RTE_MEMZONE_IOVA_CONTIG. This is slow in RTE_IOVA_PA mode and it
may affect the application boot time.

b76fafb174 eal: fix IOVA mode selection as VA for PCI drivers
The incriminated commit broke the use of RTE_PCI_DRV_IOVA_AS_VA which
was intended to mean "driver only supports VA" but had been understood
as "driver supports both PA and VA" by most net drivers and used to let
dpdk processes to run as non root (which do not have access to physical
addresses on recent kernels).

The check on physical addresses actually closed the gap for those
drivers. We don't need to mark them with RTE_PCI_DRV_IOVA_AS_VA and this
flag can retain its intended meaning.
Document explicitly its meaning.

We can check that a driver requirement wrt to IOVA mode is fulfilled
before trying to probe a device.

Finally, document the heuristic used to select the IOVA mode and hope
that we won't break it again.

62f8f5ace5 bus/pci: remove Mellanox kernel driver type
This reverts commit 0cb86518db.

The PCI bus now reports DC when faced with a device bound to an unknown
driver and, in such a case, the IOVA mode is selected against physical
address availability.

As a consequence, there is no reason for this special case for Mellanox
drivers.

3a690d5a65 examples/ipsec-secgw: fix first packet with inline crypto
Inline crypto installs a flow rule in the NIC. This flow
rule must be installed before the first inbound packet is
received.

The create_session() function installs the flow rule,
create_session() has been refactored into create_inline_session()
and create_lookaside_session(). The create_inline_session() function
uses the socket_ctx data and is now called at initialisation in
sa_add_rules().

The max_session_size() function has been added to calculate memory
requirements.

The cryprodev_init() function has been refactored to drop calls to
rte_mempool_create() and to drop calculation of memory requirements.

The main() function has been refactored to call max_session_size() and
to call session_pool_init() and session_priv_pool_init() earlier.
The ports are started now before adding a flow rule in main().
The sa_init(), sp4_init(), sp6_init() and rt_init() functions are
now called after the ports have been started.

The rte_ipsec_session_prepare() function is called in fill_ipsec_session()
for inline which is called from the ipsec_sa_init() function.

316095eb41 lpm: use atomic store to avoid partial update
Compiler could generate non-atomic stores for whole table entry
updating. This may cause incorrect nexthop to be returned, if
the byte with valid flag is updated prior to the byte with nexthop
is updated.
Besides, field by field updating of table entries follow
read-modify-write sequences. The operations are not atomic,
nor efficient. And could cause entries out of synchronization.

Changed to use atomic store to update whole table entry.

be8c9ad0c2 lpm: avoid race conditions for v20
When a tbl8 group is getting attached to a tbl24 entry, lookup
might fail even though the entry is configured in the table.

For ex: consider a LPM table configured with 10.10.10.1/24.
When a new entry 10.10.10.32/28 is being added, a new tbl8
group is allocated and tbl24 entry is changed to point to
the tbl8 group. If the tbl24 entry is written without the tbl8
group entries updated, a lookup on 10.10.10.9 will return
failure.

Correct memory orderings are required to ensure that the
store to tbl24 does not happen before the stores to tbl8 group
entries complete.

Besides, explicit structure alignment is used to address atomic
operation building issue with older version clang.
