PMD sets up and clears the slow path interrupt status block in dev_start
and dev_stop flow and slow path interrupt status block DMA memory for
device is allocated in dev_configure flow.
This situation creates a state where, after dev_stop is called, and if
there is a slow path interrupt from device, PMD sees the old value of
status block consumer in dev_start flow, since DMA memory for status
block belongs to old configuration and dev_start will result in
new slow path interrupt status block configuration.
And since PMD fails to ack new slow path interrupt with correct status
block consumer value, device continues to trigger interrupt causing an
interrupt flood.
Fix is to create and destroy status block DMA memory in dev_start and
dev_stop flow instead of dev_configure and dev_close flow.

Patch "8bd31421c593 ("net/bnx2x: fix ramrod timeout")"
introduced a regression where sc->scan_fp flags is
set for unexpectedly long time. So the slow path completion
handler flow is run unnecessarily which walks over receive
descriptor ring of fast path and drops the data packets while looking
for slow path completion descriptor out of fast path ring.
This issue is seen under heavy traffic with link events happening
in background.

The periodic callout function and the interrupt handler both modify the
periodic flags. There is a possible race condition when an application
is going through dev_stop()/dev_start() and an interrupt handler is
invoked. We also need to ensure that periodic polling is not invoked in
interrupt context.
This patch handles such case by using separate variable to check for
interrupt context. Also, atomically load and store the periodic flag
value.

In some cases, DPDK application may send packets
while PMD is going through load or unload flow.
This causes firmware to access invalid/unallocated
memory to process transmit buffer. Which results in
error on PCI bus and chip further blocks access to host,
causing a DMAE timeout.
Fix this issue by installing dummy empty transmit and receive
handlers at the beginning of unload path (rte_eth_dev_stop())
and install actual transmit and receive handlers after successful
load of the PMD port (rte_eth_dev_start()). This way, application
won't be able to send packets while device is going through
load/unload flow.

There is a race condition while processing RAMROD
completion in fast path queue through interrupt handler
and polling method.
Interrupt handler invoked from actual interrupt event
and from RAMROD processing polling flow may create a
situation where one flow will read and clear a fastpath
interrupt without actually processing the RAMROD completion.
Thus, causing a RAMROD timeout even though HW sent an
completion event.
Fix this by introducing an atomic variable which will be
set only when interrupt handler needs to process RAMROD
completion.

Whenever possible (if the library ships a pkg-config file) use meson's
dependency() function to look for it, as it will automatically add it
to the Requires.private list if needed, to allow for static builds to
succeed for reverse dependencies of DPDK. Otherwise the recursive
dependencies are not parsed, and users doing static builds have to
resolve them manually by themselves.
When using this API avoid additional checks that are superfluous and
take extra time, and avoid adding the linker flag manually which causes
it to be duplicated.
