Don't call bnx2x_link_status_update() from bnx2x_link_update().
Actual use case of bnx2x_link_status_update() is to update the link
status in shared memory between driver and MFW, and not to get the
link status from HW.
So ideally, bnx2x_link_status_update() should be called when there
is an actual link event or change in link status.
Calling bnx2x_link_status_update() from bnx2x_link_update() may
corrupt the data of link status in shared memory and result
in inconsistent state of link.

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.

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

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.

The function rte_eth_xstats_get() return an array of tuples (id,
value). The value is the statistic counter, while the id references a
name in the array returned by rte_eth_xstats_get_name().
Today, each 'id' returned by rte_eth_xstats_get() is equal to the index
in the returned array, making this value useless. It also prevents a
driver from having different indexes for names and value, like in the
example below:
rte_eth_xstats_get_name() returns:
0: "rx0_stat"
1: "rx1_stat"
2: ...
7: "rx7_stat"
8: "tx0_stat"
9: "tx1_stat"
...
15: "tx7_stat"
rte_eth_xstats_get() returns:
0: id=0, val=<stat> ("rx0_stat")
1: id=1, val=<stat> ("rx1_stat")
2: id=8, val=<stat> ("tx0_stat")
3: id=9, val=<stat> ("tx1_stat")
This patch fixes the drivers to set the 'id' in their ethdev->xstats_get()
(except e1000 which was already doing it), and fixes ethdev by not setting
the 'id' field to the index of the table for pmd-specific stats: instead,
they should just be shifted by the max number of generic statistics.
