QIDs (egress/ingress) from firmware in FW_*_CMD.alloc command
can be anywhere in the range from EQ(IQFLINT)_START to EQ(IQFLINT)_END.
For eg, in the first load eqid can be from 100 to 300.
In the next load it can be from 301 to 500 (assume eq_start is 100 and eq_end is
1000).

The driver was assuming them to always start from EQ(IQFLINT)_START till
MAX_EGRQ(INGQ). This was causing stack overflow and subsequent crash.

Fixed it by dynamically allocating memory (of qsize (x_END - x_START + 1)) for
these structures.

cdc_ncm disagrees with usbnet about how much framing overhead should
be counted in the tx_bytes statistics, and tries 'fix' this by
decrementing tx_bytes on the transmit path.  But statistics must never
be decremented except due to roll-over; this will thoroughly confuse
user-space.  Also, tx_bytes is only incremented by usbnet in the
completion path.

Fix this by requiring drivers that set FLAG_MULTI_FRAME to set a
tx_bytes delta along with the tx_packets count.

Currently the usbnet core does not update the tx_packets statistic for

cdc_ncm and dependent drivers are bumping tx_packets stat on the
transmit path while asix and sr9800 aren't updating it at all.

Add a packet count in struct skb_data so these drivers can fill it
in, initialise it to 1 for other drivers, and add the packet count
to the tx_packets statistic on completion.

We occasionally see in procedure mlx4_GEN_EQE that the driver tries

This can occur in only one of two ways:
1. We are trying to generate an async event on an uninitialized slave.
2. We are trying to generate an async event on an illegal slave number
   ( < 0 or > persist->num_vfs) or an inactive slave.

To deal with #1: move the mutex initialization from specific slave init
sequence in procedure mlx_master_do_cmd to mlx4_multi_func_init() (so that
the mutex is always initialized for all slaves).

To deal with #2: check in procedure mlx4_GEN_EQE that the slave number

Statistics' state-machine in bnx2x driver must be synced with various driver
flows, but its current locking scheme manages to be wasteful [using 2 locks +
additional local variable] and prone to race-conditions at the same time,
as the state-machine and 'action' are being accessed under different locks.

In addition, current 'safe exec' isn't in fact safe, since the only guarantee
it gives is that DMA transactions are over, but ramrods might still be running.

This patch cleans up said logic, leaving us with a single lock for the entire
flow and removing the possible races.

Changes from v2:
	- Switched into mutex locking from semaphore locking.
	- Release locks on error flows.

Changes from v1:
	Failure to acquire lock fails flow instead of printing a warning and
	allowing access to the critical section.

Return EPROBE_DEFER if Regulator returns EPROBE_DEFER

If the Flexcan driver is built into kernel and a regulator is used to
enable the CAN transceiver, the Flexcan driver may not use the regulator.

When initializing the Flexcan device with a regulator defined in the device
tree, but not initialized, the regulator subsystem returns EPROBE_DEFER, hence
the Flexcan init fails.

The solution for this is to return EPROBE_DEFER if regulator is not initialized
and wait until the regulator is initialized.

Current driver code arbitrarily assumes a max outstanding tx
value of 16 parallel transmissions. Meanwhile, the device
firmware provides its actual maximum inside its reply to the
CMD_GET_SOFTWARE_INFO message.

Under heavy tx traffic, if the interleaved transmissions count
increases above the limit reported by firmware, the firmware
breaks up badly, reports a massive list of internal errors, and
the candump traces hardly matches the actual frames sent and
received.

On the other hand, in certain models, the firmware can support
up to 48 tx URBs instead of just 16, increasing the driver
throughput by two-fold and reducing the possibility of -ENOBUFs.

Thus dynamically set the driver's max tx URBs value according
to firmware replies.

Transmission of an AP beacon does not call the TX interrupt service routine,
which usually does the cleanup. Instead, cleanup is handled in a tasklet
completion routine. Unfortunately, this routine has a serious bug in that it does
not release the DMA mapping before it frees the skb, thus one IOMMU mapping is
leaked for each beacon. The test system failed with no free IOMMU mapping slots
approximately one hour after hostapd was used to start an AP.

On a MIPS Malta board, tons of fifo underflow errors have been observed
when using u-boot as bootloader instead of YAMON. The reason for that
is that YAMON used to set the pcnet device to SRAM mode but u-boot does
not. As a result, the default Tx threshold (64 bytes) is now too small to
keep the fifo relatively used and it can result to Tx fifo underflow errors.
As a result of which, it's best to setup the SRAM on supported controllers
so we can always use the NOUFLO bit.

When the driver callback returns that it's out of space for new
stations, the mac80211 IBSS code still keeps the station so it
doesn't try to add it over and over again.

Since the rate scaling algorithm is separate in mac80211, it also
invokes the rate scaling algorithm for such stations. It doesn't
know that our rate scaling algorithm is tightly integrated with
the MVM code and relies on those data structures, and it cannot
as the abstraction doesn't allow for it.

This leads to crashes when the rate scaling algorithm tries to
use uninitialized data, notably the mvmsta->vif pointer.

Protect against this in the rate scaling algorithm. We cannot get
good rates with such peers anyway since the firmware cannot do
anything with them.

The commit breaks the legacy platforms, ie. these not using device-tree,
and setting up the interrupt resources with a flag to activate edge
detection. The issue was found on the zylonite platform.

The reason is that zylonite uses platform resources to pass the interrupt number
and the irq flags (here IORESOURCE_IRQ_HIGHEDGE). It expects the driver to
request the irq with these flags, which in turn setups the irq as high edge
triggered.

After the patch, this was supposed to be taken care of with :
  irq_resflags = irqd_get_trigger_type(irq_get_irq_data(ndev->irq));

But irq_resflags is 0 for legacy platforms, while for example in
arch/arm/mach-pxa/zylonite.c, in struct resource smc91x_resources[] the
irq flag is specified. This breaks zylonite because the interrupt is not
setup as triggered, and hardware doesn't provide interrupts.

A number of tx queue wake-up events went missing due to the

                        <--
    netif_stop_queue();
}

At the end, the correct state expected is a 15 tx_urbs count
value with the tx queue state _open_. Due to the race, we get
the same tx_urbs value but with the tx queue state _stopped_.
The wake-up event is completely lost.

Thus avoid hand-rolled concurrency mechanisms and use a proper
lock for contexts and tx queue protection.
