When using INTa, ISR might be called before device is configured
for INTa [E.g., due to other device asserting the shared interrupt line],
in which case the ISR would read the SISR registers that shouldn't be
read unless HW is already configured for INTa. This might break interrupts
later on. There's also an MSI-X issue due to this difference, although
it's mostly theoretical.

This patch changes the initialization order, calling request_irq() for the
slowpath interrupt only after the chip is configured for working
in the preferred interrupt mode.

Concurrent non-blocking slowpath ramrods can be completed
out-of-order on the completion chain. Recycling completed elements,
while previously sent elements are still completion pending,
can lead to overriding of active elements on the chain. Furthermore,
sending pending slowpath ramrods currently lacks the update of the
chain element physical pointer.

This patch:
* Ensures that ramrods are sent to the FW with
  consecutive echo values.
* Handles out-of-order completions by freeing only first
  successive completed entries.
* Updates the chain element physical pointer when copying
  a pending element into a free element for sending.

In case of a tx queue timeout every transmit is blocked until the

There is a memleak when suspend/resume this driver version.
Currently the stmmac, during resume step, reallocates all the resources
but they are not released when suspend.
The patch is not to release these resources but the logic has been changed.
In fact, it is not necessary to free and reallocate all from scratch
because the memory data will be always preserved.
As final solution, the patch just reinit the descriptors and the rx/tx
pointers only when resume. Tested done on STi boxes.

If the driver were to happen to have a mutex held while
the i40e_init_adminq call was called, the init_adminq might
inadvertently call mutex_init on a lock that was held
which is a violation of the calling semantics.

Fix this by avoiding adminq.c code allocating/freeing this memory, and
then do the same work only once in probe/remove.

Testing Hints (Required if no HSD): for VF, load i40evf in bare metal
and echo 32 > sriov_numvfs; echo 0 > sriov_numvfs in a loop.  Yes this
is a horrible thing to do.

Enabling SR-IOV and then bringing the interface up was resulting in the PF
MAC addresses getting into a bad state.  Specifically the MAC address was
enabled for both VF 0 and the PF.  This resulted in some odd behaviors such
as VF 0 receiving a copy of the PFs traffic, which in turn enables the
ability for VF 0 to spoof the PF.

A workaround for this issue appears to be to bring up the interface first
and then enable SR-IOV as this way the reset is then triggered in the
existing code.

In order to correct this I have added a change to ixgbe_setup_tc where if
the interface is down we still will at least call ixgbe_reset so that the
MAC addresses for the device are reset to the correct pools.

Steps to reproduce issue:
modprobe ixgbe
echo 7 > /sys/bus/pci/devices/0000\:01\:00.1/sriov_numvfs
ifconfig enp1s0f1 up
ethregs -s 1:00.1 | grep MPSAR | grep -v 00000000

Result:
	MPSAR[0]               00000081
	MPSAR[254]             00000001

Expected Result, behavior after patch:
	MPSAR[0]               00000080
	MPSAR[254]             00000080

The existing ndo_set_mac_address only copies the new MAC addr
and didn't set the new MAC addr to the HW. The correct way is
to delete the existing default MAC filter from HW and add

default mac filter l2 context, the driver must go thru
close_nic() to delete the default MAC and RFS filters, then
open_nic() to set the default MAC address to HW.

If the driver is used on an ARM platform with SPARSE_IRQ defined,
semantics of NR_IRQS is different (minimal value of virtual irqs) and
by default it is set to 16, see arch/arm/include/asm/irq.h.

This value may be less than the actual number of virtual irqs, which
may break the driver initialization. The check removal allows to use
the driver on such a platform, and, if irq controller driver works
correctly, the check is not needed on legacy platforms.
