This reverts commit d2d2d87dfd
("bnx2x: allow nvram test to run when device is down").
Since it makes access to the device in D3 state possible.
More work is required to make sure device is not set to D3
during ifdown. Until this is done the nvram-test should simply
exit if device is down like it did before.

With the commit a11fbba (net/cpsw: fix irq_disable() with threaded interrupts)
from Sebastian Siewior, a kernel warning is generated as below. This warning
is generated as the irq_enabled is not initialized for the primary interface
and in probe it is initialized for the second interface. This patch moves
irq_enabled initialization from second interface to primary interface.

The venerable 3c509 driver only sets its device parent in one case, the ISAPnP one.
It does this with the SET_NETDEV_DEV function. It should register with the device
hierarchy in two additional cases: standard (non-PnP) ISA and EISA.
- Currently they appear here:
/sys/devices/virtual/net/eth0 (standard ISA)
/sys/devices/virtual/net/eth1 (EISA)
- Rather, they should instead be here:
/sys/devices/isa/3c509.0/net/eth0 (standard ISA)
/sys/devices/pci0000:00/0000:00:07.0/00:04/net/eth1 (EISA)

Fixed: warning: cast from pointer to integer of different size
The Hyper-V hosts always use 64 bit request id. The guests can have 32 or 64
bit pointers which equal to the ulong type size. So we cast it to ulong type.
And, assigning 32bit integer to 64 bit variable works fine.
The VMBus returns the same id in the completion packet. But the value has no
effect on the host side.

Pegasus driver used single callback for sync and async control URBs.
Special flags were employed to distinguish between both, but due to flawed
logic it didn't always work. As a result of this change
[get|set]_registers() are now much simpler. Async write is also leaner
and does not use single, statically allocated memory for usb_ctrlrequest,
which is another potential race when asynchronously submitting URBs.

Jeff Kirsher says:
====================
This series contains updates to e1000e, igb and ixgbe.
There are 2 patches in this series which could be applied to net,
but since Linus is so very close to releasing 3.9, I do not think
it prudent to try and push these into net at this time. I have CC'd
stable on these patches so that they can queue them up as soon as
3.9 gets released.
The 2 patches are:
e1000e: fix numeric overflow in phc settime method
ixgbe: fix EICR write in ixgbe_msix_other
Richard provides a fix for e1000e by using a helper function from time.h
to resolve a unintended overflow in the PTP settime function.
Bruce provides a fix to wait for NAPI to be done with the current context
after disabling interrupts and then disable NAPI when the interface
is going down. This fixes a possible "unable to handle kernel paging
request" panic in net-next.
Andi Kleen provides a patch for igb to use mdelay instead of udelay
when we needed 100000us.
Jacob provides a fix for ixgbe to simply mask the lower 16bits off so that
ixgbe_msix_other does not write them in the EICR, which causes them to
remain high and be properly handled by the clean_rings interrupt routine
as normal.
Emil cleans up the logic in ixgbe_setup_loopback_test() to only access
registers applicable to the MAC type. In addition, removes majority
of the AUTOC register reads by using a cached value instead to avoid
writing corrupted values to AUTOC due to bad FW. Emil also add support
for disabling link during boot time. Lastly, he provides a patch which
adds the MAC type to the version in ethtool_regs which will make it
easier to check the MAC type when dumping registers with ethtool.
There is a separate ethtool tool patch which is dependent upon Emil's
last patch of the series to add the MAC type to the version in
ethtool_regs, which will be sent separately.
