The original core reset and disable routines do not work always
on running system. These routines were updated to properly reset
a core. When module is unloaded the device is put into download
state where all necessary cores have been reset. This will make
sure the device is in idle mode after module unload.

To avoid head of line blocking in the event a VF stops cleaning Rx descriptors

To avoid a situation where the head write-back registers can remain set ofter
the driver is unloaded he clears them on a VF reset.

====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The Tx head write-back registers are not cleared during an FLR or VF reset.
As a result a configuration that had head write-back enabled can leave the
registers set after the driver is unloaded. If the next driver loaded doesn't
use the write-back registers this can lead to a bad configuration where
head write-back is enabled, but the driver didn't request it.
To avoid this situation the PF should be resetting the Tx head write-back
registers when the VF requests a reset.

Refactor the deletion/update of prefix routes when removing an
address. Now also consider IFA_F_NOPREFIXROUTE and if there is an address
present with this flag, to not cleanup the route. Instead, assume
that userspace is taking care of this route.
Also perform the same cleanup, when userspace changes an existing address
to add NOPREFIXROUTE (to an address that didn't have this flag). This is
done because when the address was added, a prefix route was created for it.
Since the user now wants to handle this route by himself, we cleanup this
route.
This cleanup of the route is not totally robust. There is no guarantee,
that the route we are about to delete was really the one added by the
kernel. This behavior does not change by the patch, and in practice it
should work just fine.

The bnx2x driver in its pci shutdown() callback releases its pci bars (in the
same manner it does during its pci remove() callback).
During a system reboot while VFs are enabled, its possible for the VF's remove
to be called (as a result of pci_disable_sriov()) after its shutdown callback
has already finished running; This will cause a paging request fault as the VF
tries to access the pci bar which it has previously released, crashing the
system.
This patch further differentiates the shutdown and remove callbacks, preventing the
pci release procedures from being called during shutdown.
