It is about using rcu_dereference() when not in a rcu-locked section. It only
happens on initialization hence fix the initialization to not rcu_dereference()

Currently the SMSC911X driver may only be built for a specific set of
architectures, being limited to do so by a Kconfig depends line. This
means that if a platform wishes to use the driver, its architecture must
be added to the list explicitly, introducing pointless churn.
This may have been due to the driver's use of the {read,write}s{b,w,l}
functions, which have since been replaced with the more standard
io{read,write}{8,16,32}_rep. We can instead depend on HAS_IOMEM, which
should prevent build issues while allowing the driver to be built for
currently unlisted architectures, including x86 and arm64.
This patch removes the explicit list of architectures from the driver's
depend line, and replaces it with a dependency on HAS_IOMEM.

Removing some boilerplate by using module_pci_driver instead of calling
register and unregister in the otherwise empty init/exit functions.
The name of the pci_driver struct had to be changed in order to prevent
a build failure.

In order to support a more accurate check for a PTP Rx hang where the
device can no longer timestamp received packets, we need to update, per
ring, when the last Rx timestamp was. Because of how the PTP Rx hang logic
works, the current logic is valid, but properly updating the ring variable
increases the accuracy of the check.

This patch fixes the issue of unlocking swflag_mutex for 82574 and 82583
devices regardless of if the hw semaphore has been successfully acquired via
e1000_get_hw_semaphore_82574(). With this patch, unlocking mutex now depends
on if the hw semaphore was successfully acquired before. And 82574/82583
devices are reset regardless of whether e1000_get_hw_semaphore_82574()
returns success or failure.

There is currently no way for an Ethernet MAC driver servicing PHY link
interrupts to notify this to the PHY state machine without defining its
own state machine. Since most drivers are not so special, introduce a
helper: phy_mac_interrupt() which can be called from a link up/down
interrupt routine to update the PHY state machine. To avoid code
duplication some refactoring has been done to expose the workqueue and
its corresponding callback internally.

When a PHY device is registered with the special IRQ value
PHY_IGNORE_INTERRUPT (-2) it will not properly be handled by the PHY
library:
- it continues to poll its register, while we do not want this
because such PHY link events or register changes are serviced by an
Ethernet MAC
- it will still try to configure PHY interrupts at the PHY level, such
interrupts do not exist at the PHY but at the MAC level
- the state machine only handles PHY_POLL, but should also handle
PHY_IGNORE_INTERRUPT similarly
This patch updates the PHY state machine and initialization paths to
account for the specific PHY_IGNORE_INTERRUPT. Based on an earlier patch
by Thomas Petazzoni, and reworked to add the missing bits. Add a helper
phy_interrupt_is_valid() which specifically tests for a PHY interrupt
not to be PHY_POLL or PHY_IGNORE_INTERRUPT and use it throughout the
code.

Failure of the UCAST set for base mac address fails when user configures a
duplicate mac address that matches that of another vNIC on the same port.
The bna does not handle the ucast failure and keeps this address in cache.
On disable of the vNIC, bna tries to delete the failed base mac address and the
fw asserts.
On failure of ucast address, mark ucast address set to false.

bnx2x_set_features() forces a driver reload if GRO setting is changed.
A reload makes the ethernet port unresponsive for about 5 seconds.
This is not needed in the common case LRO is enabled, as LRO
(TPA_ENABLE_FLAG) has precedence over GRO (GRO_ENABLE_FLAG)
Tested:
Verified that "ethtool -K eth0 gro {on|off}" doesn't blackout
the NIC anymore
