40ba35e74f net: mvneta: add missing bit descriptions for interrupt masks and causes
Marvell has not published the chip's datasheet yet, so it's very hard
to find the relevant bits to manipulate to change the IRQ behaviour.
Fortunately, these bits are described in the proprietary LSP patch set
which is publicly available here :

    http://www.plugcomputer.org/downloads/mirabox/

So let's put them back in the driver in order to reduce the burden of
current and future maintenance.

Ben Hutchings attempted to propose a better fix consisting in using a
scheduled work for this, but while it fixed this panic, it caused other
random freezes and panics proving that the reset sequence in the driver
is unreliable and that additional fixes should be investigated.

When sending multiple streams over a link limited to 100 Mbps, Tx timeouts
happen from time to time, and the driver correctly recovers only when the
function is disabled.

74c41b048d net: mvneta: use per_cpu stats to fix an SMP lock up
Stats writers are mvneta_rx() and mvneta_tx(). They don't lock anything
when they update the stats, and as a result, it randomly happens that
the stats freeze on SMP if two updates happen during stats retrieval.
This is very easily reproducible by starting two HTTP servers and binding
each of them to a different CPU, then consulting /proc/net/dev in loops
during transfers, the interface should immediately lock up. This issue
also randomly happens upon link state changes during transfers, because
the stats are collected in this situation, but it takes more attempts to
reproduce it.

The comments in netdevice.h suggest using per_cpu stats instead to get
rid of this issue.

This patch implements this. It merges both rx_stats and tx_stats into
a single "stats" member with a single syncp. Both mvneta_rx() and
mvneta_rx() now only update the a single CPU's counters.

In turn, mvneta_get_stats64() does the summing by iterating over all CPUs
to get their respective stats.

With this change, stats are still correct and no more lockup is encountered.

Note that this bug was present since the first import of the mvneta
driver.  It might make sense to backport it to some stable trees. If
so, it depends on "d33dc73 net: mvneta: increase the 64-bit rx/tx stats
out of the hot path".

dc4277dd41 net: mvneta: increase the 64-bit rx/tx stats out of the hot path
Better count packets and bytes in the stack and on 32 bit then
accumulate them at the end for once. This saves two memory writes
and two memory barriers per packet. The incoming packet rate was
increased by 4.7% on the Openblocks AX3 thanks to this.

dbf231af81 ixgbe: Clear head write-back registers on VF reset
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.

d9aee591b0 bnx2x: Don't release PCI bars on shutdown
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.

incorrectly set the adapter->cmd_privileges value for VFs (in a

The i40e Physical Function (PF) driver will allow the
 Virtual Function (VF) driver to configure its own VLAN filters if no port
 VLAN filter has been configured.  This leads to the possibility of the
 administrator setting a port VLAN filter for the VF after the VF has already
 configured its own VLAN filters.  This leads to a conflict that can only be
 resolved by reloading the VF driver.  When the conflicting administrative
 command is detected in setting the port VLAN then log a message indicating to
 the system administrator that he must now reload the VF driver for the new
 port VLAN settings to take effect.

49bde31966 ixgbe: Make ethtool register test use accessors
Make the ethtool register test use the normal register accessor
functions. Also eliminate macros used for calling register test
functions to make error exits clearer. Use boolean values for
boolean returns instead of 0 and 1.

84227bcd9c ixgbe: Use static inlines instead of macros
Kernel coding standard prefers static inline functions instead
of macros, so use them for register accessors. This is to prepare
for adding LER, Live Error Recovery, checks to those accessors.

Temporarily provide macros for calling the new static inline
accessors until all references are changed.

c3049c8f25 ixbge: Protect ixgbe_down with __IXGBE_DOWN bit
The ixgbe_down function can now prevent multiple executions by
doing test_and_set_bit on __IXGBE_DOWN. This did not work before
introduction of the __IXGBE_REMOVING bit, because of overloading
of __IXGBE_DOWN. Also add smp_mb__before_clear_bit call before
clearing the __IXGBE_DOWN bit.

09f40aeddd ixgbe: Indicate removal state explicitly
Add a bit, __IXGBE_REMOVING, to indicate that the module is being
removed. The __IXGBE_DOWN bit had been overloaded for this purpose,
but that leads to trouble. A few places now check both __IXGBE_DOWN
and __IXGBE_REMOVE. Notably, setting either bit will prevent service
task execution.

hardware-specific stats aren't matched to the right net_device_stats
field. Also fix the collision field and include errors in the total
number of RX/TX packets. Add a rx_dropped field and use it where
netdev->stats was modified directly out of the stats update function.

This will allow VFs to communicate with their parent PFs.
