Add support to ndo_set_vf_vlan in the driver. Once this call is used the vport
is considered to be in VST mode. In this mode, the PPF driver configures
Ethernet QPs created by this VF to use this vlan id and priority. Currently
RoCE isn't supported on that mode.
The special values of VID=4095 or VID=0,UP=0 are considered as VGT.

This patch add struct mlx4_vport_state where all the parameters related
to management of VFs port (virtual ports of the NIC eswitch) are kept.
The driver keeps an administrative and operational copy of the settings.
The current administrative copy becomes operational on the event of probing
a VF either on a VM or on the host.

Add reference counting to the driver MAC registeration code. This would
be needed for cases where a mac is registered from more than once, e.g
when both the host and the VM driver register the same mac, the host
for mac spoof protection purposes and the VM for its regular needs.

During high throughput it is likely that we receive both: an RX and TX
interrupt. The normal behaviour is that once we enter the ISR the
interrupts are disabled in the IRQ chip and so the ISR is invoked only
once and the interrupt line is disabled once. It will be re-enabled
after napi completes.
With threaded interrupts on the other hand the interrupt the interrupt
is disabled immediately and the ISR is marked for "later". By having TX
and RX interrupt marked pending we invoke them both and disable the
interrupt line twice. The napi callback is still executed once and so
after it completes we remain with interrupts disabled.
The initial patch simply removed the cpsw_{enable|disable}_irq() calls
and it worked well on my AM335X ES1.0 (beagle bone). On ES2.0 (beagle
bone black) it caused an never ending interrupt (even after the mask via
cpsw_intr_disable()) according to Mugunthan V N. Since I don't have the
ES2.0 and no idea what is going on this patch tracks the state of the
irq_disable() call and execute it only when not yet done.
The book keeping is done on the first struct since with dual_emac we can
have two of those and only one interrupt line.

This driver does not clean up properly after leaving. Here is a list:
- Use unregister_netdev(). free_netdev() is good but not enough
- Use the above also on the other ndev in case of dual mac
- Free data.slave_data. The name of the strucre makes it look like
it is platform_data but it is not. It is just a trick!
- Free all irqs. Again: freeing one irq is good start, but freeing all
of them is better.
With this rmmod & modprobe of cpsw seems to work. The remaining issue
is:

In case that we run into OOM during the allocation of the new rx-skb we
don't get one and we have one skb less than we used to have. If this
continues to happen then we end up with no rx-skbs at all.
This patch changes the following:
- if we fail to allocate the new skb, then we treat the currently
completed skb as the new one and so drop the currently received data.
- instead of testing multiple times if the device is gone we rely one
the status field which is set to -ENOSYS in case the channel is going
down and incomplete requests are purged.
cpdma_chan_stop() removes most of the packages with -ENOSYS. The
currently active packet which is removed has the "tear down" bit set.
So if that bit is set, we send ENOSYS as well otherwise we pass the
status bits which are required to figure out which of the two possible
just finished.

netif_running() reports false before the ->ndo_stop() callback is
called. That means if one executes "ifconfig down" and the system
receives an interrupt before the interrupt source has been disabled we
hang for always for two reasons:
- we never disable the interrupt source because devices claim to be
already inactive and don't feel responsible.
- since the ISR always reports IRQ_HANDLED the line is never deactivated
because it looks like the ISR feels responsible.
This patch changes the logic in the ISR a little:
- If none of the status registers reports an active source (RX or TX,
misc is ignored because it is not actived) we leave with IRQ_NONE.
- the interrupt is deactivated
- The first active network device is taken and napi is scheduled. If
none are active (a small race window between ndo_down() and the
interrupt the) then we leave and should not come back because the
source is off.
There is no need to schedule the second NAPI because both share the
same dma queue.

if during "ifconfig up" we run out of mem we continue regardless how
many skbs we got. In worst case we have zero RX skbs and can't ever
receive further packets since the RX skbs are never reallocated. If
cpdma_chan_submit() fails we even leak the skb.
This patch changes the behavior here:
If we fail to allocate an skb during bring up we don't continue and
report that error. Same goes for errors from cpdma_chan_submit().
While here I changed to __netdev_alloc_skb_ip_align() so GFP_KERNEL can
be used.

__cpdma_chan_process() holds the lock with interrupts off (and its
caller as well), same goes for cpdma_ctlr_start(). With interrupts off,
jiffies will not make any progress and if the wait condition never gets
true we wait for ever.
Tgis patch adds a a simple udelay and counting down attempt.

The firmware supports a maximum of 4K FCoE exchanges. In 4-port devices,
or when working in multi-function mode, this resource needs to be distributed
between the various possible FCoE functions.
This information needs to be calculated by bnx2x and propagated into bnx2fc
via cnic. bnx2fc can then use this value to calculate corresponding xid
resources instead of using global constants.

Jeff Kirsher says:
====================
This series contains updates to ixgbe, igb and pci.
The ixgbe changes contains a fix to a possible divide by zero by bailing
out of the ixgbe_update_itr() function if the last interrupt timeslice is
zero. In addition, support is added for the new OCP x520 adapter as well
as LX support for 82599 devices. Jacob provides a patch to change
variable wol_supported to wol_enabled to better reflect what the code
is actually doing (i.e. checking if WoL is enabled).
Alex adds SRIOV helper function to pci that will determine if a PF
has any VFs that are currently assigned to a guest.
The remaining 8 patches are against igb and contain the following changes:
* implement SERDES loopback configuration for i210 devices by unsetting
sigdetect bit, so as to fix Ethtool loopback test failure
* add support for the SMBI semaphore for I210/I211 devices
* implement the new generic pci_vfs_assigned helper function (Alex's PCI
helper function)
* display warning when link speed is downgraded due to Smartspeed
* ensure that VLAN hardware filtering remains enabled when the device is
in promiscuous mode and VT mode simultaneously
* cleanup dead code in igb
* bump the driver version
v2: updated the PCI patch to add SRIOV helper function to remove extern
from the declaration of pci_vfs_assigned in pci.h and return 0 if
SR-IOV is disabled which is inline with other PCI SR-IOV functions

When using the new bridge FDB interface to allow SR-IOV virtual function
network devices to communicate with SW bridged network devices the
physical function is placed into promiscuous mode and hardware VLAN
filtering is disabled. This defeats the ability to use VLAN tagging
to isolate user networks. When the device is in promiscuous mode and
VT mode simultaneously ensure that VLAN hardware filtering remains
enabled.

Current igb driver doesn't tell nothing when Link Speed is downgraded due to
SmartSpeed. As a result, users suspect that there is something wrong with
NIC. If the cause of it is SmartSpeed, there is no means to replace NIC. This
patch make igb notify users that SmartSpeed worked.

This patch adds LX support to 82599 devices. This is an alternate patch to
the one suggested by Stefan Behte <s.behte@babiel.com>
In addition this patch includes some cleanups such as:
- removed parenthesis around "x == y ||" lines inside an if statement for
consistency.
- grouped the sx/lx sfp types along with srlr in ixgbe_get_settings() since
they all have the same supported, advertised and port values.

The variable wol_supported really is just checking whether it is enabled, rather
than whether it is supported. If it is enabled it will be supported, but this
does not necessarily hold true the other way around. This patch renames the

As part of PCIe Advanced Error Reporting flow, if a fatal PCI error occurs,
the AER driver will cause bnx2x's PCI-core to reset. The driver's PCI error
handlers will in turn restore the PCI configuration space values by calling
`pci_restore_state'.
However, as bnx2x does not save the PCI configuration after restoration,
An additional fatal PCI error will leave the function in an unstable state
until reboot, as the registers in the PCI configuration space will contain
reset values.

There exists an `allocation race' between the CNIC and bnx2x drivers,
in which both drivers allocate the same t2 memory while disregarding a possible
previous allocation.
Additionally, due to the current order of memory releases, some of the
ILT memory in the driver is not released correctly when unloading the driver.

This patch introduces a more robust error handling flow in case of incorrect
behaviour by the FW when passing on GRO aggregations.
Although this should never happen (i.e., this is merely a theoretical fix),
if the bnx2x driver was to receive a GRO from FW with protocol other than
IPv4/IPv6, the driver would falsely claim to have performed partial
checksum and set various incorrect fields in the skb header.
Current behaviour of the bnx2x driver (i.e., print an error) is insufficient.
This patch remedies this by simply preventing the false claims.
