0eb62b93cb net/mlx4: Add structures to keep VF Ethernet ports information
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.

6ce71acdea net/mlx4: Add reference counting to MAC registeration
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.

37fe066098 net: fix address check in rtnl_fdb_del
Commit 6681712d67
	vxlan: generalize forwarding tables

relaxed the address checks in rtnl_fdb_del() to use is_zero_ether_addr().
This allows users to add multicast addresses using the fdb API.  However,
the check in rtnl_fdb_del() still uses a more strict
is_valid_ether_addr() which rejects multicast addresses.  Thus it
is possible to add an fdb that can not be later removed.
Relax the check in rtnl_fdb_del() as well.

a11fbba9a7 net/cpsw: fix irq_disable() with threaded interrupts
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.

d1bd9acfa3 net/cpsw: make sure modules remove does not leak any ressources
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.

is:

b4727e69b8 net/cpsw: redo rx skb allocation in rx path
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.

fd51cf1994 net/cpsw: don't rely only on netif_running() to check which device is active
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.

aacebbf802 net/cpsw: don't continue if we miss to allocate rx skbs
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.

This information needs to be calculated by bnx2x and propagated into bnx2fc

OVS locking was recently changed to have private OVS lock which
simplified overall locking.  Therefore there is no need to have
another global genl lock to protect OVS data structures.  Following
patch uses of parallel_ops genl family for OVS.  This also allows
more granual OVS locking using ovs_mutex for protecting OVS data
structures, which gives more concurrencey.  E.g multiple genl
operations OVS_PACKET_CMD_EXECUTE can run in parallel, etc.

ee80fbf301 packet: account statistics only in tpacket_stats_u
Currently, packet_sock has a struct tpacket_stats stats member for
TPACKET_V1 and TPACKET_V2 statistic accounting, and with TPACKET_V3
``union tpacket_stats_u stats_u'' was introduced, where however only
statistics for TPACKET_V3 are held, and when copied to user space,
TPACKET_V3 does some hackery and access also tpacket_stats' stats,
although everything could have been done within the union itself.

Unify accounting within the tpacket_stats_u union so that we can
remove 8 bytes from packet_sock that are there unnecessary. Note that
even if we switch to TPACKET_V3 and would use non mmap(2)ed option,
this still works due to the union with same types + offsets, that are
exposed to the user space.

b9c32fb271 packet: if hw/sw ts enabled in rx/tx ring, report which ts we got
Currently, there is no way to find out which timestamp is reported in
tpacket{,2,3}_hdr's tp_sec, tp_{n,u}sec members. It can be one of
SOF_TIMESTAMPING_SYS_HARDWARE, SOF_TIMESTAMPING_RAW_HARDWARE,
SOF_TIMESTAMPING_SOFTWARE, or a fallback variant late call from the
PF_PACKET code in software.

Therefore, report in the tp_status member of the ring buffer which
timestamp has been reported for RX and TX path. This should not break
anything for the following reasons: i) in RX ring path, the user needs
to test for tp_status & TP_STATUS_USER, and later for other flags as
well such as TP_STATUS_VLAN_VALID et al, so adding other flags will
do no harm; ii) in TX ring path, time stamps with PACKET_TIMESTAMP
socketoption are not available resp. had no effect except that the
application setting this is buggy. Next to TP_STATUS_AVAILABLE, the
user also should check for other flags such as TP_STATUS_WRONG_FORMAT
to reclaim frames to the application. Thus, in case TX ts are turned
off (default case), nothing happens to the application logic, and in
case we want to use this new feature, we now can also check which of
the ts source is reported in the status field as provided in the docs.

====================
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

This patch removes id defines from the hardware files that will not be

6f3dc319ec igb: Retain HW VLAN filtering while in promiscuous + VT mode
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.

c0ba477807 igb: display a warning message when SmartSpeed works
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.

b09186d29e igb: Use pci_vfs_assigned instead of igb_vfs_are_assigned

5a8eb24292 pci: Add SRIOV helper function to determine if VFs are assigned to guest
This function is meant to add a helper function that will determine if a PF
has any VFs that are currently assigned to a guest.  We currently have been
implementing this function per driver, and going forward I would like to avoid
that by making this function generic and using this helper.

v2: Removed extern from declaration of pci_vfs_assigned in pci.h and return
    0 if SR-IOV is disabled with is inline with other PCI SRIOV functions.

345be204dc ixgbe: add SFP+ LX module support
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.

6b92b0ba75 ixgbe: rename wol_supported to more fitting wol_enabled
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
variable to avoid confusion.
