Instead of trapping certain packets to the CPU and then relying on it to
flood them we can instead make the device mirror them.
The following packet types are mirrored:
* DHCP: Broadcast packets that should be flooded by the device, but also
trapped in case CPU is running the DHCP server.
* IGMP query: Multicast packets that need to be forwarded to other
bridge ports, but also trapped so that receiving netdev will be marked
as a router port by the bridge driver.
* ARP request: Broadcast packets that should be forwarded to other
bridge ports, but also trapped in case requested IP is of the local
machine.
* ARP response: Unicast packets that should be forwarded by the bridge
but also trapped in case response is directed at us.
Set the trap action of such packets to mirror and mark them using
'offload_fwd_mark' to prevent the bridge driver from forwarding them
itself.
Note that OSPF packets are also marked despite their action being trap.
The reason for this is that the device traps such packets in the
pipeline after they were already flooded.

switchdev_port_fwd_mark_set() is used to set the 'offload_fwd_mark' of
port netdevs so that packets being flooded by the device won't be
flooded twice.
It works by assigning a unique identifier (the ifindex of the first
bridge port) to bridge ports sharing the same parent ID. This prevents
packets from being flooded twice by the same switch, but will flood
packets through bridge ports belonging to a different switch.
This method is problematic when stacked devices are taken into account,
such as VLANs. In such cases, a physical port netdev can have upper
devices being members in two different bridges, thus requiring two
different 'offload_fwd_mark's to be configured on the port netdev, which
is impossible.
The main problem is that packet and netdev marking is performed at the
physical netdev level, whereas flooding occurs between bridge ports,
which are not necessarily port netdevs.
Instead, packet and netdev marking should really be done in the bridge
driver with the switch driver only telling it which packets it already
forwarded. The bridge driver will mark such packets using the mark
assigned to the ingress bridge port and will prevent the packet from
being forwarded through any bridge port sharing the same mark (i.e.
having the same parent ID).
Remove the current switchdev 'offload_fwd_mark' implementation and
instead implement the proposed method. In addition, make rocker - the
sole user of the mark - use the proposed method.

When team is in bridge and LACP is utilized, LACPDU packets are pushed
to userspace using raw socket and there they are processed. However,
since 8626c56c8279b, LACPDU skbs are dropped by bridge rx_handler so
they never reach packet handlers in rx path. Fix this by explicity treat
LACPDUs to be pushed to exact delivery in team rx_handler.

function
The bootloader (U-boot) sometimes uses this timer for various delays.
It uses it as a ongoing counter, and does comparisons on the current
counter value. The timer counter is never stopped.
In some cases when the user interacts with the bootloader, or lets
it idle for some time before loading Linux, the timer may expire,
and an interrupt will be pending. This results in an unexpected
interrupt when the timer interrupt is enabled by the kernel, at
which point the event_handler isn't set yet. This results in a NULL
pointer dereference exception, panic, and no way to reboot.
Clear any pending interrupts after we stop the timer in the probe
function to avoid this.

When cp_rx_poll does not get enough packet, it will check the rx
interrupt status again. If so, it will jumpt to rx_status_loop again.
But the goto jump resets the rx variable as zero too.
As a result, it causes one possible deadloop. Assume this case,
rx_status_loop only gets the packet count which is less than budget,
and (cpr16(IntrStatus) & cp_rx_intr_mask) condition is always true.
It causes the deadloop happens and system is blocked.

We kept shadow copies of which interrupt sources we have enabled and
disabled, but due to an order bug in how intrl2_mask_clear was defined,
we could run into the following scenario:
CPU0 CPU1
intrl2_1_mask_clear(..)
sets INTRL2_CPU_MASK_CLEAR
bcm_sf2_switch_1_isr
read INTRL2_CPU_STATUS and masks with stale
irq1_mask value
updates irq1_mask value
Which would make us loop again and again trying to process and interrupt
we are not clearing since our copy of whether it was enabled before
still indicates it was not. Fix this by updating the shadow copy first,
and then unasking at the HW level.

For reasons that entirely elude me fb.h exposes all the structures,
even when it is not enabled. Except for special stuff like fb_defio.
Which means all the drivers which haven't yet switched over to the
defio support in the helpers and still roll their own, will fail
to compile when fbdev emulation is disabled. Protect just those
bits, as a gnarly reminder that conversion to the core defio helpers
would be good.

Now that the dsa_switch_driver structure contains only function pointers
as it is supposed to, rename it to the more appropriate dsa_switch_ops,
uniformly to any other operations structure in the kernel.
No functional changes here, basically just the result of something like:
s/dsa_switch_driver *drv/dsa_switch_ops *ops/g
However keep the {un,}register_switch_driver functions and their
dsa_switch_drivers list as is, since they represent the -- likely to be
deprecated soon -- legacy DSA registration framework.
In the meantime, also fix the following checks from checkpatch.pl to

If port_guid is set with the default subnet_prefix, then we get a change

result, attempts to create a target device that uses the new
subnet_prefix in the wwn will fail to find a match and be rejected by
the ib_srpt driver. This makes it impossible to configure a port if it
was initialized with a default subnet_prefix and later changed to any

When ndo_set_rx_mode() is called for bnx2x, as part of process of
configuring the new MAC address filters [both unicast & multicast]
driver begins by flushing the existing configuration and then iterating
over the network device's list of addresses and configures those instead.
This has the side-effect of creating a short gap where traffic wouldn't
be properly classified, as no filters are configured in HW.
While for unicasts this is rather insignificant [as unicast MACs don't
frequently change while interface is actually running],
for multicast traffic it does pose an issue as there are multicast-based
networks where new multicast groups would constantly be removed and
added.
This patch tries to remedy this [at least for the newer adapters] -
Instead of flushing & reconfiguring all existing multicast filters,
the driver would instead create the approximate hash match that would
result from the required filters. It would then compare it against the
currently configured approximate hash match, and only add and remove the
delta between those.

Before commit 99724c18fc66 ("mlxsw: spectrum: Introduce support for

these vPorts were used for slow path traffic we had to disable learning
for them, as it doesn't make sense to have it enabled.
This is no longer the case and now vPorts are either used for router
interfaces (for which learning is disabled by the firmware) or bridge
ports (for which learning is explicitly enabled by the driver).
Therefore, we can remove the learning configuration upon vPort creation.

Up until now we simply stored the learning configuration of a bridge
port in the driver and decided whether to learn a new FDB record based
on this value.
However, this is sub-optimal in cases where learning is disabled on the
bridge port, as the device repeatedly generates learning notifications
for the same record.
Instead, offload the learning configuration to the device, thereby
preventing it from generating notifications when learning is disabled.

We are going to prevent the device from generating learning
notifications for a port that was configured with learning disabled.
Since learning configuration is done per {Port, VID} we need to apply
the port's learning configuration for any VID that is added to the
bridge port's VLAN filter list.
When a VID is added to the VLAN filter list of a VLAN-aware bridge port,
configure the {Port, VID} learning status according to the port's
configuration. When the VID is removed, disable learning for the {Port,
VID}.

registering netdevice") removed __mlxsw_sp_port_vlans_del() from the
init sequence of the driver, which forced it to be non-symmetric with
regards to __mlxsw_sp_port_vlans_add().
Make both functions symmetric as the constraint no longer exists.

Up until now a learning session ended whenever the number of queried
records was zero. This turned out to be problematic in situations where
a large number of MACs (48K) had to be processed by the switch driver,
as RTNL mutex is held during the learning session.
Instead, limit the number of FDB records that can be processed in a
session to 64. This means that every time the device is queried for
learning notifications (currently, every 100ms), up to 64 records will
be processed by the switch driver.

Make the function mlxsw_router_neigh_construct search the rif according
to the neighbour dev other than the dev that was passed to the ndo, thus
allowing creating neigbhours upon stacked devices.

In case we have a layer 3 interface on top of a bridge (VLAN / FID RIF),
then we should flood the following packet types to the router:
* Broadcast: If DIP is the broadcast address of the interface, then we
need to be able to get it to CPU by trapping it following route lookup.
* Reserved IP multicast (224.0.0.X): Some control packets (e.g. OSPF)
use this range and are trapped in the router block.

Mellanox mlx5 core driver updates 2016-08-24
This series contains some low level and API updates for mlx5 core
driver interface and mlx5_ifc.h, plus mlx5 LAG core driver support,
to be shared as base code for net-next and rdma mlx5 4.9 submissions.
From Alex and Artemy, Update mlx5_ifc for modify RQ and XRC bits.
From Noa, Expose mlx5 link modes so they can be used in RDMA tree for rdma tools.
From Aviv, LAG support needed for RDMA.
- Add needed hardware structures, layouts and interface
- mlx5 core driver LAG implementation
- Introduce mlx5 core driver LAG API for mlx5_ib
From Maor, add two low level patches for mlx5 hardware sniffer QP
infrastructure bits and capabilities, plus added the namespace for sniffer
steering tables. Needed for RDMA subtree.
