When VFs are created, the MAC address defaults to all zeros, indicating
to the VF driver that it should use a random MAC address. However, the
PF driver was incorrectly adding this zero MAC to the filter table,
along with the VF's randomly generated MAC address.

Check for a good address before adding the default filter. While we're
at it, make the error message a bit more useful.

The virtual channel interface was using incorrect semantics to remove

MAC addresses from all VLANs, and call this function when the VF

10GbE Intel Wired LAN Driver Updates 2015-12-12

This series contains updates to ixgbe only.

Alex Duyck provides almost off of the changes in this series.  First, add a
check to make sure mac_table was actually allocated and is not NULL to
ensure we do not get a NULL pointer dereference further down the line.
Fixed SR-IOV VLAN pool configuration since the code for checking the PF bit
in ixgbe_set_vf_vlan_msg() was using the wrong offset.  Cleanup/simplify
the logic for setting the VFTA register by removing the number of
conditional checks needed.  Fixed a number of issues within the VLVF and
VLFB configuration by simplifying the code.  Added support for bypassing
the VLVF entry creation when the PF is adding a new VLAN.  Reduced the
complexity of the search function used for finding a VLVF entry associated
with a given VLAN ID.  Added support for VLAN promiscuous with SR-IOV
enabled by setting all the bits in the VFTA and all of the VLVF bits
associated with teh pool belonging to the PF, in addition to cleaning up
those same bits in the event of promiscuous mode being disabled.  Fixed
and issue where we ran the risk of leaking an address into pool 0 which
really belongs to VF 0 when SR-IOV is enabled.

Emil fixes an issue with some X550 devices which can connect at 2.5Gbps,
but only with certain link partners during fail-over, so to avoid
confusion, we do not report it as supported.

Add support for renaming and hard links to the fs. Most of this can be
implemented by using simple library operations under the same constraints
that we don't use a reserved name like elsewhere. Linking can be useful
to share/manage things like maps across subsystem users. It works within
the file system boundary, but is not allowed for directories.

Symbolic links are explicitly not implemented here, as it can be better
done already by doing bind mounts inside bpf fs to set up shared directories
f.e. useful when using volumes in docker containers that map a private
working directory into /sys/fs/bpf/ which contains itself a bind mounted
path from the host's /sys/fs/bpf/ mount that is shared among multiple
containers. For single maps instead of whole directory, hard links can
be easily used to do the same.

This patch adds support for VLAN promiscuous with SR-IOV enabled.

The code prior to this patch was only adding the PF to VLANs that the VF
had added.  As such enabling promiscuous mode would actually not add any
additional VLAN filters so visibility was limited.  This lead to a number
of issues as the bridge and OVS would expect us to accept all VLAN tagged
packets when promiscuous mode was enabled, and instead we would filter out
most if not all depending on the configuration of the PF.

With this patch what we do is set all the bits in the VFTA and all of the
VLVF bits associated with the pool belonging to the PF.  By doing this the
PF is guaranteed to receive all VLAN tagged traffic associated with the RAR
filters assigned to the PF.  In addition we will clean up those same bits
in the event of promiscuous mode being disabled.

This patch addresses several issues within the VLVF and VLVFB
configuration

First was the fact that code was overly complicated with multiple
conditional paths depending on if we adding or removing and which bit we
were going to add or remove.  Instead of messing with all that I have
simplified it by using (vid / 32) and (1 - vid / 32) to identify our
register and the other vlvfb register.

Second was the fact that we were likely leaking a few packets into the PF
in cases where we were deleting an entry and the VFTA filter for that entry
as the ordering was such that we deleted the pool and then the VLAN filter
instead of the other way around.  I have updated that by adding a check for
no bits being set and if that occurs we clear things up in the proper
order.

====================
mlx5 improved flow steering management

First two patches fixes some minor issues in recently
introduced SRIOV code.

The other seven patches modifies the driver's code that
manages flow steering rules with Connectx-4 devices.

Basic introduction:

The flow steering device specification model is composed of the following entities:

Destination (either a TIR/Flow table/vport), where TIR is RSS end-point, vport
is the VF eSwitch port in SRIOV.

Flow table entry (FTE) - the values used by the flow specification
Flow table group (FG) - the masks used by the flow specification
Flow table (FT) - groups several FGs and can serve as destination

The flow steering software entities:

In addition to the device objects, the software have two more objects:

Priorities - group several FTs. Handles order of packet matching.

Namespaces - group several priorities. Namespace are used in order to
isolate different usages of steering (for example, add two separate
namespaces, one for the NIC driver and one for E-Switch FDB).

The base data structure for the flow steering management is a tree and
all the flow steering objects such as (Namespace/Flow table/Flow Group/FTE/etc.)
are represented as a node in the tree, e.g.:
Priority-0 -> FT1 -> FG -> FTE -> TIR (destination)
Priority-1 -> FT2 -> FG->  FTE -> TIR (destination)

Matching begins in FT1 flow rules and if there is a miss on all the FTEs
then matching continues on the FTEs in FT2.

The new implementation solves/improves the following
issues in the current code:

1) The new impl. supports multiple destinations, the search for existing rule with
   the same matching value is performed by the flow steering management.
   In the current impl. the E-switch FDB management code needs to search
   for existing rules before calling to the add rule function.

2) The new impl. manages the flow table level, in the current implementation the
   consumer states the flow table level when new flow table is created without
   any knowledge about the levels of other flow tables.

3) In the current impl. the consumer can't create or destroy flow
   groups dynamically, the flow groups are passed as argument to the create
   flow table API. The new impl. exposes API for create/destroy flow group.

The series is built as follows:

Patch #1 add flow steering API firmware commands.

Patch #2 add tree operation of the flow steering tree: add/remove node,
initialize node and take reference count on a node.

Patch #3 add essential algorithms for managing the flow steering.

Patch #4 Initialize the flow steering tree, flow steering initialization is based
on static tree which illustrates the flow steering tree when the driver is loaded.

Patch #5 is the main patch of the series. It introduce the flow steering API.

Patch #6 Expose the new flow steering API and remove the old one.
The Ethernet flow steering follows the existing implementation,
but uses the new steering API.

Patch #7 Rename en_flow_table.c to en_fs.c in order to be aligned with
the new flow steering files.

the new steering API. The old flow steering implementation is removed.

2. Move the E-switch FDB management to use the new API.

3. When driver is loaded call to mlx5_init_fs which initialize
the flow steering tree structure, open namespaces for NIC receive
and for E-switch FDB.

4. Call to mlx5_cleanup_fs when the driver is unloaded.

Flow steering initialization is based on static tree which
illustrates the flow steering tree when the driver is loaded. The
initialization considers the max supported flow table level of the device,
a minimum of 2 kernel flow tables(vlan and mac) are required to have
kernel flow table functionality.

The tree structures when the driver is loaded:

		root_namespace(receive nic)
			  |
		priority-0 (kernel priority)
			  |
		namespace(kernel namespace)
			  |
		priority-0 (flow tables priority)

In the following patches, When the EN driver will use the flow steering
API, it create two flow tables and their flow groups under
priority-0(flow tables priority).

type tree(e.g NIC receive, FDB, etc..)

mlx5_flow_group: define the mask of the flow specification.

fs_fte(flow steering flow table entry): defines the value of the
flow specification.

The following describes the relationships between the tree objects:
root_namespace --> priorities -->namespaces -->
priorities -->flow-tables --> flow-groups -->
flow-entries --> destinations

When we create new object(flow table/flow group/flow table entry), we
call to the FW command and then we add the related sw object to the tree.

When we destroy object, e.g. call to mlx5_destroy_flow_table, we use
the tree node destructor for destroying the FW object and remove the
node from the tree.

Introduce the flow steering mlx5_flow_namespace (Namespace)
and fs_prio (Flow Steering Priority) tree nodes.

Namespaces are used in order to isolate different usages or types
of steering (for example, downstream patches will add a different
namespaces for the NIC driver and for E-Switch FDB usages).

Flow Steering Priorities are objects that describes priorities
ranges between different flow objects under the same namespace.

Example, entries in priority i are matched before entries
in priority i+1.

This patch adds the following algorithms:

1) Calculate level:
Each flow table has level(the priority between the flow tables).
When we initialize the flow steering tree, we assign range of levels
to each priority, therefore the level for new flow table is
the location within the priority related to the range of the priority.

2) Match between match criteria. This function is used
for searching flow group when new flow rule is added.

3) Match between match values. This function is used
for searching flow table entry  when new flow rule is added.

4) Add essential macros for traversing on a node's children.
E.g. traversing on all the flow table of some priority

mvneta: Introduce RSS support and XPS configuration

this series is the first step add RSS support on mvneta.

It will allow associating an ethernet interface to a given CPU through
RSS by using "ethtool -X ethX weight". Indeed, currently I only enable
one entry in the RSS lookup table. Even if it is not really RSS, it
allows to get back the irq affinity feature we lost by using the
percpu interrupt.

The main change compared to the second version is the setup for the XPS
instead of using specific hack inside the driver in the forth
patch.

Th first patch make the default queue associate to each port and no
more a global variable.

The second patch really associates the RX queues with the CPUs instead
of masking the percpu interrupts for doing it. All the RX queues are
enabled and are statically associated with the CPUs by using a modulo
of the number of present CPUs. But at this stage only one RX queue
will receive the stream.

The third patch introduces a first level of RSS support through the
ethtool functions. As explained in the introduction there is only one
entry in the RSS lookup table which permits at the end to associate an
mvneta port to a CPU through the RX queues because the mapping is
static.
