Use npc_install_flow mailbox API for installing the default promisc
and broadcast match entries. Earlier these entries were installed
using low level npc_config_mcam_entry API, which does not store these
rules and is not available when the rules are dumped using debugfs.
Added chan_mask field to npc_install_flow_req to calculate channel
mask when channel count is greater than 1 and configure the channel
mask in entry kw_mask.

This patch adds support for multi channel NIX promisc entry. Packets sent
on all those channels by the host should be received by the interface to
which those channels belong. Channel count, if greater than 1, should be
power of 2 as only one promisc entry is available for the interface. Key
mask is modified such that incoming packets from channel base to channel
count are directed to the same pci function.

This patch refactors npc_install_flow function to install AF
installed default MCAM entries similar to other MCAM entries
installed by PF/VF. As a result the code would be more readable
and easy to maintain. Modified npc_verify_entry and npc_verify_channel
to properly check MCAM rules installed by AF.

mlxsw: Allow 802.1d and .1ad VxLAN bridges to coexist on Spectrum>=2
Ido Schimmel says:
====================
This patchset allows user space to simultaneously configure both 802.1d
and 802.1ad VxLAN bridges on Spectrum-2 and later ASICs. 802.1ad VxLAN
bridges are still forbidden on Spectrum-1.
The reason for the current limitation is that up until now the EtherType
that was pushed to decapsulated VxLAN packets was a property of the
tunnel port, of which there is only one. This meant that a 802.1ad VxLAN
bridge could not be configured if the tunnel port was already configured
to push a 802.1q tag.
This patchset improves the situation by making two changes. First,
decapsulated packets are marked as having their EtherType decided by the
egress port. Second, local ports member in the bridge (e.g., swp1) are
configured to set the correct egress EtherType.
Patchset overview:
Patch #1 adds a register required for the first change
Patches #2-#3 add the register required for the second change and a
corresponding API
Patch #4 prepares the driver for the split in behavior between
Spectrum-1 and later ASICs
Patch #5 performs the two above mentioned changes to allow the driver to
support simultaneous 802.1ad and 802.1d VxLAN bridges on Spectrum-2 and
later ASICs
Patch #6 adds a selftest
Patch #7 removes a selftest that verified the limitation that was lifted
by this patchset

Currently only one EtherType can be configured for pushing in tunnels
because EtherType is configured using SPVID.et_vlan for tunnel port.
This behavior is forbidden by comparing mlxsw_sp_nve_config struct for
each new tunnel, the struct contains 'ethertype' field which means that
only one EtherType is legal at any given time. Remove 'ethertype' field to
allow creating VxLAN devices with different bridges.
To allow using several types of VxLAN bridges at the same time, the
EtherType should be determined at the egress port. This behavior is
achieved by setting SPVID to decide which EtherType to push at egress and
for each local_port which is member in 802.1ad bridge, set SPEVET.et_vlan
to ether_type1 (i.e., 0x88A8).
Use switchdev_ops->init() to set different mlxsw_sp_bridge_ops for
different ASICs in order to be able to split the behavior when port joins /
leaves an 802.1ad bridge in different ASICs.

A subsequent patch will need to implement different set of operations
when a port joins / leaves an 802.1ad bridge, based on the ASIC type.
Prepare for this change by allowing to initialize the bridge module
based on the ASIC type via 'struct mlxsw_sp_switchdev_ops'.

A subsequent patch will cause decapsulated packets to have their EtherType
determined by the egress port. Add mlxsw_sp_port_egress_ethtype_set() which
will be called when a port joins an 802.1ad bridge, so that it will set an
802.1ad EtherType on decapsulated packets transmitted through it, instead
of the default 802.1q EtherType.

SPEVET configures which EtherType to push at egress for packets incoming
through a local port for which 'SPVID.egr_et_set' is set.
The next patches will use SPEVET to configure EtherType 0x88A8 and
0x8100 for local ports member in 802.1ad and 802.1q bridges,
respectively. This allows using dual VxLAN bridges (802.1d and 802.1ad at
the same time).

SPVID.egr_et_set=1 means that when VLAN is pushed at ingress (for untagged
packets or for QinQ push mode) then the EtherType is decided at the egress
port.
The next patches will use this field for VxLAN devices (tunnel port) in
order to allow using dual VxLAN bridges (802.1d and 802.1ad at the same
time).

tipc: cleanups and simplifications
We do a number of cleanups and simplifications, especially regarding
call signatures in the binding table. This makes the code easier to
understand and serves as preparation for upcoming functional additions.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The function tipc_report_overlap() is called from the binding table
with numerous parameters taken from an instance of struct publication.
A closer look reveals that it always is safe to send along a pointer
to the instance itself, and hence reduce the call signature. We do
that in this commit.
