unaligned reads making zero copy a performance win for much smaller
messages

- BPF type format information for kernel modules and related tracing
enhancements

- mt7915: dual band concurrent (DBDC) support

- net: ipa: add basic support for IPA v4.5

Refactor:

- a few pieces of in_interrupt() cleanup work from Sebastian Andrzej
Siewior

- phy: add support for shared interrupts; get rid of multiple driver
APIs and have the drivers write a full IRQ handler, slight growth
of driver code should be compensated by the simpler API which also
allows shared IRQs

- add common code for handling netdev per-cpu counters

- move TX packet re-allocation from Ethernet switch tag drivers to a
central place

- improve efficiency and rename nla_strlcpy

- number of W=1 warning cleanups as we now catch those in a patchwork
build bot

Old code removal:

- wan: delete the DLCI / SDLA drivers

- wimax: move to staging

- wifi: remove old WDS wifi bridging support"

Merge branch 'net-bridge-cfm-add-support-for-connectivity-fault-management-cfm'

Henrik Bjoernlund says:

====================
net: bridge: cfm: Add support for Connectivity Fault Management(CFM)

Connectivity Fault Management (CFM) is defined in 802.1Q
section 12.14.

Connectivity Fault Management (CFM) comprises capabilities for
detecting, verifying, and isolating connectivity failures in Virtual
Bridged Networks. These capabilities can be used in networks
operated by multiple independent organizations, each with restricted
management access to each other’s equipment.

CFM functions are partitioned as follows:
— Path discovery
— Fault detection
— Fault verification and isolation
— Fault notification
— Fault recovery

The primary CFM protocol shims are called Maintenance Points (MPs).
A MP can be either a MEP or a MHF.
The MEP:
-It is the Maintenance association End Point
described in 802.1Q section 19.2.
-It is created on a specific level (1-7) and is assuring
that no CFM frames are passing through this MEP on lower levels.
-It initiates and terminates/validates CFM frames on its level.
-It can only exist on a port that is related to a bridge.
The MHF:
-It is the Maintenance Domain Intermediate Point
(MIP) Half Function (MHF) described in 802.1Q section 19.3.
-It is created on a specific level (1-7).
-It is extracting/injecting certain CFM frame on this level.
-It can only exist on a port that is related to a bridge.
-Currently not supported.

There are defined the following CFM protocol functions:
-Continuity Check
-Loopback. Currently not supported.
-Linktrace. Currently not supported.

This CFM component supports create/delete of MEP instances and
configuration of the different CFM protocols. Also status information
can be fetched and delivered through notification due to defect
status change.

The user interacts with CFM using the 'cfm' user space client
program, the client talks with the kernel using netlink.

Any notification emitted by CFM from the kernel can be monitored in
user space by starting 'cfm_server' program.

Currently this 'cfm' and 'cfm_server' programs are standalone placed
in a cfm repository https://github.com/microchip-ung/cfm but it is
considered to integrate this into 'iproute2'.

v1 -> v2
Added the CFM switchdev interface and also added utilization by
calling the interface from the kernel CFM implementation trying
to offload CFM functionality to HW. This offload (CFM driver) is
currently not implemented.

Corrections based on RCF comments:
-The single CFM kernel implementation Patch is broken up into
three patches.
-Changed the list of MEP instances from list_head to
hlist_head.
-Removed unnecessary RCU list traversing.
-Solved RCU unlocking problem.
-Removed unnecessary comments.
-Added ASSERT_RTNL() where required.
-Shaping up on error messages.
-Correction NETLINK br_fill_ifinfo() to be able to handle
'filter_mask' with multiple flags asserted.

v2 -> v3
-The switchdev definition and utilization has been removed as
there was no switchdev implementation.
-Some compiling issues are fixed as Reported-by:
kernel test robot <lkp@intel.com>.

v3 -> v4
-Fixed potential crash during hlist walk where elements are
removed.
-Giving all commits unique titles.
-NETLINK implementation split into three commits.
-Commit "bridge: cfm: Bridge port remove" is merged with
commit "bridge: cfm: Kernel space implementation of CFM. MEP
create/delete."

v4 -> v5
-Reordered members in struct net_bridge to bring member
frame_type_list to the first cache line.
-Helper functions nla_get_mac() and nla_get_maid() are removed.
-The NLA_POLICY_NESTED() macro is used to initialize the
br_cfm_policy array.
-Fixed reverse xmas tree.

v5 -> v6
-Fixed that the SKB buffer was not freed during error handling return.
-Removed unused struct definition.
-Changed bool to u8 bitfields for space save.
-Utilizing the NETLINK policy validation feature.

v6 -> v7
-Removed check of parameters in br_cfm_mep_config_set() and
br_cfm_cc_peer_mep_add() in first commit of MEP implementation
(Patch 4 out of 10)
