new file monitor_stats.c for the new API.
add arm_monitor_counter new command support.
add set_monitor_counter new command support.
The device can monitor specific counters and provide an event to notify
when these counters are changed.
The monitoring is done in best effort manner where the minimum
notification period is 200 ms, however when the device is loaded, the
notification might be delayed.
To configure the required counters to be monitored, the
SET_MONITOR_COUNTER command shall be used with a list of counters to be
monitored.
The device firmware can monitor up to HCA_CAP.max_num_of_monitor_counters.
The configuration is done based on counter type (such as ppcnt, q counter,
etc) and additional param according to the type of counter selected.
Upon monitor counter change, the device will generate
Monitor_Counter_Change event.
The device will not generate new events unless the driver re-arms the
monitoring functionality, using the ARM_MONITOR_COUNTER command.

Writing 64B CQEs to 128B cache lines results in a RMW operation. Padding
the CQEs to 128B if possible improves performance on 128B cache line
systems like PPC.
Testing on PPC showed up to a 24% improvement in small packet throughput
vs the default behavior, depending on the workload and system topology.

Currently a flow is associated with a single encap structure. The FW
extended destination features enables the driver to associate a flow
with multiple encap instances.
Change the encap id field from a flow scope to a per destination value
in the flow attributes struct. Use the encaps array to associate a flow
table entry with multiple encap entries.
Update the neigh logic to offload only if all encapsulations used in a
flow are connected, and un-offload upon the first one disconnected.
Note that the driver can now support up to two encap destinations.

A rule with the following actions is split to a two level FDB:
1. Forward to local mirror vport
2. Header rewrite
3. Forward to local vport
In the first level flow table, forward the packet to the local port and
forward the packet to the second level flow table for header rewrite and
local port forwarding. This configuration fails when mirroring to a
remote encapsulated destination because currently an FTE cannot support
encap and table destinations.
Use the extended destination capabilities to configure the first level
flow table with a multi-destination FTE to the uplink and second level
table and the second level flow table for the header rewrite and local
port forwarding.

Currently the FTE encap flag applies to all destinations.
To support mirroring encapsulated traffic to a local port the driver
split the two destinations to two flow table entries:
Table#0: - FWD to the local vport
- Goto table#1
Table#1: - Encap and FWD to wire
The firmware extended destination capabilities enable the driver to set
an encapsulation flag per destination.
Remove the split logic and use the extended destination mechanism
instead.
Note that split technique is still required for pedit and VLAN push
scenarios.

pull-request: bpf-next 2018-12-11
The following pull-request contains BPF updates for your *net-next* tree.
It has three minor merge conflicts, resolutions:
1) tools/testing/selftests/bpf/test_verifier.c
Take first chunk with alignment_prevented_execution.
2) net/core/filter.c
[...]
case bpf_ctx_range_ptr(struct __sk_buff, flow_keys):
case bpf_ctx_range(struct __sk_buff, wire_len):
return false;
[...]
3) include/uapi/linux/bpf.h
Take the second chunk for the two cases each.
The main changes are:
1) Add support for BPF line info via BTF and extend libbpf as well
as bpftool's program dump to annotate output with BPF C code to
facilitate debugging and introspection, from Martin.
2) Add support for BPF_ALU | BPF_ARSH | BPF_{K,X} in interpreter
and all JIT backends, from Jiong.
3) Improve BPF test coverage on archs with no efficient unaligned
access by adding an "any alignment" flag to the BPF program load
to forcefully disable verifier alignment checks, from David.
4) Add a new bpf_prog_test_run_xattr() API to libbpf which allows for
proper use of BPF_PROG_TEST_RUN with data_out, from Lorenz.
5) Extend tc BPF programs to use a new __sk_buff field called wire_len
for more accurate accounting of packets going to wire, from Petar.
6) Improve bpftool to allow dumping the trace pipe from it and add
several improvements in bash completion and map/prog dump,
from Quentin.
7) Optimize arm64 BPF JIT to always emit movn/movk/movk sequence for
kernel addresses and add a dedicated BPF JIT backend allocator,
from Ard.
8) Add a BPF helper function for IR remotes to report mouse movements,
from Sean.

Currently only a single field in the representor private structure
is relevant for uplink representors. As a pre-step to allow adding
additional uplink representor fields, introduce uplink representor
private structure.
This is prepration step towards replacing egdev logic with the
indirect block notification mechanism. This patch doesn't change
any functionality.

mlx5-next shared branch with rdma subtree to avoid mlx5 rdma v.s. netdev
conflicts.
Highlights:
1) RDMA ODP (On Demand Paging) improvements and moving ODP logic to
mlx5 RDMA driver
2) Improved mlx5 core driver and device events handling and provided API
for upper layers to subscribe to device events.
3) RDMA only code cleanup from mlx5 core
4) Add helper to get CQE opcode
5) Rework handling of port module events
6) shared mlx5_ifc.h updates to avoid conflicts

Update the flow steering command formatting according to the extended
destination API.
Note that the FW dictates that multi destination FTEs that involve at
least one encap must use the extended destination format, while single
destination ones must use the legacy format.
Using extended destination format requires FW support. Check for its
capabilities and return error if not supported.

GRE RFC defines a 32 bit key field. NVGRE RFC splits the 32 bit
key field to 24 bit VSID (gre_key_h) and 8 bit flow entropy (gre_key_l).
Define the two key parsing alternatives in a union, thus enabling both
access methods.

Add explicit HW defined error values. For simplicity, keep counters for all
statuses starting from 0, although currently status=0 is not used.
Additionally, when HW signals an unexpected cable status, it is reported
now rather than ignored. And status counter is now updated on errors.

Several conflicts, seemingly all over the place.
I used Stephen Rothwell's sample resolutions for many of these, if not
just to double check my own work, so definitely the credit largely
goes to him.
The NFP conflict consisted of a bug fix (moving operations
past the rhashtable operation) while chaning the initial
argument in the function call in the moved code.
The net/dsa/master.c conflict had to do with a bug fix intermixing of
making dsa_master_set_mtu() static with the fixing of the tagging
attribute location.
cls_flower had a conflict because the dup reject fix from Or
overlapped with the addition of port range classifiction.
__set_phy_supported()'s conflict was relatively easy to resolve
because Andrew fixed it in both trees, so it was just a matter
of taking the net-next copy. Or at least I think it was :-)
Joe Stringer's fix to the handling of netns id 0 in bpf_sk_lookup()
intermixed with changes on how the sdif and caller_net are calculated
in these code paths in net-next.
The remaining BPF conflicts were largely about the addition of the
__bpf_md_ptr stuff in 'net' overlapping with adjustments and additions
to the relevant data structure where the MD pointer macros are used.

After the following flow counters API refactoring:
("net/mlx5: Use flow counter IDs and not the wrapping cache object")
flow counters private data structures mlx5_fc_cache and mlx5_fc are
redundantly exposed in fs_core.h, they have nothing to do with flow
steering core and they are private to fs_counter.c, this patch moves them
to where they belong and reduces their exposure in the driver.
