4f9f531e15 qed: Use dma_set_mask_and_coherent() and simplify code
Use dma_set_mask_and_coherent() instead of unrolling it with some
dma_set_mask()+dma_set_coherent_mask().

Moreover, as stated in [1], dma_set_mask() with a 64-bit mask will never
fail if dev->dma_mask is non-NULL.
So, if it fails, the 32 bits case will also fail for the same reason.

Simplify code and remove some dead code accordingly.

Now that qed_set_coherency_mask() is mostly a single call to
dma_set_mask_and_coherent(), fold it in its only caller.

b63c5478e9 ipv6: ioam: Support for Queue depth data field
v3:
 - Report 'backlog' (bytes) instead of 'qlen' (number of packets)

v2:
 - Fix sparse warning (use rcu_dereference)

This patch adds support for the queue depth in IOAM trace data fields.

The draft [1] says the following:

   The "queue depth" field is a 4-octet unsigned integer field.  This
   field indicates the current length of the egress interface queue of
   the interface from where the packet is forwarded out.  The queue
   depth is expressed as the current amount of memory buffers used by
   the queue (a packet could consume one or more memory buffers,
   depending on its size).

An existing function (i.e., qdisc_qstats_qlen_backlog) is used to
retrieve the current queue length without reinventing the wheel.

Note: it was tested and qlen is increasing when an artificial delay is
added on the egress with tc.

d7cd421da9 net/smc: Introduce TCP ULP support
This implements TCP ULP for SMC, helps applications to replace TCP with
SMC protocol in place. And we use it to implement transparent
replacement.

This replaces original TCP sockets with SMC, reuse TCP as clcsock when
calling setsockopt with TCP_ULP option, and without any overhead.

To replace TCP sockets with SMC, there are two approaches:

- use setsockopt() syscall with TCP_ULP option, if error, it would
  fallback to TCP.

- use BPF prog with types BPF_CGROUP_INET_SOCK_CREATE or others to
  replace transparently. BPF hooks some points in create socket, bind
  and others, users can inject their BPF logics without modifying their
  applications, and choose which connections should be replaced with SMC
  by calling setsockopt() in BPF prog, based on rules, such as TCP tuples,
  PID, cgroup, etc...

  BPF doesn't support calling setsockopt with TCP_ULP now, I will send the
  patches after this accepted.

Tony Lu says:

====================
RDMA device net namespace support for SMC

This patch set introduces net namespace support for linkgroups.

Path 1 is the main approach to implement net ns support.

Path 2 - 4 are the additional modifications to let us know the netns.
Also, I will submit changes of smc-tools to github later.

Currently, smc doesn't support net namespace isolation. The ibdevs
registered to smc are shared for all linkgroups and connections. When
running applications in different net namespaces, such as container
environment, applications should only use the ibdevs that belongs to the
same net namespace.

This adds a new field, net, in smc linkgroup struct. During first
contact, it checks and find the linkgroup has same net namespace, if
not, it is going to create and initialized the net field with first
link's ibdev net namespace. When finding the rdma devices, it also checks
the sk net device's and ibdev's net namespaces. After net namespace
destroyed, the net device and ibdev move to root net namespace,
linkgroups won't be matched, and wait for lgr free.

If rdma net namespace exclusive mode is not enabled, it behaves as
before.

Steps to enable and test net namespaces:

1. enable RDMA device net namespace exclusive support
	rdma system set netns exclusive # default is shared

2. create new net namespace, move and initialize them
	ip netns add test1
	rdma dev set mlx5_1 netns test1
	ip link set dev eth2 netns test1
	ip netns exec test1 ip link set eth2 up
	ip netns exec test1 ip addr add ${HOST_IP}/26 dev eth2

3. setup server and client, connect N <-> M
	ip netns exec test1 smc_run sockperf server --tcp # server
	ip netns exec test1 smc_run sockperf pp --tcp -i ${SERVER_IP} # client

4. netns isolated linkgroups (2 * 2 mesh) with their own linkgroups
  - server

0237a3a683 net/smc: Introduce net namespace support for linkgroup
Currently, rdma device supports exclusive net namespace isolation,
however linkgroup doesn't know and support ibdev net namespace.
Applications in the containers don't want to share the nics if we
enabled rdma exclusive mode. Every net namespaces should have their own
linkgroups.

This patch introduce a new field net for linkgroup, which is standing
for the ibdev net namespace in the linkgroup. The net in linkgroup is
initialized with the net namespace of link's ibdev. It compares the net
of linkgroup and sock or ibdev before choose it, if no matched, create
new one in current net namespace. If rdma net namespace exclusive mode
is not enabled, it behaves as before.

8d307f8e8c net: hns3: create new set of unified hclge_comm_cmd_send APIs
This patch create new set of unified hclge_comm_cmd_send APIs for PF and VF
cmdq module. Subfunctions called by hclge_comm_cmd_send are also created
include cmdq result check, cmdq return code conversion and ring space
opertaion APIs.

These new common cmdq APIs will be used to replace the old PF and VF cmdq
APIs in next patches.

0a7b6d2218 net: hns3: create new cmdq hardware description structure hclge_comm_hw
Currently PF and VF cmdq APIs use struct hclge(vf)_hw to describe cmdq
hardware information needed by hclge(vf)_cmd_send. There are a little
differences between its child struct hclge_cmq_ring and hclgevf_cmq_ring.
It is redundent to use two sets of structures to support same functions.

So this patch creates new set of common cmdq hardware description
structures(hclge_comm_hw) to unify PF and VF cmdq functions. The struct
hclge_desc is still kept to avoid too many meaningless replacement.

These new structures will be used to unify hclge(vf)_hw structures in PF
and VF cmdq APIs in next patches.

5f20be4e90 net: hns3: refactor hns3 makefile to support hns3_common module
Currently we plan to refactor PF and VF cmdq module. A new file folder
hns3_common will be created to store new common APIs used by PF and VF
cmdq module. Thus the PF and VF compilation process will both depends on
the hns3_common. This may cause parallel building problems if we add a new
makefile building unit.

So this patch combined the PF and VF makefile scripts to the top level
makefile to support the new hns3_common which will be created in the next
patch.

aa36c94853 net/mlx5: Set SMFS as a default steering mode if device supports it
Set SMFS (SW-managed flow steering) as a default steering mode
instead of DMFS (device-managed flow steering)

In SMFS, the driver writes the STEs (Steering Table Entries) directly
to the device's ICM, which allows for a higher rule insertion rate
than through using FW command interface, as it is done in DMFS.

SMFS/DMFS steering modes can be configured through devlink param
'flow_steering_mode'. The possible values are 'smfs' or 'dmfs'.
The desired 'flow_steering_mode' param value should be set before
enabling switchdev mode.

Example:

  # devlink dev param set pci/0000:05:00.0 name flow_steering_mode smfs
  # devlink dev eswitch set pci/0000:05:00.0 mode switchdev

When modifying TTL, packet's csum has to be recalculated.
Due to HW issue in ConnectX-5, csum recalculation for modify TTL
is supported through a work-around that is specifically enabled
by configuration.
If the work-around isn't enabled, ignore the modify TTL action
rather than adding an unsupported action.

cc2295cd54 net/mlx5: DR, Improve steering for empty or RX/TX-only matchers
Every matcher has RX and TX paths. When a new matcher is created, its RX
and TX start/end anchors are connected to the respective RX and TX anchors
of the previous and next matchers.
This creates a potential performance issue: when a certain rule is added
to a matcher, in many cases it is RX or TX only rule, which may create a
long chain of RX/TX-only paths w/o the actual rules.

This patch aims to handle this issue.

RX and TX matchers are now handled separately: matcher connection in the
matchers chain is split into two separate lists: RX only and TX only.
when a new matcher is created, it is initially created 'detached' - its
RX/TX members are not inserted into the table's matcher list.
When an actual rule is added, only its appropriate RX or TX nic matchers
are then added to the table's nic matchers list and inserted into its
place in the chain of matchers.
I.e., if the rule that is being added is an RX-only rule, only the RX
part of the matcher will be connected to the chain, while TX part of the
matcher remains detached and doesn't prolong the TX chain of the matchers.

Same goes for rule deletion: when the last RX/TX rule of the nic matcher
is destroyed, the nic matcher is removed from its list.
