Pull rdma updates from Jason Gunthorpe:
"This is significantly bug fixes and general cleanups. The noteworthy
new features are fairly small:
- XRC support for HNS and improves RQ operations
- Bug fixes and updates for hns, mlx5, bnxt_re, hfi1, i40iw, rxe, siw
and qib
- Quite a few general cleanups on spelling, error handling, static
checker detections, etc
- Increase the number of device ports supported beyond 255. High port
count software switches now exist
- Several bug fixes for rtrs
- mlx5 Device Memory support for host controlled atomics
- Report SRQ tables through to rdma-tool"

mlx5_is_roce_enabled returns the devlink RoCE init value, therefore it
should be used only when driver is loaded. Instead we just need to read
the roce_en field.
In addition, rename mlx5_is_roce_enabled to mlx5_is_roce_init_enabled.

Total vports are already stored during eswitch initialization. Instead
of calculating everytime, read directly from eswitch.
Additionally, host PF's SF vport information is available using
QUERY_HCA_CAP command. It is not available through HCA_CAP of the
eswitch manager PF.
Hence, this patch prepares the return total eswitch vport count from the
existing eswitch struct.
This further helps to keep eswitch port counting macros and logic within
eswitch.

mlx5_eswitch_get_total_vports() doesn't honor MLX5_ESWICH Kconfig flag.
When MLX5_ESWITCH is disabled, FS layer continues to initialize eswitch
specific ACL namespaces.
Instead, start honoring MLX5_ESWITCH flag and perform vport specific
initialization only when vport count is non zero.

When using SW steering, rule insertion rate depends on the RDMA RC QP
performance used for writing to the ICM. During stress this QP is competing
on the HW resources with all the other QPs that are used to send data.
To protect SW steering QP's performance in such cases, we set this QP to
use isolated VL. The VL number is reserved by FW and is not exposed to the
driver.
Support for this QP on isolated VL exists only when both force-loopback and
isolate_vl_tc capabilities are set.

Striding RQ attributes below are mutually dependent. An unaware
change to one might take the others out of the valid range derived
by the HW caps:
- The MPWQE size in bytes
- The number of strides in a MPWQE
- The stride size
Add checks to verify they are valid and comply to the HW spec
and SW assumptions/requirements.
This is not a fix, no particular issue exists today.

These new fields declare the number of MSI-X vectors that is possible to
allocate on the VF through PF configuration.
Value must be in range defined by min_dynamic_vf_msix_table_size and
max_dynamic_vf_msix_table_size.
The driver should continue to query its MSI-X table through PCI
configuration header.

Currently we are allocating high-order page for EQs. In case of
fragmented system, VF hot remove/add in VMs for example, there isn't
enough contiguous memory for EQs allocation, which results in crashing
of the VM.
Therefore, use order-0 fragments for the EQ allocations instead.

Currently reg_c0 lower 16 bits and reg_b are used to store the chain
id that missed in FDB and NIC tables accordingly. However, the
registers' values may index a restore object, rather than a single u32
value. Different object types can be used to restore mutually exclusive
contexts such as chain id and sample group id.
Use the mapping object to associate an index with a restore object
as a prestep for supporting additional restore types.

Hence, pack the structure and avoid the wastage.

QPs which don't care from timestamp mode, should set the ts_format
to default, otherwise the QP creation could be failed if the timestamp
mode is not supported.

When changing profiles we reset the mlx5e priv but we should still

Pull rdma updates from Jason Gunthorpe:
"This is quite a small cycle, if not for Lee's 70 patches cleaning the
kdocs it would be well below typical for patch count.
Most of the interesting work here was in the HNS and rxe drivers which
got fairly major internal changes.
Summary:
- Driver updates and bug fixes: siw, hns, bnxt_re, mlx5, efa
- Significant rework in rxe to get it ready to have XRC support added
- Several rts bug fixes
- Big series to get to 'make W=1' cleanness, primarily updating kdocs
- Support for creating a RDMA MR from a DMABUF fd to allow PCI peer
to peer transfers to GPU VRAM
- Device disassociation now works properly with umad
- Work to support more than 255 ports on a RDMA device
- Further support for the new HNS HIP09 hardware
- Coding style cleanups: comma to semicolon, unneded semicolon/blank
lines, remove 'h' printk format, don't check for NULL before kfree,
use true/false for bool"

The final logic is to call rxe_get_dev_from_net() again with the master

The traditional DevX CQ creation flow goes through mlx5_core_create_cq()
which checks that the given EQN corresponds to an existing EQ and attaches
a devx handler to the EQN for the CQ.
In some cases the EQ will not be a kernel EQ, but will be controlled by
modify CQ, don't block creating these just because the EQN can't be found
in the kernel.

Cleanup the synchronize_srcu() from the ODP flow as it was found to be a
very heavy time consumer as part of dereg_mr.
For example de-registration of 10000 ODP MRs each with size of 2M hugepage
took 19.6 sec comparing de-registration of same number of non ODP MRs that
took 172 ms.
The new locking scheme uses the wait_event() mechanism which follows the
use count of the MR instead of using synchronize_srcu().
By that change, the time required for the above test took 95 ms which is
even better than the non ODP flow.
Once fully dropped the srcu usage, had to come with a lock to protect the
XA access.
As part of using the above mechanism we could also clean the
num_deferred_work stuff and follow the use count instead.

Previous patch in series that implements stack devices RX path implements
indirect table rules that match on tunnel VNI. After such rule is created
all tunnel traffic is recirculated to root table. However, recirculated
packet might not match on any rules installed in the table (for example,
when IP traffic follows ARP traffic). In that case packets appear on
representor of tunnel endpoint VF instead being redirected to the VF
itself.
Extend slow table with additional flow group that matches on reg_c0 (source
port value set by indirect tables implemented by previous patch in series)
and reg_c1 (special 0xFFF mark). When creating offloads fdb tables, install
one rule per VF vport to match on recirculated miss packets and redirect
them to appropriate VF vport. Modify indirect tables code to also rewrite
reg_c1 with special 0xFFF mark.
Implementation reuses reg_c1 tunnel id bits. This is safe to do because
recirculated packets are always matched before decapsulation.

Following patch in series uses reg_c1 in eswitch code. To use reg_c1
helpers in both TC and eswitch code, refactor existing helpers according to
similar use case of reg_c0 and move the functionality into eswitch.h.
Calculate reg mappings length from new defines to ensure that they are
always in sync and only need to be changed in single place.
