Firmware FT pool is per device, but the software tracking of this pool
only services fs_chains users, and if another layer takes a flow table,
the pool will not be updated, and fs_chains will fail creating a flow
table, with no recovery till the flow table is returned.
Move FT pool to be global per device, and stored at the cmd level,
so all layers can use it.

Currently ASAP features fully utilize all the bits of the CQE's flow tag
and ft_metadata field. The flow tag field cannot be used because the
flow table tagging in FTE does not allow partial write.
We agree to reserve bit 31 of CQE's ft_metadata for IPsec to avoid
ASAP CT from dropping IPsec offloaded packet
Here is the new bit layout of REG_C1. Tunnel option id is reduced to

net/mlx5: Expose MPFS configuration API
MPFS is the multi physical function switch that bridges traffic between
the physical port and any physical functions associated with it. The
driver is required to add or remove MAC entries to properly forward
incoming traffic to the correct physical function.
We export the API to control MPFS so that other drivers, such as
mlx5_vdpa are able to add MAC addresses of their network interfaces.
The MAC address of the vdpa interface must be configured into the MPFS L2
address. Failing to do so could cause, in some NIC configurations, failure
to forward packets to the vdpa network device instance.
Fix this by adding calls to update the MPFS table.

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.

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.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
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
netdev if the packet was rx'd on a vlan. To keep the elimination of the
local variables requires a trivial edit to the code in -rc

pull-request: mlx5-next 2021-02-16
The patches in this pr are already submitted and reviewed through the
netdev and rdma mailing lists.
The series includes mlx5 HW bits and definitions for mlx5 real time clock
translation and handling in the mlx5 driver clock module to enable and
support such mode [1]

Internal timer mode (SW clock) requires some PTP clock related metadata
structs. Real time mode (HW clock) will not need these metadata structs.
This separation emphasize the different interfaces for HW clock and SW
clock.

Add needed structure layouts and defines for MTUTC (Management UTC)
register. MTUTC will be used for cyc2time HW translation.
In addition, add cyc2time modify capability bit and init segment HCA
real time address.
Finally, add capability bits indicating which time-stamping format is
supported per SQ and RQ. Add ts_format in the queue's context layout to
allow configuration.

* branch 'mlx5_timestamp':
RDMA/mlx5: Fail QP creation if the device can not support the CQE TS
net/mlx5: Add new timestamp mode bits
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.
