Pull rdma updates from Jason Gunthorpe:
 "A usual cycle for RDMA with a typical mix of driver and core subsystem
  updates:

   - Driver minor changes and bug fixes for mlx5, efa, rxe, vmw_pvrdma,
     hns, usnic, qib, qedr, cxgb4, hns, bnxt_re

   - Various rtrs fixes and updates

   - Bug fix for mlx4 CM emulation for virtualization scenarios where
     MRA wasn't working right

   - Use tracepoints instead of pr_debug in the CM code

   - Scrub the locking in ucma and cma to close more syzkaller bugs

   - Use tasklet_setup in the subsystem

   - Revert the idea that 'destroy' operations are not allowed to fail
     at the driver level. This proved unworkable from a HW perspective.

   - Revise how the umem API works so drivers make fewer mistakes using
     it

   - XRC support for qedr

   - Convert uverbs objects RWQ and MW to new the allocation scheme

   - Large queue entry sizes for hns

   - Use hmm_range_fault() for mlx5 On Demand Paging

   - uverbs APIs to inspect the GID table instead of sysfs

   - Move some of the RDMA code for building large page SGLs into
     lib/scatterlist"

Merge branch 'dynamic_sg' into rdma.git for-next

2020-10-16T15:40:58+00:00

From Maor Gottlieb says:

====================
This series extends __sg_alloc_table_from_pages to allow chaining of new
pages to an already initialized SG table.

This allows for drivers to utilize the optimization of merging contiguous
pages without a need to pre allocate all the pages and hold them in a very
large temporary buffer prior to the call to SG table initialization.

The last patch changes the Infiniband core to use the new API. It removes
duplicate functionality from the code and benefits from the optimization
of allocating dynamic SG table from pages.

In huge pages system of 2MB page size, without this change, the SG table
would contain x512 SG entries.

Two minor conflicts:

1) net/ipv4/route.c, adding a new local variable while
   moving another local variable and removing it's
   initial assignment.

2) drivers/net/dsa/microchip/ksz9477.c, overlapping changes.
   One pretty prints the port mode differently, whilst another
   changes the driver to try and obtain the port mode from
   the port node rather than the switch node.

qede: Notify qedr when mtu has changed

2020-09-11T13:24:54+00:00

MTU change on ethtool is currently not supported for iWARP.  Notify qedr
driver so that appropriate logging can take place.

RDMA/qedr: Remove fbo and zbva from the MR

2020-09-11T13:24:54+00:00

zbva is always false, so fbo is never read.

A 'zero-based-virtual-address' is simply IOVA == 0, and the driver already
supports this.

net: qed: Disable aRFS for NPAR and 100G

2020-09-09T21:28:18+00:00

In CMT and NPAR the PF is unknown when the GFS block processes the
packet. Therefore cannot use searcher as it has a per PF database,
and thus ARFS must be disabled.

qed: use devlink logic to report errors

2020-08-25T01:01:33+00:00

Use devlink_health_report to push error indications.
We implement this in qede via callback function to make it possible
to reuse the same for other drivers sitting on top of qed in future.

qed: health reporter init deinit seq

2020-08-25T01:01:32+00:00

Here we declare health reporter ops (empty for now)
and register these in qed probe and remove callbacks.

This way we get devlink attached to all kind of qed* PCI
device entities: networking or storage offload entity.

qed/qede: make devlink survive recovery

2020-08-25T01:01:32+00:00

Devlink instance lifecycle was linked to qed_dev object,
that caused devlink to be recreated on each recovery.

Changing it by making higher level driver (qede) responsible for its
life. This way devlink now survives recoveries.

qede now stores devlink structure pointer as a part of its device
object, devlink private data contains a linkage structure,
qed_devlink.
