Jack Morgenstein bd85fbc203 net/mlx4_core: Zero out lkey field in SW2HW_MPT fw command 
When re-registering a user mr, the mpt information for the
existing mr when running SRIOV is obtained via the QUERY_MPT
fw command. The returned information includes the mpt's lkey.

This retrieved mpt information is used to move the mpt back
to hardware ownership in the rereg flow (via the SW2HW_MPT
fw command when running SRIOV).

The fw API spec states that for SW2HW_MPT, the lkey field
must be zero. Any ConnectX-3 PF driver which checks for strict spec
adherence will return failure for SW2HW_MPT if the lkey field is not
zero (although the fw in practice ignores this field for SW2HW_MPT).

Thus, in order to conform to the fw API spec, set the lkey field to zero
before invoking SW2HW_MPT when running SRIOV.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
