When the FRMR is allocated with single page, driver is attempting to create a level 0 HWQ and not allocating any page because the nopte field is set. This causes the crash during post_send as the pbl is not populated. To avoid this crash, check for the nopte bit during HWQ creation with single page and create a level 1 page table and populate the pbl address correctly.

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.
