Re: [PATCH for-next 08/12] RDMA/bnxt_re: Fix FRMR issue with single page MR allocation

On Sun, Sep 12, 2021 at 11:15:22AM -0700, Selvin Xavier wrote:

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.
