Actually it is v2.

v2..v1:
# Fixed git-check-log.sh issues
# Updated git comments for "when this issue happens?"
# Change the name of the patch
# Add Fixes tag

> Fix npa pool range errors observed while creating mempool, this issue
> happens when mempool objects are from different mem segments.
> 
> During mempool creation, octeontx2 mempool driver populates pool range
> fields before enqueuing the buffers. If any enqueue or dequeue operation
> reaches npa hardware prior to the range field's HW context update, those
> ops result in npa range errors. Patch adds a routine to read back HW context
> and verify if range fields are updated or not.
