I certainly won't get it done before the holiday break coming up (Red
Hat, and by extension, myself, have a 1 week shutdown over the holiday
season, so I'll be offline starting this Friday).

However, even though you changed the api filename, there is still a lot
of inconsistency in the naming of your files.  The module itself is
bnxt_re, not bnxtre or any other variant.  Please make all uses of
bnxtre or other variants match bnxt_re.  This includes the api file that
you just moved.  I also want the directory in drivers/infiniband/hw to
be bnxt_re not bnxtre.  Also, putting bnxt_re as part of the file name
for files already in the bnxt_re directory is redundant (all except for
bnxt_re.h, where it is appropriate).  Just name the files things like
main.c and ib_verbs.c.  And for the qplib files, drop the bnxt_ prefix
and just use qplib_*.

I'll make other comments as I sort through the files, but those are
things I would like to see changed so I wanted to get that feedback to
you sooner rather than later.
