Subject: [PATCH] iw_cxgb4: set correct FetchBurstMax for QPs
Date: Fri, 3 Feb 2017 11:04:13 -0600	[thread overview]
Message-ID: <02ba01d27e3f$8b7c3c20$a274b460$@opengridcomputing.com> (raw)

I forgot to add the stable Cc tag when I submitted this, but it is important to
get this patch into 4.9.x:

commit b414fa01c31318383ae29d9d23cb9ca4184bbd86

    iw_cxgb4: set correct FetchBurstMax for QPs

    The current QP FetchBurstMax value is 256B, which
    is incorrect since a WR can exceed that value.  The
    result being a partial WR fetched by hardware, and
    a fatal "bad WR" error posted by the SGE.

    So bump the FetchBurstMax to 512B.

I'm not sure if this is the correct way to request this, but I think I'm
following _option_2 from Documentation/stable_kernel_rules.txt.


Thanks,

Steve.
