So in theory the o2iblnd should never receive any RNR NAK. Therefore the rnr_retry_count option is not needed at all.</p> <p>I think:</p> <ul class="alternate" type="square"> <li>rnr_retry_count should be removed as a module option</li> <li>Just in case, add some code to issue warnings should RNR NAK is ever received.</li> </ul> LU-6594

The o2iblnd option rnr_retry_count should be removed
