Hi Anish, I believe I tracked down why you were getting bounced and resolved it. We will see. > On Monday, July 6, 2015 at 5:40:24 PM UTC-7, Anish Bhatt wrote: > > I was trying to use the /sk_cgrp_prioidx/ value to find correct dcb > priority for iscsi (using /cgdcbxd/ + /cgrulesengd/ as recommended > by http://open-lldp.org/dcb_overview > <http://open-lldp.org/dcb_overview>).

We would prefer to make the skbuff smaller not larger at this point. If you can think up a more generic mechanism to add it to libiscsi without being overly intrusive that seems reasonable to me. At the moment I don't have any better suggestions. Thanks, John -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
