Re: Data Center Bridging?
Was there any progress made on DCB? We need a way to classify specific flows from the application and mark them with a priority. Not only do we need a bit of work on the driver, but also a way to tag frames all the way down to the driver. I imagine this would entail a socket option to mark a given flow and a mbuf flag to carry the request for priority classification to the driver. -Juan On Wed, Feb 6, 2013 at 5:53 AM, Randall Stewart r...@lakerest.net wrote: Lars/Jack: I am pretty sure that my company would be interested in it as well.. and I can help out here too ;-) Jack: are there particular versions of Intel cards that this needs to be on (we have both igb and ix cards in my office now).. thanks.

Re: Data Center Bridging?
No, I'm sorry but I've been kept very busy in development of our 40G driver, however, now that its complete we have been taking on a variety of other tasks, so this is one that I can have the team look into.

I have some student cycles that I can direct at helping with the implementation, if that's useful?

DCB is yet another attempt to 'fix' Ethernet, by eliminating queue overflow and providing bandwidth allocation on individual links. It was intended to be mostly about storage. Linux uses lldpad and dcbtool to manage the settings.
