HEADS UP: will merge VNET socket push back changes to stable/8

Hi, this is a heads up in case anyone is relying on this in private VNET modules or code. I am planning on merging this code to stable/8 probably during the weekend. It should be a NOP for almost everyone, especially if not running a VIMAGE kernel. /bz -- Bjoern A. Zeeb

Make 220.backup-pkgdb cd(1) and backup only the package database.

That should be plenty, but how large are your receive queues? \Kip On Thu, Apr 14, 2011 at 4:18 PM, Leon Meßner l.mess...@physik.tu-berlin.de wrote: On Thu, Apr 14, 2011 at 03:44:23PM +0200, K. Macy wrote: How many 9k jumbo clusters are available? Does this output suffice as information ?

Re: ixgbe(4) and Could not setup receive structures

If you get this message its only for one reason, you don't have enough mbufs to fill your rings. You must do one of two things, either reduce the number of queues, or increase the relevant mbuf pool. Increase the 9K mbuf cluster pool. Jack On Thu, Apr 14, 2011 at 6:05 AM, Leon Meßner

Re: ixgbe(4) and Could not setup receive structures

If you are using the latest code, then the RX ring size is set to be 2K descriptors, so you will use that many 9k jumbos per queue to initialize things. Having a spare amount free to use as you clean/refresh is needed also. I upped the ring size for performance reasons on 10G, its possible to try
