Re: [ewg] OFED 1.4.1 RC4 is delayed to Thursday

Comment #8 already identified the problem and a solution.
I think we would need to change the default value for
net.ipv4.neigh.ib0.unres_qlen to make it "permanent".

Subject: [PATCH ofed-1.4.1] documentation: update NFS-RDMA docs for
OFED1.4.1 (resend)

This updates the NFS-RDMA documentation to represent the increased
support for distro releases.  Additionally, it cleans up a few errors
and updates the port number.

Hi Tziporet,

Thanks for the update. Can we also get bug 1287 
 resolved? The OFA 
Interop Event has begun and this causes a failure that will have to be 
reported as part of the results on the OFA Logo site. We have both 
vendors and end users who seem to be concerned about IPoIB dropping 
packets and I think we should address it – it is a known problem 
discovered approximately one year ago.



Hi Rupert,
We have discussed this bug on Apr-6 meeting and I said that Mellanox 
will not be able to assign anyone to debug this now.

Qlogic said they will see if they can assign someone.
I cc John Russo from Qlogic - maybe they can help
