We need community input here or some direction from the co-chairs (Woody and Vlad) so we can move forward. I have no problem waiting for a fix if someone can give the EWG a timely ETA on an upstream fix. From what I can tell, the maintainer doesn't have the bandwidth and DDN doesn't have the expertise to fix so I don't see any quick resolution. There are several OFA members anxiously waiting for OFED 4.8-1 to add their new drivers and many that need to get OFED 4.8 GA done. Not sure we can wait weeks and/or months for this to get resolved.
The EWG meeting next Monday is on a US holiday and will be cancelled so we don't want to wait 2 weeks for a decision. I am asking EWG and OFA members to please reply with their recommendations and suggestions. We are clearly at an impasse. > -----Original Message----- > From: Woodruff, Robert J > Sent: Thursday, June 29, 2017 1:25 PM > To: Davis, Arlin R <arlin.r.da...@intel.com>; Vladimir Sokolovsky > <v...@dev.mellanox.co.il>; Bart Van Assche <bart.vanass...@wdc.com>; > rsda...@soft-forge.com; Hanania, Amir <amir.hana...@intel.com>; > mschlin...@ddn.com > Cc: mda...@ddn.com; ewg@lists.openfabrics.org; cfernan...@ddn.com > Subject: RE: [ewg] [GIT PULL compat-rdma] qib for OFED 4.8 > > I know that DDN really wants to hold the release until a fix is available.
