Yes, I know how to do DOA testing. > What we do know that needs fixing for 4.3-rc >=20 > --> RoCE, you need the patch re-posted by Haggai few hours ago > "IB/cma: Accept connection without a valid netdev on RoCE" -- without > it, RoCE isn't working. I have that already.

The 0day testing just came back and it's all good. --=20 Doug Ledford GPG KeyID: 0E572FDD --3ns9kPCKT183D2PsL3gq55Mi0GRMR6g2H Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJWFDyOAAoJELgmozMOVy/doEoP/3um9rNsEITRHgS83yAJZ/+0 Az1AqvHEH/jofl8ha1Q95R47UIs3PZWCwE5GLzdSfdQiRqDX/BK0e0qCmsoh1nT8 b2CbzTtMpHA893Q04Tkz0G8r+YYESSP1WdXCVX2YAxNe2F9v7SdgOrYoA5U1XKDH Nt4ni/XMj6J8tTl+Oe+YhtMdXf3TJEbMiR05OKYP4IT7KlPpeoHqU9Gv+mF2GX/2 haHU8TVZ4nU2q3CmctodCrh1D7OC0piQ7uIG0eLYbyppTZUsYjZ2ff9qdFe95V61 RQN3o/ho7T2C0XmC4pc8xDdHBh4oMVXOaFQY9JG5BWBTlU4OwqicCY3grntbs/g1 hl53YikcUwSb9VcUtMZsRcCUef0neLKe1owaPdv79zmtnIzl+LADQZVI4Mx5Wx+C U/2wTywxe1fguu1QJJ9qqE5EdiKcPo5sBwivv4AKZ8tmew0IHMVPsQigCZTcA42S FaCpLxyp8b7JKA/YB6lQYkS63RKq2kJeQkcej/GZopG4KcauqmFdqIDeAv9PGORS G6EXxBlt26kmjC2dCEkB22yu1VO5p0ynR4h6c2znapXiMs9b6UimXLKf4VO7EIgf 1IIR+P2+bqouoTQPGNaNnYIVxbzwIJTTtuLt6zGV3yFS33nzIkjfXqUNw2wHY4Vb Ix6XSbJTAFKGwiXcuqjZ =Av7I -----END PGP SIGNATURE----- --3ns9kPCKT183D2PsL3gq55Mi0GRMR6g2H-- -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
