Hi All,
Is anybody here use Infiniband on Fedora? More specifically IPoIB. I have two machines directly connected via IB, one running F23 and the other running F22. The IB card I have in both machines is a dual port Mellanox Technologies MT25418. Normally I can push about 9.8Gbit/sec between the two machines, however if I use a kernel newer than about v4.0.4 on the F22 machine or a kernel newer than about v4.2.3 on the F23 machine, the maximum transfer rate drops to 760K/sec.
Is this a kernel bug, or has something significantly changed?

Let's treat it as a bug -- can you file one, please?

Sure, no problem. I'll raise a bug and post back the BZ#.
