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
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?
