Justin-san,
Thank you so much. Finally, I've solved problem with driving MCX353A-FCBT with Fedora18 instead of Fedora16.
I've confirmed that it works also with Fedora19.
The solutions is that we should use following packages for Fedora 18 or later instead of OFED.
infiniband-diags-1.6.1-4.fc18.x86_64
opensm-3.3.15-6.fc18.x86_64
mstflint-1.4-8.fc18.x86_64
Still they don't include scripts of OFED, we can configure IB ULP services (such as IPoIB) by writing scripts, for example
echo connected > /sys/class/net/ib0/mode
We still continue improving socket communication performance with IPoIB-CM. Now we see about 7.8Gbps
of TCP bandwidth with IPoIB-CM and MTU=65520 configuration.
Anyway, thank you so much for your giving good advice to us.
