Is there any interest in being able to configure the MTU settings for
the BMI-level devices via a config-file parameter?
For my current IB setup, I can get roughly 1/3rd (2Gbit/s+) better
performance by using an MTU of 2048 instead of the default of 1024, so
we do have a use for larger mtu's here. At this point the value is
hardcoded in the BMI devices, and would require a rebuild of the
binaries, so there would need to be some work done to get this to work
for each of the transport devices. It would be an interesting endeavor
to see the different performance implications this might bring about.
Just an idea I thought I'd throw out there.
