One way to set or check mtu is with the ibportstate utility:

Usage: ibportstate [options] <dest dr_path|lid|guid> <portnum> [<op>]
Supported ops: enable, disable, reset, speed, width, query, down, arm,
active, vls, mtu, lid, smlid, lmc

> Not directly.  The ipoib mtu is usually set based on the mtu of the IB
link.  The latter does affect rsocket performance.  However if the ipoib mtu
is changed separately from the IB link mtu, it will not affect rsockets.

Actually i'm going faster with IPoIB than rsockets.
How can I change the MTU for IB link ?
