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

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 ? -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
