In datagram mode, the IB UD (Unreliable Datagram) transport is used so the MTU of the interface is equal to the IB L2 MTU minus the IPoIB encapsulation header. Any request to change the MTU value above the maximum range will change the MTU to the max allowed, but will not show any warning message. An ipoib_warn is issued in such cases, letting the user know that even though the value is legal, it can't be currently applied. Signed-off-by:
