Well, as expected this call is not documented ... and I get to it only with some help from Loic. On the version of MX I have tested it is not required to add the 3th and 4th arguments as I don't want to set anything. The NIC is already specified through the mx_btl->mx_endpoint isn't it ?

yes, a NIC ID is required for this call because a host may have multiple
NICs with different linespeeds, e.g. a 2G card and a 10G card.
