This series adds rdmatool support for creating/deleting rdma links. This will be used, mainly, by soft rdma drivers to allow adding/deleting rdma links over netdev interfaces. It provides the user side for the following kernel changes merged in linux-5.1. Changes since v1: - move error receive checking from rd_sendrecv_msg() to rd_recv_msg(). - Add rd->suppress_errors to allow control over whether errors when reading a response should be ignored. Namely: resource queries can get errors like "none found" when querying for resources, and this error should not be displayed. So on a rd object basis, error suppression can be controlled. - Rebased on rdma/for-next UABI (no need to sync rdma_netlink.h now) - use chains of struct rd_cmd and rd_exec_cmd vs open coding the parsing for the 'link add' command. - minor nit resolution - added .mailmap file. If this is not desired for iproute2, then please drop the patch. Changes since RFC: - add rd_sendrecv_msg() and make use of it in dev_set as well as the new link commands. - fixed problems with the man pages - changed the command line to use "netdev" as the keyword for the network device, do avoid confused with the ib_device name. - got rid of the "type" parameter for link delete. Also pass down the device index instead of the name, using the common rd services for validating the device name and fetching the index.
