Subject: rdma: Set pointer to device name position
X-Git-Tag: v4.16.0~66
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6e0de6e886571cab7787f9b809b6db5e05b2444c;p=thirdparty%2Fiproute2.git

rdma: Set pointer to device name position

The dev and link execution callbacks expects that next
command line argument is device or port name.

Set pointer to device or port name position prior calls to
rd_exec_dev()/rd_exec_link().
