umad_open_port - open InfiniBand device port for umad access
#include <infiniband/umad.h> int umad_open_port(char *ca_name, int portnum);
umad_open_port() opens the port portnum of the IB device ca_name for umad access. The port is selected by the library if not all parameters are provided (see umad_get_port() for details).
umad_open_port() returns 0 or an unique positive value of umad device descriptor on success, and a negative value on error as follows: -EOPNOTSUPP ABI version doesn't match -ENODEV IB device can't be resolved -EINVAL port is not valid (bad portnum or no umad device) -EIO umad device for this port can't be opened
