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
