umad_get_smi_gsi_pairs(3) =========================Get CAs as SMI/GSI pairs.Synopsis ‐‐‐‐‐‐‐‐    #include <infiniband/umad.h>    int  umad_get_smi_gsi_pairs(struct umad_ca_pair cas[], size_tmax);Description ‐‐‐‐‐‐‐‐‐‐‐‘‘umad_get_smi_gsi_pairs()‘‘  fills  a  user‐allocated  array  of‘‘struct umad_ca_pair‘‘.  It fills up to ‘‘max‘‘ devices.The  argument  ‘‘cas‘‘  is an array of ‘‘struct umad_ca_pair‘‘ asspecified in ‘‘<infiniband/umad.h>‘‘:    struct umad_ca_pair {        char smi_name[UMAD_CA_NAME_LEN];        /* Name of the SMI */        uint32_t smi_preferred_port;        /* Preferred port for the SMI */        char gsi_name[UMAD_CA_NAME_LEN];        /* Name of the GSI */        uint32_t gsi_preferred_port;        /* Preferred port for the GSI */    };The ‘‘smi_preferred_port‘‘ and ‘‘gsi_preferred_port‘‘ fields rep‐resent the first ports found active for the corresponding SMI/GSIdevice.Return Value ‐‐‐‐‐‐‐‐‐‐‐‐‘‘umad_get_smi_gsi_pairs()‘‘  returns  the  number   of   devicesfilled, or **‐1** on error.Authors ‐‐‐‐‐‐‐‐ Asaf Mazor <amazor@nvidia.com>
