ibv_get_pkey_index3
Obtain the index in the p_key table of a p_key
Usage
-
#include <infiniband/verbs.h> int ibv_get_pkey_index(struct ibv_context *context, uint8_t port_num, __be16 pkey);
Overview
Every InfiniBand HCA maintains a P_Key table for each of its ports that is indexed by an integer and with a P_Key in each element. Certain InfiniBand data structures that work with P_Keys expect a P_Key index, e.g. struct ibv_qp_attr and struct ib_mad_addr. Hence the function ibv_get_pkey_index() that accepts a P_Key in network byte order and that returns an index in the P_Key table as result.
Return value
ibv_get_pkey_index() returns the P_Key index on success, and -1 on error.
