ibv_resize_cq - resize a completion queue (CQ)
#include <infiniband/verbs.h> int ibv_resize_cq(struct ibv_cq *cq, int cqe);
ibv_resize_cq() resizes the completion queue (CQ) cq to have at least cqe entries. cqe must be at least the number of unpolled entries in the CQ cq. If cqe is a valid value less than the current CQ size, ibv_resize_cq() may not do anything, since this function is only guaranteed to resize the CQ to a size at least as big as the requested size.
