You can redirect flows with a particular port number. Thats the same as
port mappig right?

linux/include/rdma/ib_verbs.h:

struct ib_flow_spec_ipv4 {
        enum ib_flow_spec_type     type;
        u16                        size;
        struct ib_flow_ipv4_filter val;
        struct ib_flow_ipv4_filter mask;
};

struct ib_flow_tcp_udp_filter {
        __be16  dst_port;
        __be16  src_port;
};

struct ib_flow_spec_tcp_udp {
        enum ib_flow_spec_type        type;
        u16                           size;
        struct ib_flow_tcp_udp_filter val;
        struct ib_flow_tcp_udp_filter mask;
};

union ib_flow_spec {
        struct {
                enum ib_flow_spec_type  type;
                u16                     size;
        };
        struct ib_flow_spec_eth         eth;
        struct ib_flow_spec_ib          ib;
        struct ib_flow_spec_ipv4        ipv4;
