From: Yaacov Hazan <yaac...@mellanox.com> Seen with GCC < 4.6:
error: unknown field ?tcp_udp? specified in initializer error: extra brace group at end of initializer Static initialization of anonymous structs/unions is a C11 feature properly supported only since GCC 4.6. Work around compilation errors with older versions by expanding struct ibv_exp_flow_spec into struct hash_rxq_init.
