From: Yaacov Hazan <yaacovh at 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.
