The RDMA stack allows for applications to create IBV_QPT_RAW_PACKET
QPs, which receive plain Ethernet packets. This patch adds ibv_create_flow()
and ibv_destroy_flow() support in the bnxt_re lib. For now, only the
sniffer rule is supported to receive all port traffic. This is to support
tcpdump over the RDMA devices to capture the packets.
