This patch adds a capability to place hairpin Rx queue in locked device memory. This capability is equivalent to storing hairpin RQ's data buffers in locked internal device memory. Hairpin Rx queue creation is extended with requesting that RQ is allocated in locked internal device memory. If allocation fails and force_memory hairpin configuration is set, then hairpin queue creation (and, as a result, device start) fails. If force_memory is unset, then PMD will fallback to allocating memory for hairpin RQ in unlocked internal device memory. To allow such allocation, the user must set HAIRPIN_DATA_BUFFER_LOCK flag in FW using mlxconfig tool.
