Steven Hartland 4be723f63e Fix vtnet hang with max_virtqueue_pairs > VTNET_MAX_QUEUE_PAIRS ... Correctly limit npairs passed to vtnet_ctrl_mq_cmd. This ensures that VQ_ALLOC_INFO_INIT is called with the correct value, preventing the system from hanging when max_virtqueue_pairs > VTNET_MAX_QUEUE_PAIRS. Add new sysctl requested_vq_pairs which allow the user to configure the requested number of virtqueue pairs. The actual value will still take into account the system limits. Also missing sysctls for the current tunables so their values can be seen. PR: 207446 Reported by: Andy Carrel MFC after: 3 days Relnotes: Yes Sponsored by: Multiplay		2016-08-11 21:13:58 +00:00
