[RFC PATCH V2 0/2] *** use rdma device capability to limit queue size ***

[Guixin Liu]

Hi guys,

Currently, the queue size if nvme over rdma is limited with a depth
of 128, we can use rdma device capability to limit it.

Changes from v1 to v2:
- use nvmet_ctrl's port to find rdma's nvmet_rdma_queue without change
  get_max_queue_size's param.
- additional clarification that the queue depth will be controlled within
  1024, rather than being very large.

Guixin Liu (2):
  nvmet: rdma: utilize ib_device capability for setting max_queue_size
  nvme: rdma: use ib_device's max_qp_wr to limit sqsize
