Hi, Doug Ledford
In hns_roce_cmd_wait and hns_roce_cmd_poll, there are down&up
seminal operations,
So, there are not deadlock and conflict, right?
static int hns_roce_cmd_poll(struct hns_roce_dev *hr_dev, u64 in_param,
u64 *out_param, unsigned long in_modifier

This patch was implementing for queue pair operations. QP Consists
of a Send Work Queue and a Receive Work Queue. Send and receive
queues are always created as a pair and remain that way throughout
their lifetime. A Queue Pair is identified by its Queue Pair Number.
QP operations as follows:
1.
