alloc_ordered_workqueue() with WQ_MEM_RECLAIM set, replaces
deprecated create_singlethread_workqueue(). This is the identity
conversion.
The workqueue "virtchnl_wq" queues work items i40iw_cqp_generic_worker
and i40iw_cqp_manage_hmc_fcn_worker. It has been identity converted.
WQ_MEM_RECLAIM has been set to ensure forward progress under memory
pressure.

When LAG is active, QP tx affinity (the physical port
to which a QP is affined, or the TIS in case of raw-eth)

When LAG is active, port up/down events should be triggered
by tracking the LAG master, and not one of the two slave

In the same manner, ib_query_port() should return the details

This is done in two steps:
1) Issuing CREATE_VPORT_LAG in order to have Ethernet traffic from
both ports arriving on PF0 root flowtable, so we will be able to catch
all raw-eth traffic on PF0.
2) Creation of LAG demux flowtable in order to direct all non-raw-eth
traffic back to its source port, assuring that normal Ethernet
traffic "jumps" to the root flowtable of its RX port (non-LAG behavior).

Since ib_query_port() in RoCE returns the state of its netdev as the port
state, it makes sense to propagate the port up/down events to ib_core
when the netdev port state changes, instead of relying on traditional
core events.
This also keeps both the event and ib_query_port() synchronized.

identify whether hem memory released or not.
If all context in a hem memory released, the related hem memory will be
released by driver and reused by others. But, hardware don't know that
this memory can't be used already.
In order to fix this bug, hns roce driver reserved 128K memory for each
