Tatyana Nikolova 1660a26adb i40iw: Do not retransmit MPA request after it is ACKed
The ACK packets for an MPA request are ignored and
the MPA request is retransmitted if the MPA reply
is late or missing. Fix this by checking ack_rcvd
variable before retransmitting a packet.

Shiraz Saleem f16dc0aa5e i40iw: Add support for port reuse on active side connections
During OpenMPI scale up testing, we observe rdma_connect
failures if ports are reused on multiple connections.
This is because the Control Queue-Pair (CQP) command to add
the reused port to Accelerated Port Bit VectorTable (APBVT)
fails as there already exists an entry.

Check for duplicate port before invoking the CQP command
to add APBVT entry and delete the entry only if the port
is not in use.

Mustafa Ismail d59659340c i40iw: Add missing cleanup on device close
On i40iw device close, disconnect all connected QPs by moving
them to error state; and block further QPs, PDs and CQs from
being created. Additionally, make sure all resources have been
freed before deallocating the ibdev as part of the device close.

packet in UDP loopback case. Remove the workaround as it is no
longer necessary.

Add support for QoS on QPs. Upon device initialization,
a map is created from user priority to queue set
handles. On QP creation, use ToS to look up the queue
set handle for use with the QP.
