6ebbf4109f net/virtio-user: fix packed ring server mode
This patch fixes the situation where data path does not work properly
when vhost reconnects to virtio in server mode with packed ring.

Currently, virtio and vhost share memory of vring. For split ring, vhost
can read the status of descriptors directly from the available ring and
the used ring during reconnection. Therefore, the data path can
continue.

But for packed ring, when reconnecting to virtio, vhost cannot get the
status of descriptors via the descriptor ring. By resetting Tx
and Rx queues, the data path can restart from the beginning.

5efb18e85f vhost: fix deadlock on port deletion
If the vhost-user application (e.g. OVS) deletes the vhost-user
port while Qemu sends a vhost-user request, a deadlock can
happen if the request handler tries to acquire vhost-user's
global mutex, which is also locked by the vhost-user port
deletion API (rte_vhost_driver_unregister).

This patch prevents the deadlock by making
rte_vhost_driver_unregister() to release the mutex and try
again if a request is being handled to give a chance to
the request handler to complete.

Reset process may turn on the cancelled link state timer whether the
current port status is on or off, in order to solve this problem, this
patch add judge the current network port state before starting the
timer, only the port in the running state can start the link state
timer, so as to solve the problem that the link state timer accesses the
null pointer and causes the segment error.

a45fd0aa0e net/hns3: fix Rx queue search with broadcast packet
Currently, there is a certain probability of a type of RAS errors when
receiving broadcast packets. This type of RAS errors are parsed as
rx_q_search_miss error by hns3 PF PMD driver, the related log as below:
0000:bd:00.0 hns3_find_highest_level(): PPP_MFP_ABNORMAL_INT_ST2
rx_q_search_miss found [error status=0x20000000]

When receiving broadcast packet, network engine select which functions
need to accept it according to the function's promisc_bcast_en bit
configuration. And then search TQP_MAP configuration to select which
hardware queues the packet should enter, if can't find the target
hardware queue, network engine will trigger rx_q_search_miss RAS error.

The root cause as below:
1. VF's promisc_bcast_en bit configuration is not cleared by FLR reset,
   and the configuration has been set in the previous application.
2. There is one bug in setting TQP_MAP configuration in the
   initialization of PF device: when tqp is allocated to VF, it is still
   marked as PF.  This issue will affect the correctness of the TQP_MAP
   configuration.

This patch fixes it with the following modification.
1. Clear all VFs promisc_bcast_en bit in the initialization of PF
   device.
2. Fix the issue to ensure the correct TQP_MAP configuration.

ffd0ec015b net/hns3: add free threshold in Rx
This patch optimizes the Rx performance by adding the rx_free_thresh
related process in the '.rx_pkt_burst' ops implementation function named
hns3_recv_pkts. The related change as follows:
1. Adding the rx_free_thresh related process to reduce the number of
   writing the HNS3_RING_RX_HEAD_REG register.
2. Adjusting the internal macro named DEFAULT_RX_FREE_THRESH to 32 and
   adjusting HNS3_MIN_RING_DESC to 64 to make the effect of the thresh
   more obvious.

5cf7a75b2c net/hns3: remove one IO barrier in Rx
When receiving a packet, hns3 hardware network engine firstly writes the
packet content to the memory pointed by the 'addr' field of the Rx
Buffer Descriptor, secondly fills the result of parsing the packet
include the valid field into the Rx Buffer Descriptor in one write
operation, and thirdly writes the number of the Buffer Descriptor not
processed by the driver to the HNS3_RING_RX_FBDNUM_REG register.

This patch optimizes the Rx performance by removing one rte_io_rmb call
in the '.rx_pkt_burst' ops implementation function named hns3_recv_pkts.
The change as follows:
1. Driver no longer read HNS3_RING_RX_FBDNUM_REG register, so remove one
   rte_io_rmb call, and directly read the valid flag of Rx Buffer
   Descriptor to check whether the BD is ready.
2. Delete the non_vld_descs field from the statistic information of the
   hns3 driver because now it has become a common case that the valid
   flag of Rx Buffer Descriptor read by the driver is invalid.
