baef6bbfad app/testpmd: check statistics query before printing
In function 'fwd_stats_display', if function 'rte_eth_stats_get' fails,
'stats' is uncertainty value. The display result will be abnormal.

This patch check the return value of 'rte_eth_stats_get' to avoid
display abnormal stats.

93e1ea6dfa ethdev: fix RSS update when RSS is disabled
The RTE_ETH_MQ_RX_RSS_FLAG flag is a switch to enable RSS. If the flag
is not set in dev_configure, RSS will be not configured and enabled.
However, RSS hash and reta can still be configured by ethdev ops to
enable RSS if the flag isn't set. The behavior is inconsistent.

The 'rss_tuple_fields' in struct struct hns3_rss_conf::rss_tuple_sets is

75ccc3f3d7 net/hns3: fix RSS disable
Currently, hns3 PMD disable RSS by resetting redirection table when user
set rss_hf to 0 so as to all packets go to queue 0. The implementation
may cause following problems:
1) the same type packet may go to different queue on the case of
   disabling all tuples and partial tuples. The problem is determined by
   hardware design.
2) affect the configuration of redirection table and user experience.

For hns3 hardware, the packets with RSS disabled are always go to the
queue corresponding to first entry of the redirection table. Generally,
disable RSS should be implemented by disabling all tuples, This patch
fix the implementation.

0809d870fc net/tap: fix interrupt handler freeing
rte_pmd_tun/tap_probe() allocates pmd->intr_handle in eth_dev_tap_create()
and it should not be freed until rte_pmd_tap_remove() is called.

Inspection of tap_rx_intr_vec_set() shows that the call to
tap_tx_intr_vec_uninstall() was calling rte_intr_instance_free() but
tap_tx_intr_vec_install() can then be immediately called, and this then
uses pmd->intr_handle without it being reallocated.

Move rte_intr_instance_free() call from tap_tx_intr_vec_uninstall()
to rte_pmd_tap_remove().

733afb244d net/nfp: update how max MTU is read
The 'max_rx_pktlen' value was previously read from hardware, which was
set by the running firmware. This caused confusion due to different
meanings of 'MAX_MTU'. This patch updates the 'max_rx_pktlen' to the
maximum value that the NFP NIC can support. The 'max_mtu' value that is
read from hardware, is assigned to the 'dev_info->max_mtu' variable.

If more layer 2 metadata must be used, the firmware can be updated to
report a smaller 'max_mtu' value.

The constant defined for NFP_FRAME_SIZE_MAX is derived for the maximum
supported buffer size of 10240, minus 136 bytes that is reserved by the
hardware and another 56 bytes reserved for expansion in firmware. This
results in a usable maximum packet length of 10048 bytes.

1419e8d9d8 vhost: add unsafe API to check in-flight packets
In async data path, when vring state changes or device is destroyed,
it is necessary to know the number of in-flight packets in DMA engine.
This patch provides a thread unsafe API to return the number of
in-flight packets for a vhost queue without using any lock.
