In FW default settings, Ethertype 0x88A8 is treated as S-TAG,

However, Port Virtualizer mode is not initialized in DPDK, so X710 will

This patch fixes this issue by turning off S-TAG identification.

The statistics counters are based on RFC 2819 and RFC 2863 as follows:
rx/tx_good_packets
rx/tx_total_bytes
rx/tx_missed_pkts
rx/tx_broadcast_packets
rx/tx_multicast_packets

rx/tx_1523_to_max_packets;
rx/tx_errors
rx_fragmented_errors
rx_jabber_errors
rx_unknown_protos_packets;
No API is changed or added.
rte_eth_xstats_get_names() to retrieve what kinds of vhost xstats are
supported,
rte_eth_xstats_get() to retrieve vhost extended statistics,
rte_eth_xstats_reset() to reset vhost extended statistics.
The usage of vhost pmd xstats is the same as virtio pmd xstats.
for example, when test-pmd application is running in interactive mode
vhost pmd xstats will support the two following commands:
show port xstats all | port_id will show vhost xstats
clear port xstats all | port_id will reset vhost xstats
net/virtio pmd xstats(the function virtio_update_packet_stats) is used

The root cause is that vpp-vhost-user translates the message
VHOST_USER_SET_FEATURES as puting this device into init state,
aka, zero all related structures. However, previous code
puts this message at last in the whole initialization process,
which leads to all previous information are zeroed.
To fix this issue, we rearrange the sequence of those messages.
- step 0, send VHOST_USER_SET_VRING_CALL so that vhost allocates
virtqueue structures;
- step 1, send VHOST_USER_SET_FEATURES to confirm the features;

The driver is incorrectly setting the RSS field in the last mbuf in
the packet chain instead of the first. Moreover, the last mbuf might
have already been freed if it only contained the Ethernet CRC.
Also, fix the call to i40e_rxd_build_fdir to store the fdir flags in
the first mbuf of the chain instead of the last.

VSI structure needs to be removed from TAILQ list when releasing.
But for the child VSI it will be removed again after the structure
is freed. It will cause core dump when the DPDK i40e using as PF
host driver.
This patch fixes it to only remove child VSI from TAILQ before
send adminq command to remove it from hardware.

i40e driver was removing elements when iterating tailq lists
with TAILQ_FOREACH macro, which is not safe.
It is especially visible since the memory is zeroed on free
(commit ea0bddbd14).
Instead, TAILQ_FOREACH_SAFE macro is used when removing/freeing
these elements.

The commit cb6696d220 ("drivers: update registration macro usage")
changes the name from virtio-user to virtio_user, because hyphen
cannot be used in a C symbol name. However, this commit does not
update the strings in docs and source code, which could lead to
failure to start this device as per the docs.
This patch updates related strings in the docs and source code.

Sometimes app just wants to update the RSS hash function and no RSS key
update is needed, but fm10k pmd will return EINVAL for this case.
If the rss_key is NULL, we don't need to check the rss_key_len.

Rx loop inside _recv_raw_pkts_vec() ignores nb_pkts argument and always
tries to receive RTE_I40E_VPMD_RX_BURST (32) packets. This is a violation
of rte_eth_rx_burst() API and can lead to memory corruption (out-of-bounds
writes to struct rte_mbuf **rx_pkts) if nb_pkts is less than 32.
Fix this by actually using nb_pkts inside the loop.

Initialize the mbuf data offset to RTE_PKTMBUF_HEADROOM as the
enic takes ownership of them. If allocated mbufs had some offset
other than RTE_PKTMBUF_HEADROOM, the application would read mbuf

The support of virtio-user changed the way the mbuf dma address is
retrieved, using a physical address in case of virtio-pci and a virtual
address in case of virtio-user.
This change introduced some possible memory corruption in packets,
replacing:
m->buf_physaddr + RTE_PKTMBUF_HEADROOM
by:
m->buf_physaddr + m->data_off (through a macro)
This patch fixes this issue, restoring the original behavior.
By the way, it also rework the macros, adding a "VIRTIO_" prefix and
API comments.
