Virtio interfaces do not currently allow the user to specify a particular
Maximum Transmission Unit (MTU). Consequently, the MTU of Virtio interfaces
is typically set to the Ethernet default value of 1500.
This is problematic in the case of cloud deployments, in which a specific
(and potentially non-standard) MTU needs to be set by a DHCP server, which
needs to be honored by all interfaces across the traffic path.To acheive
this Virtio interfaces should support setting of MTU.
In case when GRE/VXLAN tunneling is used for internal communication, there
will be an overhead added by the infrastructure in the packet over and
above the ETHER MTU of 1518. So to take care of this overhead in these
cases the DHCP server corrects the L3 MTU to 1454. But since virtio
interfaces was not having the MTU set functionality that MTU sent by the
DHCP server was ignored and the instance will still send packets with 1500
MTU which after encapsulation will become more than 1518 and eventually
gets dropped in the infrastructure.
By adding an additional 'set_mtu' function to the Virtio driver, we can
honor the MTU sent by the DHCP server. The dhcp server/controller can
then leverage this 'set_mtu' functionality to resolve the above
mentioned issue of packets getting dropped due to incorrect size.

reconfigure and re-start the port.
During reconfigure, if there is an existing memzone, driver will reuse
it. But reconfigure may request different number of Tx/Rx queues.
This results in a memzone with wrong size and potential invalid memory
access.
To fix this, free the memzone if found and reserve a new one.

This feature adds vhost pmd extended statistics from per port perspective
in order to meet the requirements of the applications such as OVS etc.
RX/TX xstats count the bytes without CRC. This is different from physical
NIC stats with CRC.
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_unicast_packets
rx/tx_undersize_errors
rx/tx_size_64_packets
rx/tx_size_65_to_127_packets;
rx/tx_size_128_to_255_packets;
rx/tx_size_256_to_511_packets;
rx/tx_size_512_to_1023_packets;
rx/tx_size_1024_to_1522_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
as reference when implementing the feature.

In some cases when using the vHost PMD, certain vHost library functions
may still need to be accessed. One such example is the

Interestingly, clang and gcc has different prototype for _mm_prefetch().
For gcc, we have
_mm_prefetch (const void *__P, enum _mm_hint __I)
While for clang, it's
#define _mm_prefetch(a, sel) (__builtin_prefetch((void *)(a), 0, (sel)))
That's how the following error comes with clang:
error: cast from 'const void *' to 'void *' drops const qualifier

of code to another file, nothing else changed.
This patch fix the issue when Jerin's patchset is applied. Thus, I think

When virtio_user is used with VPP's native vhost user, it cannot
send/receive any packets.
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;
- step 2, send VHOST_USER_SET_MEM_TABLE to share mem regions;
- step 3, send VHOST_USER_SET_VRING_NUM, VHOST_USER_SET_VRING_BASE,
VHOST_USER_SET_VRING_ADDR, VHOST_USER_SET_VRING_KICK for each

Call stack is as following:

The array used as source buffer in virtio_xmit_cleanup (free) is a
pointer array with 32 elements, in 32bit this makes 128 bytes.
in rte_memcpy() implementation, there a code piece as following:
if (size > 256) {
rte_move128(...);
rte_move128(...); <--- [1]
....
}
The compiler traces the array all through the call stack and knows the
size of array is 128 and generates a warning on above [1] which tries to
access beyond byte 128.
But unfortunately it ignores the "(size > 256)" check.
Giving a hint to compiler that variable "size" is related to the size of
the source buffer fixes compiler warning.

The enic PMD was using the same variables in the enic structure to
track two different things. Initially rq_count, wq_count, cq_count,
and intr_count were set to the values obtained from the VIC adapters
as the maximum resources allocated on the VIC, then in
enic_set_vnic_res(), they were set to the counts of resources actually
used, discarding the initial values. The checks in enic_set_vnic_res()
were technically incorrect if it is called more than once on a port,
which happens when using bonding, but were harmless in practice as the
checks couldn't fail on the second call.
The enic rx-scatter patch misunderstood the subtleties of
enic_set_vnic_res(), and naively added a multiply by two to the
rq_count check. This resulted in the rq_count check failing when
enic_set_vnic_res() was called a second time, ie when using bonding.
This patch adds new variables to the enic structure to track the
maximum resources the VIC is configured to provide so that the
information isn't later lost and calls to enic_set_vnic_res() do
the expected thing.

We find that when traffic is light, a small number of packets will have
wrong metadata (e.g. packet type), however this issue will not happen
when traffic is heavy.
The root cause is some fields in fm10k_rx_desc are read at the wrong time,
since the descriptor (being 16-bytes big) is not read as a single atomic
operation. When the input speed is slower than software's capability,
fm10k scalar Rx function accesses descriptors at about the same time
as HW writes them, so the scenario can occur: some fields like pkt_info
in fm10k_rx_desc are read before HW writeback but some fields like DD bit
are read after HW writeback, this will lead to the later packet parsing
function using incorrect value.
This patch fixes this issue by reading and parsing Rx descriptor only after
first checking that the DD bit is set.

Modify the PMD_REGISTER_DRIVER macro, adding a name argument to it. The
addition of a name argument creates a token that can be used for subsequent
macros in the creation of unique symbol names to export additional bits of
information for use by the pmdinfogen tool. For example:
PMD_REGISTER_DRIVER(ena_driver, ena);
registers the ena_driver struct as it always did, and creates a symbol
const char this_pmd_name0[] __attribute__((used)) = "ena";
which pmdinfogen can search for and extract. The subsequent macro
DRIVER_REGISTER_PCI_TABLE(ena, ena_pci_id_map);
creates a symbol const char ena_pci_tbl_export[] __attribute__((used)) =
"ena_pci_id_map";
Which allows pmdinfogen to find the pci table of this driver
Using this pattern, we can export arbitrary bits of information.
pmdinfo uses this information to extract hardware support from an object
file and create a json string to make hardware support info discoverable
later.

Instead, traffic can be sent from one VF to another using the floating
VEB - even when the physical link on the NIC port is down.
This patch adds floating VEB options in the devargs for i40e driver.
Using these parameters, applications can decide whether to use legacy
VEB/VEPA or a floating VEB.
To enable this feature, the user should pass a devargs parameter to the
EAL, for example "-w 84:00.0,enable_floating_veb=1", to control whether
the PMD will to use the floating VEB feature or not.
Once the floating VEB feature is enabled, all the VFs created by
this PF device are connected to the floating VEB.
NOTE: The floating VEB functionality requires a NIC firmware version
of 5.0 or greater.

The standard Virtual Ethernet Bridge(VEB) definition in 1Qbg is a bridge

but a "floating" VEB is a special VEB without an uplink port to the
outside. Instead, traffic can be sent from one VF to another using the

VFs VSIs connect either to the standard VEB/VEPA or to the floating VEB,
they cannot connect to both of them. The PF, VMDQ and FD VSIs still

Provide an update MTU callback. The function returns -ENOTSUP
if Rx scatter is enabled. Updating the MTU to be greater than

Pull in common VNIC code which enables querying for max egress
packet size with newer firmware via a device command. If the
field is non-zero, it is the max egress packet size. If it is
0, the default value (9022) can safely be assumed. The value
for 1300 series VICS using firmware versions >= 3.1.2 for blade
series and >= 2.0.13 for rack series servers is 9208.
Tx buffers can be emitted only if they are less than the max egress
packet size regardless of the MTU setting (the MTU is advisory).
The max egress packet size can used to determine the upper limit
of the MTU since the enic can also receive packets of size greater
than max egress packet size. A max_mtu variable is added with
a value of max egress packet size minus L2 header size.
The default MTU is set via the CIMC/UCSM management interface and
currently allows value up to 9000. If the value is changed, the
host must be reboot. To avoid the reboot and allow MTU values
up to the max capability of the NIC, MTU update capability will
be added with a max value capped by max_mtu.

This commit brings back Rx scatter and related support by the MTU update
function. The maximum number of segments per packet is not a fixed value
anymore (previously MLX5_PMD_SGE_WR_N, set to 4 by default) as it caused
performance issues when fewer segments were actually needed as well as
limitations on the maximum packet size that could be received with the
default mbuf size (supporting at most 8576 bytes).
These limitations are now lifted as the number of SGEs is derived from the
MTU (which implies MRU) at queue initialization and during MTU update.

The primary purpose of rxq_rehash() function is to stop and restart
reception on a queue after re-posting buffers. This may fail if the array
that temporarily stores existing buffers for reuse cannot be allocated.
Update rxq_rehash() to work on the target queue directly (not through a
template copy) and avoid this allocation.
rxq_alloc_elts() is modified accordingly to take buffers from an existing
queue directly and update their refcount.
Unlike rxq_rehash(), rxq_setup() must work on a temporary structure but
should not allocate new mbufs from the pool while reinitializing an
existing queue. This is achieved by using the refcount-aware
rxq_alloc_elts() before overwriting queue data.
