4d6cf2ac93 net/vhost: add extended statistics
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.

2304dd73d2 vhost: support indirect Tx descriptors
Indirect descriptors are usually supported by virtio-net devices,
allowing to dispatch a larger number of requests.

When the virtio device sends a packet using indirect descriptors,
only one slot is used in the ring, even for large packets.

The main effect is to improve the 0% packet loss benchmark.
A PVP benchmark using Moongen (64 bytes) on the TE, and testpmd
(fwd io for host, macswap for VM) on DUT shows a +50% gain for
zero loss.

On the downside, micro-benchmark using testpmd txonly in VM and
rxonly on host shows a loss between 1 and 4%. But depending on
the needs, feature can be disabled at VM boot time by passing
indirect_desc=off argument to vhost-user device in Qemu.

c711ccb309 ivshmem: remove library and its EAL integration
Following discussions on the mailing list [1] and since nobody stood up to
implement the necessary cleanups, here is the ivshmem integration removal.

There is not much to say about this patch, a lot of code is being removed.
The default configuration file for packet_ordering example is replaced with
the "native" x86 file.
The only tricky part is in eal_memory with the memseg index stuff.

More cleanups can be done after this but will come in subsequent patchsets.

9db3f52126 doc: generate NIC overview table from ini files
Convert the NIC feature table in the overview doc into a set of ini
files and add functions into the Sphinx conf.py file to auto-generate
them back into an RST table.

The reason for doing this is to make it easier for PMD maintainers to
update the feature matrix that makes up the table and to avoid
frequent and hard to resolve conflicts in doc/guides/nics/overview.rst.

A NIC/PMD feature matrix is now an ini file like the following:

    $ head doc/guides/nics/nic_features/i40e.ini
    ;
    ; Features of the i40e network driver.
    ;
    [Features]
    Link status          = Y
    Link status event    = Y
    Rx interrupt         = Y
    Queue start/stop     = Y
    ...

The output RST table matches the existing table with the column
headers sorted.

8a3433af84 doc: announce vhost-cuse removal
Vhost-cuse was invented before vhost-user exist. The both are actually
doing the same thing: a vhost-net implementation in user space. But they
are not exactly the same thing.

Firstly, vhost-cuse is harder for use; no one seems to care it, either.
Furthermore, since v2.1, a large majority of development effort has gone
to vhost-user. For example, we extended the vhost-user spec to add the
multiple queue support. We also added the vhost-user live migration at
v16.04 and the latest one, vhost-user reconnect that allows vhost app
restart without restarting the guest. Both of them are very important
features for product usage and none of them works for vhost-cuse.

You now see that the difference between vhost-user and vhost-cuse is
big (and will be bigger and bigger as time moves forward), that you
should never use vhost-cuse, that we should drop it completely.

The remove would also result to a much cleaner code base, allowing us
to do all kinds of extending easier.

So here to mark vhost-cuse as deprecated in this release and will be
removed in the next release (v16.11).

ad5fd43ba1 doc: announce ABI change for Tx preparation
This is an ABI deprecation notice for DPDK 16.11 in librte_ether about
changes in rte_eth_dev and rte_eth_desc_lim structures.

As discussed in that thread:

http://dpdk.org/ml/archives/dev/2015-September/023603.html

Different NIC models depending on HW offload requested might impose
different requirements on packets to be TX-ed in terms of:

 - Max number of fragments per packet allowed
 - Max number of fragments per TSO segments
 - The way pseudo-header checksum should be pre-calculated
 - L3/L4 header fields filling
 - etc.

MOTIVATION:
-----------

1) Some work cannot (and didn't should) be done in rte_eth_tx_burst.
   However, this work is sometimes required, and now, it's an
   application issue.

2) Different hardware may have different requirements for TX offloads,
   other subset can be supported and so on.

3) Some parameters (eg. number of segments in ixgbe driver) may hung
   device. These parameters may be vary for different devices.

   For example i40e HW allows 8 fragments per packet, but that is after
   TSO segmentation. While ixgbe has a 38-fragment pre-TSO limit.

4) Fields in packet may require different initialization (like eg. will
   require pseudo-header checksum precalculation, sometimes in a
   different way depending on packet type, and so on). Now application
   needs to care about it.

5) Using additional API (rte_eth_tx_prep) before rte_eth_tx_burst let to
   prepare packet burst in acceptable form for specific device.

6) Some additional checks may be done in debug mode keeping tx_burst
   implementation clean.

PROPOSAL:
---------

To help user to deal with all these varieties we propose to:

1. Introduce rte_eth_tx_prep() function to do necessary preparations of
   packet burst to be safely transmitted on device for desired HW
   offloads (set/reset checksum field according to the hardware
   requirements) and check HW constraints (number of segments per
   packet, etc).

   While the limitations and requirements may differ for devices, it
   requires to extend rte_eth_dev structure with new function pointer
   "tx_pkt_prep" which can be implemented in the driver to prepare and
   verify packets, in devices specific way, before burst, what should to
   prevent application to send malformed packets.

2. Also new fields will be introduced in rte_eth_desc_lim:
   nb_seg_max and nb_mtu_seg_max, providing an information about max
   segments in TSO and non-TSO packets acceptable by device.

   This information is useful for application to not create/limit
   malicious packet.

APPLICATION (CASE OF USE):
--------------------------

1) Application should to initialize burst of packets to send, set
   required tx offload flags and required fields, like l2_len, l3_len,
   l4_len, and tso_segsz

2) Application passes burst to the rte_eth_tx_prep to check conditions
   required to send packets through the NIC.

3) The result of rte_eth_tx_prep can be used to send valid packets
   and/or restore invalid if function fails.

eg.

	for (i = 0; i < nb_pkts; i++) {

		/* initialize or process packet */

		bufs[i]->tso_segsz = 800;
		bufs[i]->ol_flags = PKT_TX_TCP_SEG | PKT_TX_IPV4
				| PKT_TX_IP_CKSUM;
		bufs[i]->l2_len = sizeof(struct ether_hdr);
		bufs[i]->l3_len = sizeof(struct ipv4_hdr);
		bufs[i]->l4_len = sizeof(struct tcp_hdr);
	}

	/* Prepare burst of TX packets */
	nb_prep = rte_eth_tx_prep(port, 0, bufs, nb_pkts);

	if (nb_prep < nb_pkts) {
		printf("tx_prep failed\n");

		/* drop or restore invalid packets */

	}

	/* Send burst of TX packets */
	nb_tx = rte_eth_tx_burst(port, 0, bufs, nb_prep);

	/* Free any unsent packets. */

The right name of ethdev should be dpdk_netdev. However:
1/ We are using rte_ prefix in the code and library names.
2/ The API uses rte_ethdev
That's why 16.11 will just have the rte_ prefix prepended to
the library filename as every other libraries.

a5d7a3f77d unify tools naming
The following tools may be installed system-wide.
It may be cleaner and more convenient to find them with the same
dpdk- prefix (especially for autocompletion).
Moreover, the script dpdk_nic_bind.py deserves a new name because it is
not restricted to NICs and can be used for e.g. crypto.

These files are renamed:
pmdinfogen       -> dpdk-pmdinfogen
pmdinfo.py       -> dpdk-pmdinfo.py
dpdk_pdump       -> dpdk-pdump
dpdk_proc_info   -> dpdk-procinfo
dpdk_nic_bind.py -> dpdk-devbind.py
setup.sh         -> dpdk-setup.sh

The tools pmdinfogen, pmdinfo.py and dpdk_pdump are new in 16.07.

The scripts dpdk_nic_bind.py and setup.sh may have been used with
previous releases by end users. That's why a symbolic link still
provide the old name in the installed tools directory.

f6ee75b542 doc: note a pitfall on vhost reconnect feature
The vhost feature negotiation only happens at virtio reset stage, say
when a virtio-net device is firstly initiated, or when DPDK virtio PMD
initiates. That means, if vhost APP restarts after the negotiation and
reconnects, the feature negotiation process will not be triggered again,
meaning the info is lost. To make reconnect work, QEMU simply saves
the negotiated features before the restart and restores it afterwards.

Therefore, the vhost supported features must be exactly the same before
and after the restart. For example, if TSO is disabled and then enabled,
nothing will work and undefined issues might happen.

d05aafe62f igb_uio: fix possible mmap failure with Linux 4.5

EAL: pci_map_resource():

CONFIG_IO_STRICT_DEVMEM is introduced in Linux v4.5 and not enabled
by default:
Linux commit: 90a545e restrict /dev/mem to idle io memory ranges

As a workaround igb_uio can stop reserving PCI memory resources, from
kernel point of view iomem region looks like idle and mmap works
again. This matches uio_pci_generic usage.

With this update device iomem range is not protected against any
other kernel drivers or userspace access. But this  shouldn't
be a problem for dpdk usage module since purpose of the igb_uio
module is to provide userspace access.

a0fd91cefc mempool: rename functions with confusing names
The mempool_count and mempool_free_count behaved contrary to what their
names suggested. The free_count function actually returned the number of
elements that were allocated from the pool, not the number unallocated as
the name implied.

Fix this by introducing two new functions to replace the old ones,
* rte_mempool_avail_count to replace rte_mempool_count
* rte_mempool_in_use_count to replace rte_mempool_free_count

In this patch, the new functions are added, and the old ones are marked
as deprecated. All apps and examples that use the old functions are
updated to use the new functions.

79f2248219 net/i40e: add floating VEB option
The standard Virtual Ethernet Bridge(VEB) definition in 1Qbg is a bridge
which has an uplink port to the outside world (maybe another 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 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.

99c12dcca6 net/mlx5: handle Rx CQE compression
Mini (compressed) completion queue entries (CQEs) are returned by the
NIC when PCI back pressure is detected, in which case the first CQE64
contains common packet information followed by a number of CQE8
providing the rest, followed by a matching number of empty CQE64
entries to be used by software for decompression.

Before decompression:

      0           1          2           6         7         8
  +-------+  +---------+ +-------+   +-------+ +-------+ +-------+
  | CQE64 |  |  CQE64  | | CQE64 |   | CQE64 | | CQE64 | | CQE64 |
  |-------|  |---------| |-------|   |-------| |-------| |-------|
  | ..... |  | cqe8[0] | |       | . |       | |       | | ..... |
  | ..... |  | cqe8[1] | |       | . |       | |       | | ..... |
  | ..... |  | ....... | |       | . |       | |       | | ..... |
  | ..... |  | cqe8[7] | |       |   |       | |       | | ..... |
  +-------+  +---------+ +-------+   +-------+ +-------+ +-------+

After decompression:

      0          1     ...     8
  +-------+  +-------+     +-------+
  | CQE64 |  | CQE64 |     | CQE64 |
  |-------|  |-------|     |-------|
  | ..... |  | ..... |  .  | ..... |
  | ..... |  | ..... |  .  | ..... |
  | ..... |  | ..... |  .  | ..... |
  | ..... |  | ..... |     | ..... |
  +-------+  +-------+     +-------+

This patch does not perform the entire decompression step as it would be
really expensive, instead the first CQE64 is consumed and an internal
context is maintained to interpret the following CQE8 entries directly.

Intermediate empty CQE64 entries are handed back to HW without further
processing.

856d7ba7ed net/enic: support scattered Rx
For performance reasons, this patch uses 2 VIC RQs per RQ presented to
DPDK.

The VIC requires that each descriptor be marked as either a start of
packet (SOP) descriptor or a non-SOP descriptor.  A one RQ solution
requires skipping descriptors when receiving small packets and results
in bad performance when receiving many small packets.

The 2 RQ solution makes use of the VIC feature that allows a receive
on primary queue to 'spill over' into another queue if the receive is
too large to fit in the buffer assigned to the descriptor on the
primary queue.  This means that there is no skipping of descriptors
when receiving small packets and results in much better performance.

ca7e599d45 net/i40e: fix link management
Previously, there was a known issue "On Intel® 40G Ethernet
Controller stopping the port does not really down the port link."

There were two reasons why the port was always kept up.
1. Old firmware versions had issues when "Set PHY config command"
   was used on 40G NICs.
2. The kernel i40e driver didn't call "Set PHY config command" when
   ifconfig up/down was used, it assumes the link is always up. But
   in DPDK, ports are forced down when an applications quits. So if
   the port is then switched to being controlled by kernel the driver,
   the port can not be brought up through "ifconfig <ethx> up".

This patch fixes this issue by adding in "Set PHY config command"
into our driver. This is now possible because with newer firmware
there is no longer a problem using this command.

With this fix, after DPDK quit, if the port is switched to being used
by the kernel driver, "ethtool -s <ethx> autoneg on" can be used to
turn on the auto negotiation, and then port can be brought up through
"ifconfig <ethx> up".
NOTE: requires kernel i40e driver version >= 1.4.X

be856325cb hash: add scalable multi-writer insertion with Intel TSX
This patch introduced scalable multi-writer Cuckoo Hash insertion
based on a split Cuckoo Search and Move operation using Intel
TSX. It can do scalable hash insertion with 22 cores with little
performance loss and negligible TSX abortion rate.

* Added an extra rte_hash flag definition to switch default single writer
  Cuckoo Hash behavior to multiwriter.
    - If HTM is available, it would use hardware feature for concurrency.
    - If HTM is not available, it would fall back to spinlock.

* Created a rte_cuckoo_hash_x86.h file to hold all x86-arch related
  cuckoo_hash functions. And rte_cuckoo_hash.c uses compile time flag to
  select x86 file or other platform-specific implementations. While HTM check
  is still done at runtime (same idea with
  RTE_HASH_EXTRA_FLAGS_TRANS_MEM_SUPPORT)

* Moved rte_hash private struct definitions to rte_cuckoo_hash.h, to allow
  rte_cuckoo_hash_x86.h or future platform dependent functions to include.

* Following new functions are created for consistent names when new platform
  TM support are added.
    - rte_hash_cuckoo_move_insert_mw_tm: do insertion with bucket movement.
    - rte_hash_cuckoo_insert_mw_tm: do insertion without bucket movement.

* One extra multi-writer test case is added.

ce2eabdd43 net/virtio-user: add virtual device
Add a new virtual device named virtio-user, which can be used just like
eth_ring, eth_null, etc. To reuse the code of original virtio, we do
some adjustment in virtio_ethdev.c, such as remove key _static_ of
eth_virtio_dev_init() so that it can be reused in virtual device; and
we add some check to make sure it will not crash.

Configured parameters include:
  - queues (optional, 1 by default), number of queue pairs, multi-queue
    not supported for now.
  - cq (optional, 0 by default), not supported for now.
  - mac (optional), random value will be given if not specified.
  - queue_size (optional, 256 by default), size of virtqueues.
  - path (madatory), path of vhost user.

When enable CONFIG_RTE_VIRTIO_USER (enabled by default), the compiled
library can be used in both VM and container environment.

Examples:
path_vhost=<path_to_vhost_user> # use vhost-user as a backend

sudo ./examples/l2fwd/build/l2fwd -c 0x100000 -n 4 \
    --socket-mem 0,1024 --no-pci --file-prefix=l2fwd \
    --vdev=virtio-user0,mac=00:01:02:03:04:05,path=$path_vhost -- -p 0x1

Known issues:
 - Control queue and multi-queue are not supported yet.
 - Cannot work with --huge-unlink.
 - Cannot work with no-huge.
 - Cannot work when there are more than VHOST_MEMORY_MAX_NREGIONS(8)
   hugepages.
 - Root privilege is a must (mainly becase of sorting hugepages according
   to physical address).
 - Applications should not use file name like HUGEFILE_FMT ("%smap_%d").

39449e7429 vhost: remove concurrent enqueue
All other DPDK PMDs doesn't support concurrent receiving or sending
packets to the same queue. The upper application should deal with
this, normally through queue and core bindings.

Due to historical reason, vhost internally supports concurrent lockless
enqueuing packets to the same virtio queue through costly cmpset operation.
This patch removes this internal lockless implementation and should improve
performance a bit.

Luckily DPDK OVS doesn't rely on this behavior.

caa7028276 app/pdump: add tool for packet capturing
The new pdump tool is added for packet capturing on dpdk.
This tool runs as secondary process by default.
Tool facilitates the command line options like
port, device_id, queue which user should pass on
to the tool to request the packet capture on those devices.

Tool creates the rte ring, mempool and pcap vdev and
calls the enable API of the pdump library with port/device_id,
queue, ring and mempool as arguments to enable the packet
capture on specific devices and gets the packets from the
primary process over the ring. Once the packets are
received, those packets will be send to the pcap vdev.

Tool can be terminated by using ctrl+c(SIGINT) upon which tool
calls the disable API of the pdump library to disable the packet capture
and dequeues the rest of the packets from the ring and sends them on
to the pcap vdev, then after releases all allocated resources.

278f945402 pdump: add new library for packet capture
The librte_pdump library provides a framework for
packet capturing in dpdk. The library provides set of
APIs to initialize the packet capture framework, to
enable or disable the packet capture, and to uninitialize
it.

The librte_pdump library works on a client/server model.
The server is responsible for enabling or disabling the
packet capture and the clients are responsible
for requesting the enabling or disabling of the packet
capture.

Enabling APIs are supported with port, queue, ring and
mempool parameters. Applications should pass on this information
to get the packets from the dpdk ports.

For enabling requests from applications, library creates the client
request containing the mempool, ring, port and queue information and
sends the request to the server. After receiving the request, server
registers the Rx and Tx callbacks for all the port and queues.
After the callbacks registration, registered callbacks will get the
Rx and Tx packets. Packets then will be copied to the new mbufs that
are allocated from the user passed mempool. These new mbufs then will
be enqueued to the application passed ring. Applications need to dequeue
the mbufs from the rings and direct them to the devices like
pcap vdev for viewing the packets outside of the dpdk
using the packet capture tools.

For disabling requests, library creates the client request containing
the port and queue information and sends the request to the server.
After receiving the request, server removes the Rx and Tx callback
for all the port and queues.

00851d47f7 ethdev: get queues numbers
The new fields nb_rx_queues and nb_tx_queues are added to the
rte_eth_dev_info structure.
Changes to API rte_eth_dev_info_get() are done to update these new fields
to the rte_eth_dev_info object.
Release notes is updated with the changes.

The librte_pdump library needs to register Rx and Tx callbacks for all
the nb_rx_queues and nb_tx_queues, when application wants to capture the
packets on all the software configured number of Rx and Tx queues of the
device. So far there is no support to get nb_rx_queues and nb_tx_queues
information from the ethdev library. Hence these changes are introduced.

b37b528d95 mbuf: add new Rx flags for stripped VLAN
The behavior of PKT_RX_VLAN_PKT was not very well defined, resulting in
PMDs not advertising the same flags in similar conditions.

Following discussion in [1], introduce 2 new flags PKT_RX_VLAN_STRIPPED
and PKT_RX_QINQ_STRIPPED that are better defined:

  PKT_RX_VLAN_STRIPPED: a vlan has been stripped by the hardware and its
  tci is saved in mbuf->vlan_tci. This can only happen if vlan stripping
  is enabled in the RX configuration of the PMD.

For now, the old flag PKT_RX_VLAN_PKT is kept but marked as deprecated.
It should be removed from applications and PMDs in a future revision.

This patch also updates the drivers. For PKT_RX_VLAN_PKT:

- e1000, enic, i40e, mlx5, nfp, vmxnet3: done, PKT_RX_VLAN_PKT already
  had the same meaning than PKT_RX_VLAN_STRIPPED, minor update is
  required.
- fm10k: done, PKT_RX_VLAN_PKT already had the same meaning than
  PKT_RX_VLAN_STRIPPED, and vlan stripping is always enabled on fm10k.
- ixgbe: modification done (vector and normal), the old flag was set
  when a vlan was recognized, even if vlan stripping was disabled.
- the other drivers do not support vlan stripping.

For PKT_RX_QINQ_PKT, it was only supported on i40e, and the behavior was
already correct, so we can reuse the same bit value for
PKT_RX_QINQ_STRIPPED.

50705e8e3c eal: add assert macro for debug
The macro RTE_VERIFY always checks a condition.
It is optimized with "unlikely" hint.
While this macro is well suited for test applications, it is preferred
in libraries and examples to enable such check in debug mode.
That's why the macro RTE_ASSERT is introduced to call RTE_VERIFY only
if built with debug logs enabled.

A lot of assert macros were duplicated and enabled with a specific flag.
Removing these #ifdef allows to test these code branches more easily
and avoid dead code pitfalls.

The ENA_ASSERT is kept (in debug mode only) because it has more
parameters to log.

9b9d7caa84 log: increase default level to info
The default was to compile every logs (including debug) and set
the default level to debug.
As some debug logs may hurt performance, a notice is added and the
default level is now info.

In order to enable debug logs, they must be compiled with
RTE_LOG_LEVEL=RTE_LOG_DEBUG and enabled at runtime with --log-level=8.

d9ba0b2c5a doc: improve nics features matrix
Changed symbol on NIC overview table from X to Y to help

confusion for some readers.

Also, added * character to indicate partially supported
features. This can be used in the future to direct the reader
to more specific details in the individual NIC guides.

Some statistics were deprecated since release 2.1 (49f386542a).
The last deprecated counter to be used was imcasts.

The VF loopback statistics are also removed as they are used only
in igb and duplicated in extended statistics.

The new counters should be added to extended statistics.

The driver i40e was using a specific PCI config before the release 16.04.
Since 16.04, it is always enabled in i40e (commit 56465cfaf).
The API has been deprecated in the commit 68f7759382.
The igb_uio implementation has been deprecated in commit b7cf8e155.
The config helper - through igb_uio sysfs entries - is now removed.

edbeb7d962 scripts: check commit formatting
The git messages have three parts:
1/ the headline
2/ the explanations
3/ the footer tags

The headline helps to quickly browse an history or catch instantly the
purpose of a commit. Making it short with some consistent wording
allows to easily parse it or match some patterns.

The explanations must give some keys like the reason of the change.
Nothing can be automatically checked for this part, except line length.

The footer contains some tags to find the origin of a bug or who
was working on it.

This script is doing some basic checks mostly on parts 1 and 3.

f4f136c8c4 doc: announce API changes for vhost refactoring
We currently exposed way too many fields (or even structures) than
necessary. For example, vhost_virtqueue struct should NOT be exposed
to user at all: application just need to tell the right queue id to
locate a specific queue, and that's all. Instead, the structure should
be defined in an internal header file. With that, we could do any changes
to it we want, without worrying about that we may offense the painful
ABI rules.

Similar changes could be done to virtio_net struct as well, just exposing
very few fields that are necessary and moving all others to an internal
structure.

Huawei then suggested a more radical yet much cleaner one: just exposing
a virtio_net handle to application, just like the way kernel exposes an
fd to user for locating a specific file, and exposing some new functions
to access those old fields, such as flags, virt_qp_nb.

With this change, we're likely to be free from ABI violations forever
(well, except when we have to extend the virtio_net_device_ops struct).
For example, following nice cleanup would not be a blocking one then:
