0e78cfddc0 net/virtio: fix crash when closing twice
This commit fixs segment fault when rte_eth_dev_close() is called on
a virtio dev more than once.  Assigning zero after free to avoids
freed memory to be accessed again.

2c2201fb07 net/virtio-user: fix device type check
Segfault happens when using virtio-user after commit 7f0a669e7b
("ethdev: add allocation helper for virtual drivers").

It's due to we use ethdev->device to recognize physical devices,
but after above commit, this field is also filled for virtual
devices. Then we obtain the wrong pci_dev pointer and accessing
its field when copying pci info results in segfault.

To fix it, we use hw->virtio_user_dev to differentiate physical
devices from virtual devices.

Fixes: 6a7c0dfcdf ("net/virtio: do not depend on PCI device of ethdev")

58d9fe4000 net/virtio: fix link status always down
The virtio port link status will always be DOWN:

The commit aa9f060617 ("net/virtio: fix link status always being up")
introduces a flag to help checking the status. If this flag is not set,
status will be always down. However, in dev start, this flag is set
after link status update, then we miss the chance to change the status
to UP in dev start.

To fix this bug, we simply move the link status update after the flag
setting so that the status can be correctly updated.

554b6d3ef9 net/virtio: fix MSI-X for modern devices
The field, use_msix, in struct virtio_hw is not updated for modern
device, and is always zero. And now we depend on the status feature
and MSI-X to report LSC support (which is also not a correct
behavior). As a result, LSC is always disabled for modern devices.

To fix this, we just recognize MSI-X capability when going through
capability list, and update the info in virtio.

c12d22f65b net/ixgbe: ensure link status is updated
In case of fiber and link speed set to 1Gb at peer side (with autoneg
or with defined speed), link status could be not properly updated at
time cable is plugged-in.
Indeed if cable was not plugged when device has been configured and
started then link status will not be updated properly with new speed
as no link setup will be triggered.

To avoid this issue, IXGBE_FLAG_NEED_LINK_CONFIG is set to try a link
setup each time link_update() is triggered and current link status is
down. When cable is plugged-in, link setup will be performed via
ixgbe_setup_link().

aaef1010af net/nfp: fix releasing muti-segment mbufs
If segments are used, just mbufs previously linked to head descriptor
of a mbuf chain are released. Other Tx descriptor are used for the
mbuf chain but they keep their linked mbufs without releasing them.

It is not a fatal issue because sooner or later those descriptors will
be head descriptors or just used for a single mbuf packet, then those
linked mbufs will be released.

However, this leads to apps needing bigger mbufs pools and some
confusion about memory requirements. Indeed, because larger pools, some
performance impact could also be expected due to cache misses.

With this patch all Tx descriptors will release linked mbufs inside the
xmit function, and rte_pktmbuf_seg_free is used instead of
rte_pktmbuf_free.

49d8b54e86 net/qede: fix default MAC address handling
- In qede_mac_addr_set(), in order to configure default MAC address we
first delete the existing MAC address before trying to add new one. During
init time, there is no MAC filter to begin with, so trying to remove a
non-existing MAC address causes a firmware exception. This can be prevented
by internally calling qede_mac_addr_add() which has the checks in place to
delete a MAC address only if it was added before.

- Remove setting of the default MAC address from within
qede_dev_configure() since rte_eth_dev_start() calls mac_addr_set() anyway.

which should not happen for a 32-bit system.

In case of virtio-user, we use buf_addr of mbuf to fill the
virtqueue desc addr. This is a regression bug. For 32-bit system,
the first 4 bytes of mbuf is buf_addr, with following 8 bytes for
buf_phyaddr. With below wrong definition, both buf_addr and lower
4 bytes buf_phyaddr are obtained to fill the virtqueue desc.
  #define VIRTIO_MBUF_ADDR(mb, vq) \
	(*(uint64_t *)((uintptr_t)(mb) + (vq)->offset))

cc4690e980 net/virtio-user: fix link status
Previously, we miss to set intr_handle->fd which will be used as
target file for epoll to check LSC.

As a result, stdin (0) is used and intr thread keeps busy whenever
data comes from stdin.

To fix this, we use vhostfd as the target file for epoll to check
the link status change events. And we move intr_handle initialization
after vhost backend settup to make sure vhostfd is initialized.

aa9f060617 net/virtio: fix link status always being up
The virtio port link status will always be UP, even the port is stopped:

    testpmd> port stop 0
    Stopping ports...
    Checking link statuses...
    Port 0 Link Up - speed 10000 Mbps - full-duplex
    Done

The link status is queried by link_update callback when LSC is disabled.
Which in turn queries the "status" field.  However, the "status" is
read-only. I couldn't think of some proper ways to change the status
without doing device reset.

Instead of doing (the heavy) reset at stop, this patch introduced a flag,
which is set to 1 and 0 on start and stop, respectively. When it's set to
0, the link status is set to DOWN unconditionally.

4bf9e26d29 net/virtio-user: fix net status report
We only enabled LSC when using vhost-user as the backend, but it is
reported even when using vhost-kernel as the backend.

Fix it by only reportting LSC support when using vhost-user as the
backend.

bed3b24c87 net/virtio-user: fix feature negotiation
The feature negotiation in virtio-user is proven to be broken,
which results in device initialization failure.

Originally, we get features from vhost backend, and remove those
that are not supported. But when new feature is added, for example,
VIRTIO_NET_F_MTU, we fail to remove this new feature. Then, this
new feature will be negotiated, as both frontend and backend claim
to support this feature.

To fix it, we add a macro to record supported features, as a filter
to remove newly added features.

912be9daf4 net/vhost: stop dev in close and address mem leak
Move the call to stop the device inside the close routine because close
needs to stop the device if it isn't stopped.

Free the allocated queue buffers in close instead of doing so in remove.
Original code had these clean ups in remove which was causing memory
leak.

518208f3a1 net/virtio: fix queue notify
According to spec, we should write virtqueue index into the notify
address, rather than 1. Besides, some HW backend may rely on the data
written to identify which queue need to serve.
