The netdev reports NETDEV_STREAM_CONNECTED event when the backend
is connected, and NETDEV_STREAM_DISCONNECTED when it is disconnected.
The NETDEV_STREAM_CONNECTED event includes the destination address.
This allows a system manager like libvirt to detect when the server
fails.
For instance with passt:
{ 'execute': 'qmp_capabilities' }
{ "return": { } }

To be consistent with socket_uri(), add 'tcp:' prefix for inet type in
socket_parse(), by default socket_parse() use tcp when no prefix is
provided (format is host:port).
In socket_uri(), use 'vsock:' prefix for vsock type rather than 'tcp:'
because it makes a vsock address look like an inet address with CID
misinterpreted as host.

Copied from socket netdev file and modified to use SocketAddress
to be able to introduce new features like unix socket.
"udp" and "mcast" are squashed into dgram netdev, multicast is detected
according to the IP address type.
"listen" and "connect" modes are managed by stream netdev. An optional
parameter "server" defines the mode (off by default)
The two new types need to be parsed the modern way with -netdev, because
with the traditional way, the "type" field of netdev structure collides with
the "type" field of SocketAddress and prevents the correct evaluation of the
command line option. Moreover the traditional way doesn't allow to use
the same type (SocketAddress) several times with the -netdev option
(needed to specify "local" and "remote" addresses).
The previous commit paved the way for parsing the modern way, but
omitted one detail: how to pick modern vs. traditional, in
netdev_is_modern().
We want to pick based on the value of parameter "type". But how to
extract it from the option argument?
Parsing the option argument, either the modern or the traditional way,
extracts it for us, but only if parsing succeeds.
If parsing fails, there is no good option. No matter which parser we
pick, it'll be the wrong one for some arguments, and the error
reporting will be confusing.
Fortunately, the traditional parser accepts *anything* when called in
a certain way. This maximizes our chance to extract the value of
"type", and in turn minimizes the risk of confusing error reporting.

As qemu_opts_parse_noisily() flattens the QAPI structures ("type" field
of Netdev structure can collides with "type" field of SocketAddress),
we introduce a way to bypass qemu_opts_parse_noisily() and use directly
visit_type_Netdev() to parse the backend parameters.
More details from Markus:
qemu_init() passes the argument of -netdev, -nic, and -net to
net_client_parse().
net_client_parse() parses with qemu_opts_parse_noisily(), passing
QemuOptsList qemu_netdev_opts for -netdev, qemu_nic_opts for -nic, and
qemu_net_opts for -net. Their desc[] are all empty, which means any
keys are accepted. The result of the parse (a QemuOpts) is stored in
the QemuOptsList.
Note that QemuOpts is flat by design. In some places, we layer non-flat
on top using dotted keys convention, but not here.
net_init_clients() iterates over the stored QemuOpts, and passes them to
net_init_netdev(), net_param_nic(), or net_init_client(), respectively.
These functions pass the QemuOpts to net_client_init(). They also do
other things with the QemuOpts, which we can ignore here.
net_client_init() uses the opts visitor to convert the (flat) QemOpts to
a (non-flat) QAPI object Netdev. Netdev is also the argument of QMP
command netdev_add.
The opts visitor was an early attempt to support QAPI in
(QemuOpts-based) CLI. It restricts QAPI types to a certain shape; see
commit eb7ee2cbeb "qapi: introduce OptsVisitor".
A more modern way to support QAPI is qobject_input_visitor_new_str().
It uses keyval_parse() instead of QemuOpts for KEY=VALUE,... syntax, and
it also supports JSON syntax. The former isn't quite as expressive as
JSON, but it's a lot closer than QemuOpts + opts visitor.
This commit paves the way to use of the modern way instead.

The current message when using '-net user...' with SLIRP disabled at
compile time is:
qemu-system-x86_64: -net user: Parameter 'type' expects a net backend type (maybe it is not compiled into this binary)
An observation is that we're using the 'netdev->type' field here which
is an enum value, produced after QAPI has converted from its string
form.
IOW, at this point in the code, we know that the user's specified
type name was a valid network backend. The only possible scenario that
can make the backend init function be NULL, is if support for that
backend was disabled at build time. Given this, we don't need to caveat
our error message with a 'maybe' hint, we can be totally explicit.
The use of QERR_INVALID_PARAMETER_VALUE doesn't really lend itself to
user friendly error message text. Since this is not used to set a
specific QAPI error class, we can simply stop using this pre-formatted
error text and provide something better.
Thus the new message is:
qemu-system-x86_64: -net user: network backend 'user' is not compiled into this binary
The case of passing 'hubport' for -net is also given a message reminding
people they should have used -netdev/-nic instead, as this backend type
is only valid for the modern syntax.

When virtio-net is used with the socket netdev backend, the backend
can be busy and not able to collect new packets.
In this case, net_socket_receive() returns 0 and registers a poll function
to detect when the socket is ready again.
In virtio_net_tx_bh(), virtio_net_flush_tx() forwards the 0, the virtio
notifications are disabled and the function is not re-scheduled, waiting
for the backend to be ready.
When the socket netdev backend is again able to send packets, the poll
function re-starts to flush remaining packets. This is done by
calling virtio_net_tx_complete(). It re-enables notifications and calls
again virtio_net_flush_tx().
But it seems if virtio_net_flush_tx() reaches the tx_burst value all
the queue is not flushed and no new notification is sent to re-schedule
virtio_net_tx_bh(). Nothing re-start to flush the queue and remaining
packets are stuck in the queue.
To fix that, detect in virtio_net_tx_complete() if virtio_net_flush_tx()
has been stopped by tx_burst and if yes re-schedule the bottom half
function virtio_net_tx_bh() to flush the remaining packets.
This is what is done in virtio_net_tx_bh() when the virtio_net_flush_tx()
is synchronous, and completly by-passed when the operation needs to be
asynchronous.
