It's time to remove the deprecated "name" parameter from -net.
Please have a closer look at the second patch ... I think it should be
fine, but I'm not 100% sure whether it's ok for all cases to drop NetLegacy,
so please double-check.

New subject: [libvirt] [PATCH 1/2] net: Drop the legacy "name" parameter from the -net option
It's been deprecated since QEMU v3.1, so it's time to finally
remove it. The "id" parameter can simply be used instead.

We should either do this systematically, or not at all. If the former,
we have quite a few "dropped in" to add belatedly.

We should either do this systematically, or not at all. If the former,
we have quite a few "dropped in" to add belatedly.
IIRC this has been suggested by Eric, see e.g.:
https://patchwork.kernel.org/patch/10227335/#21501161
Anyway, it should not matter much for this patch here, since the line
gets removed again in the 2nd patch anyway.

Comparing this to the branches of Netdev:
We are losing 'none', while gaining 'hubport'. The gain is not
problematic, and I guess you are declaring that the use of 'none' has
been deprecated long enough to not be a problem.

when deleting 'name' (after all, id was optional only when name was in
use)?
No, since "id" is still not mandatory for "-net". In case it is
missing,
the code creates an id internally (see assign_name() in net/net.c).

been deprecated long enough to not be a problem.
'none' still continues to work, it's also a member of NetClientDriver
and was handled later in the patch:
+ if (netdev->type == NET_CLIENT_DRIVER_NONE) {
return 0; /* nothing to do */
'hubport' is blocked in the code now instead:
+ if (netdev->type == NET_CLIENT_DRIVER_HUBPORT ||
+ !net_client_init_fun[netdev->type]) {
error_setg(errp, QERR_INVALID_PARAMETER_VALUE, "type",
"a net backend type (maybe it is not compiled "
"into this binary)");

Should we rename this to NetdevNicOptions, now that we are getting rid
of other NetLegacy names?
I still consider "-net nic" as a legacy option that we should remove one
day in the future, so I'd rather keep that name.
But I concur that all branches of the Netdev union have the same types
as what you are removing here from NetLegacyOptions, so the
consolidation looks sane.
Ok, thanks for your review!

New subject: [libvirt] [PATCH 2/2] net: Drop the NetLegacy structure, always use Netdev instead
Thomas Huth <thuth(a)redhat.com> writes:
Now that the "name" parameter is gone, there is hardly any
difference
between NetLegacy and Netdev anymore. Drop NetLegacy and always use
Netdev to simplify the code quite a bit.

Took me a minute to see the actual difference.
Here's Netdev:
{ 'union': 'Netdev',
'base': { 'id': 'str', 'type':
'NetClientDriver' },
'discriminator': 'type',
'data': {
'nic': 'NetLegacyNicOptions',
'user': 'NetdevUserOptions',
'tap': 'NetdevTapOptions',
'l2tpv3': 'NetdevL2TPv3Options',
'socket': 'NetdevSocketOptions',
'vde': 'NetdevVdeOptions',
'bridge': 'NetdevBridgeOptions',
'hubport': 'NetdevHubPortOptions',
'netmap': 'NetdevNetmapOptions',
'vhost-user': 'NetdevVhostUserOptions' } }
{ 'enum': 'NetClientDriver',
'data': [ 'none', 'nic', 'user', 'tap',
'l2tpv3', 'socket', 'vde',
'bridge', 'hubport', 'netmap',
'vhost-user' ] }
Here's NetLegacy:
{ 'struct': 'NetLegacy',
'data': {
'*id': 'str',
'opts': 'NetLegacyOptions' } }
{ 'union': 'NetLegacyOptions',
'base': { 'type': 'NetLegacyOptionsType' },
'discriminator': 'type',
'data': {
'nic': 'NetLegacyNicOptions',
'user': 'NetdevUserOptions',
'tap': 'NetdevTapOptions',
'l2tpv3': 'NetdevL2TPv3Options',
'socket': 'NetdevSocketOptions',
'vde': 'NetdevVdeOptions',
'bridge': 'NetdevBridgeOptions',
'netmap': 'NetdevNetmapOptions',
'vhost-user': 'NetdevVhostUserOptions' } }
{ 'enum': 'NetLegacyOptionsType',
'data': ['none', 'nic', 'user', 'tap',
'l2tpv3', 'socket', 'vde',
'bridge', 'netmap', 'vhost-user'] }
Difference: NetLegacy wraps the union in @opts.
