vdpa: Enable user to query vdpa device config layout
Query the device configuration layout whenever kernel supports it.
An example of configuration layout of vdpa device of type network:
$ vdpa dev add name bar mgmtdev vdpasim_net
$ vdpa dev config show
bar: mac 00:35:09:19:48:05 link up link_announce false mtu 1500
$ vdpa dev config show -jp
{
"config": {
"bar": {
"mac": "00:35:09:19:48:05",
"link ": "up",
"link_announce ": false,
"mtu": 1500,
}
}

Subject: [PATCH] vdpa: Enable user to set mtu of the vdpa device
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2036880
Upstream Status: iproute2.git commit 167e33f3
commit 167e33f3be88c0fbe206df25145b850ddf3897a2
Author: Parav Pandit <parav@nvidia.com>
Date: Fri Dec 17 10:08:27 2021 +0200
vdpa: Enable user to set mtu of the vdpa device
Implement mtu setting for vdpa device.
$ vdpa mgmtdev show
vdpasim_net:
supported_classes net
Add the device with mac address and mtu:
$ vdpa dev add name bar mgmtdev vdpasim_net mac 00:11:22:33:44:55 mtu 9000
In above command only mac address or only mtu can also be set.
View the config after setting:
$ vdpa dev config show
bar: mac 00:11:22:33:44:55 link up link_announce false mtu 9000
