This commit implements features provisioning for ifcvf, that means: 1)checkk whether the provisioned features are supported by the management device 2)vDPA device only presents selected feature bits Examples: a)The management device supported features: $ vdpa mgmtdev show pci/0000:01:00.5 pci/0000:01:00.5: supported_classes net max_supported_vqs 9 dev_features MTU MAC MRG_RXBUF CTRL_VQ MQ ANY_LAYOUT VERSION_1 ACCESS_PLATFORM b)Provision a vDPA device with all supported features: $ vdpa dev add name vdpa0 mgmtdev pci/0000:01:00.5 $ vdpa/vdpa dev config show vdpa0 vdpa0: mac 00:e8:ca:11:be:05 link up link_announce false max_vq_pairs 4 mtu 1500 negotiated_features MRG_RXBUF CTRL_VQ MQ VERSION_1 ACCESS_PLATFORM c)Provision a vDPA device with a subset of the supported features: $ vdpa dev add name vdpa0 mgmtdev pci/0000:01:00.5 device_features 0x300020020 $ vdpa dev config show vdpa0 mac 00:e8:ca:11:be:05 link up link_announce false negotiated_features CTRL_VQ VERSION_1 ACCESS_PLATFORM Signed-off-by: Zhu Lingshan <lingshan.zhu@intel.com> Message-Id: <20221125145724.1129962-13-lingshan.zhu@intel.com> Signed-off-by: Michael S.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
