The configuration/command below is failing when the VF in the xml file is already bound to the host iavf driver. pci_0000_af_0_0.xml: <interface type='hostdev' managed='yes'> <source> <address type='pci' domain='0x0000' bus='0xaf' slot='0x0' function='0x0'/> </source> <mac address='00🇩🇪ad:00:11:01'/> </interface> > virsh attach-device domain_name pci_0000_af_0_0.xml error: Failed to attach device from pci_0000_af_0_0.xml error: Cannot set interface MAC/vlanid to 00🇩🇪ad:00:11:01/0 for ifname ens1f1 vf 0: Device or resource busy This is failing because the VF has not been completely removed/reset after being unbound (via the virsh command above) from the host iavf driver and ice_set_vf_mac() checks if the VF is disabled before waiting for the reset to finish. Fix this by waiting for the VF remove/reset process to happen before checking if the VF is disabled. Also, since many functions for VF administration on the PF were more or less calling the same 3 functions (ice_wait_on_vf_reset(), ice_is_vf_disabled(), and ice_check_vf_init()) move these into the helper function ice_check_vf_ready_for_cfg(). Then call this function in any flow that attempts to configure/query a VF from the PF. Lastly, increase the maximum wait time in ice_wait_on_vf_reset() to 800ms, and modify/add the #define(s) that determine the wait time. This was done for robustness because in rare/stress cases VF removal can take a max of ~800ms and previously the wait was a max of ~300ms.

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.
