During stress tests with adding VF to namespace and changing vf's trust there was a race between iavf_reset_task and iavf_close. Sometimes when IAVF_FLAG_AQ_DISABLE_QUEUES from iavf_close was sent to PF after reset and before IAVF_AQ_GET_CONFIG was sent then PF returns error IAVF_NOT_SUPPORTED to disable queues request and following requests. There is need to get_config before other aq_required will be send but iavf_close clears all flags, if get_config was not sent before iavf_close, then it will not be send at all. In case when IAVF_FLAG_AQ_GET_OFFLOAD_VLAN_V2_CAPS was sent before IAVF_FLAG_AQ_DISABLE_QUEUES then there was rtnl_lock deadlock between iavf_close and iavf_adminq_task until iavf_close timeouts and disable queues was sent after iavf_close ends. There was also a problem with sending delete/add filters. Sometimes when filters was not yet added to PF and in iavf_close all filters was set to remove there might be a try to remove nonexistent filters on PF. Add aq_required_tmp to save aq_required flags and send them after disable_queues will be handled. Clear flags given to iavf_down different than IAVF_FLAG_AQ_GET_CONFIG as this flag is necessary to sent other aq_required. Remove some flags that we don't want to send as we are in iavf_close and we want to disable interface. Remove filters which was not yet sent and send del filters flags only when there are filters to remove.

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.
