Enable returning FDIR completion status by checking the ctrl_vsi Rx queue descriptor value. To enable returning FDIR completion status from ctrl_vsi Rx queue, COMP_Queue and COMP_Report of FDIR filter programming descriptor needs to be properly configured. After program request sent to ctrl_vsi Tx queue, ctrl_vsi Rx queue interrupt will be triggered and completion status will be returned. Driver will first issue request in ice_vc_fdir_add_fltr(), then pass FDIR context to the background task in interrupt service routine ice_vc_fdir_irq_handler() and finally deal with them in ice_flush_fdir_ctx(). ice_flush_fdir_ctx() will check the descriptor's value, fdir context, and then send back virtual channel message to VF by calling ice_vc_add_fdir_fltr_post(). An additional timer will be setup in case of hardware interrupt timeout.

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.
