Linux kernel source tree

Currently the PF tracks malicious VFs in a malvfs bitmap which is used by the ice_mbx_clear_malvf and ice_mbx_report_malvf functions. This bitmap is used to ensure that we only report a VF as malicious once rather than continuously spamming the event log. This mechanism of storage for the malicious indication works well enough for SR-IOV. However, it will not work with Scalable IOV. This is because Scalable IOV VFs can be allocated dynamically and might change VF ID when their underlying VSI changes. To support this, the mailbox overflow logic will need to be refactored. First, introduce a new ice_mbx_vf_info structure which will be used to store data about a VF. Embed this structure in the struct ice_vf, and ensure it gets initialized when a new VF is created. For now this only stores the malicious indicator bit. Pass a pointer to the VF's mbx_info structure instead of using a bitmap to keep track of these bits. A future change will extend this structure and the rest of the logic associated with the overflow detection.

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.
