E830 adds hardware support to prevent the VF from overflowing the PF mailbox with VIRTCHNL messages. E830 will use the hardware feature (ICE_F_MBX_LIMIT) instead of the software solution ice_is_malicious_vf(). To prevent a VF from overflowing the PF, the PF sets the number of messages per VF that can be in the PF's mailbox queue (ICE_MBX_OVERFLOW_WATERMARK). When the PF processes a message from a VF, the PF decrements the per VF message count using the E830_MBX_VF_DEC_TRIG register.

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 reStructuredText 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.
