The count field in virtchnl_proto_hdrs and virtchnl_filter_action_set
should never be negative while still being valid. Changing it from
int to u32 ensures proper handling of values in virtchnl messages in
driverrs and prevents unintended behavior.
In its current signed form, a negative count does not trigger
an error in ice driver but instead results in it being treated as 0.
This can lead to unexpected outcomes when processing messages.
By using u32, any invalid values will correctly trigger -EINVAL,
making error detection more robust.

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.
