The ice_discover_caps function is used to read the device and function capabilities, updating the hardware capabilities structures with relevant data. The exact number of capabilities returned by the hardware is unknown ahead of time. The AdminQ command will report the total number of capabilities in the return buffer. The current implementation involves requesting capabilities once, reading this returned size, and then re-requested with that size. This isn't really necessary. The firmware interface has a maximum size of ICE_AQ_MAX_BUF_LEN. Firmware can never return more than ICE_AQ_MAX_BUF_LEN / sizeof(struct ice_aqc_list_caps_elem) capabilities. Avoid the retry loop by simply allocating a buffer of size ICE_AQ_MAX_BUF_LEN. This is significantly simpler than retrying. The extra allocation isn't a big deal, as it will be released after we finish parsing the capabilities.

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.
