A note regarding fwctl support: Generally as of mstflint 4.31, some of the functionality, and specifically firmware loading, can work through the new fwctl interface and does not require the separate mstflint_access from mstflint-dkms. However, The version included in mstflint 4.31 is one that matches older out-of-tree patches versions of fwctl while that code was in development. Once mstflint 4.32 is released, it will use the version of the interface merged into kernel 6.15 and that should be considered stable. So the short version: The fwctl code in this package here will not work.
