%description
This is a bundle package for the repacked MetaX MACA driver %{driver_version}
aarch64 payload. The build downloads the upstream Makeself installer without
executing it, then repacks the DKMS driver sources and their required firmware
and userspace payloads as separate RPM subpackages.

This package is a repackaged MetaX MACA driver aarch64 bundle. The main bundle
installs the kernel driver exclusively through DKMS. The prebuilt kernel
module, non-DKMS RDMA/GVM, and hypervisor RPM payloads are not repackaged.
The upstream Makeself installer is only extracted and is never executed.
