Pull request overview
This PR adds NVIDIA/Mellanox OFED kernel modules (mlnx-ofa_kernel 26.04) as a kernel subpackage, providing InfiniBand, Ethernet (mlx5), RDMA, and IPoIB driver support for x86_64 and aarch64. It follows the established kernel kmod framework — phase-based .inc files (package/prep/build/install/files) injected at # AZL-KMOD-*-ANCHOR sentinels via overlays — mirroring the existing nvidia-open kmod. It also ships a -devel subpackage (headers, compat shims, Module.symvers) for out-of-tree consumers.
Changes:
- New phase-based include
kmod-mlnx-ofa_kernel.incdefining the kmod + kmod-devel subpackages and their prep/build/install/files logic (extracts the inner SRPM tarball from theMLNX_OFED_SRCbundle, builds against the just-built kernel, snapshots/restoresmodules.*, strips.BTF, stages a devel tree). kernel.comp.tomloverlays register the OFED source bundle +.inc(Source6100/6101), inject the five kmod phases at the anchors, bumpazl_pkgrelease5→6, and prepend a changelog entry; new definesmlnx_ofa_version/mlnx_ofa_release/mlnx_ofa_bundle_release.- Regenerated rendered artifacts (
kernel.spec,kernel.azl.macros,sources) and refreshedlocks/kernel.lock.

Adds NVIDIA/Mellanox OFED kernel modules (mlnx-ofa_kernel 26.04) as a kernel subpackage, providing InfiniBand, Ethernet (mlx5), RDMA, and IPoIB driver support. This follows the established kmod framework pattern (similar to nvidia-open).
