Serial ATA Capability Register 0 (SATACR0) – Offset a8
The SATACR0.NEXT is not changed from RO to become RWO because there is an existing method (SATAGC.FLRCSSEL bit) to bypass the FLR Capability structure, and since the FLR Capability ID.NEXT is already indicating end of capability structure, it does not need change to be RWO.
