On architectures such as ARM64 a regular memset() may\nemit unaligned or block-zeroing instructions (e.g. DC ZVA) that are\ninvalid on Device memory, leading to a synchronous external abort.\n\nUse memset_io() to clear the slot for QLAFX00, matching the I/O\naccessors used elsewhere on this ring. Other adapters keep the plain\nmemset() on their DMA-coherent rings. The zero-fill is retained for FX00\nbecause its IOCB builders (e.g. qlafx00_fxdisc_iocb()) copy only part of\nthe entry and rely on the unused tail being pre-zeroed."
