in qmimux_rx_fixup\n\nRaw IP packets have no MAC header, leaving skb->mac_header uninitialized.\nThis can trigger kernel panics on ARM64 when xfrm or other subsystems\naccess the offset due to strict alignment checks.\n\nInitialize the MAC header to prevent such crashes.\n\nThis can trigger kernel panics on ARM when running IPsec over the\nqmimux0 interface.\n\nExample trace:\n\n    Internal
