A MAC address is a unique character string, and since it identifies a specific physical device — one individual NIC — the MAC address, by convention, never changes for the life of the NIC.
一个MAC地址是一个独一无二的字符串。由于它标识一个独特的物理设备——一个唯一的网卡——MAC地址，按照约定，在网卡中将永不会改变。
So, instead of catching and emulating access to physical devices below the hypervisor, new processors provide DMA address translation and permissions checking for efficient device passthrough.
因此，新的处理器提供DMA地址转换和权限检查以实现有效的设备透传，而不是捕获并模拟对管理程序下的物理设备的访问。
The never-changing MAC provides a specific, reliable address for a physical device.
而永不变化的MAC地址给物理设备提供了一个独特可靠的地址。
Then, at least one logical interface will be linked to this physical device, such as en0 or et0, on which the IP address will be configured.
至少有一个逻辑接口与这个物理设备链接，比如en0或et0，在逻辑接口上配置IP地址。
A "real" address the value that must be placed on the system address bus to select a physical memory bank or device.
物理地址：真实的地址，其值必须被置于系统地址总线中用于选择物理存储位置或者设备。
The MSI memory location is a physical bus address, so it must be translated to virtual address space both on device and host.
MSI的内存位置的物理地址，所以它必须转换为对设备和主机的虚拟地址空间。
The MSI memory location is a physical bus address, so it must be translated to virtual address space both on device and host.
MSI的内存位置的物理地址，所以它必须转换为对设备和主机的虚拟地址空间。
