The size, in bytes, of the network interface's HW address.
The size, in bytes, of the network interface's media header.
The maximum size, in bytes, of the packets supported by the
network interface.
The size, in bytes, of the NVRAM device attached to the
network interface. If an NVRAM device is not attached to the
network interface, then this field will be zero. This value must
be a multiple of NvramAccessSize.
The size that must be used for all NVRAM accesses. This
means that the start address for NVRAM read and write
operations, and the total length of thoseoperation, must be a
multiple of this value. The legal values for this field are 0, 1, 2,
4, 8. If the value is zero, then no NVRAM devices are attached
to the network interface.
The multicast receive filter settings supported by the network
interface.
The current multicast receive filter settings. See "Bit Mask
Values for ReceiveFilterSetting" below.
The maximum number of multicast address receive filters
supported by the driver. If this value is zero, then the multicast
address receive filters can not be modified with ReceiveFilters().
This field may be less than

The current number of multicast address receive filters.
Array containing the addresses of the current multicast address
receive filters.
