OID_GEN_MAXIMUM_FRAME_SIZE (Windows CE 5.0)
This object specifies the maximum network packet size, in bytes, that the NIC supports. This specification does not include a header.
In response to this query from requesting transports, the NIC driver should indicate the maximum frame size that the transports can send, excluding the header. A NIC driver that emulates another medium type for binding to a transport must ensure that the maximum frame size for a protocol-supplied net packet does not exceed the size limitations for the true network medium. The same is true for a NIC driver that supports a NIC that requires inserting fields in frames. For example, to determine the maximum transfer unit (MTU), transports send this query to a NIC. If the NIC driver supports 802.1p packet priority and, based on prior actions, if the NIC driver expects that frames must traverse legacy networks before priority values are removed, that NIC driver might indicate a smaller value in response to this query.
Note Windows CE does not support 802.1p packet prioritization.
Requirements
OS Versions: Windows CE .NET 4.0 and later.
