OID_GEN_MAXIMUM_FRAME_SIZE (Compact 2013)

  • Статья

3/26/2014

This object specifies the maximum network packet size, in bytes, that the network adapter supports. This specification does not include a header.

Remarks

In response to this query from requesting transports, the network adapter driver should indicate the maximum frame size that the transports can send, excluding the header. A network adapter driver that emulates another medium type for binding to a transport must make sure 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 network adapter driver that supports a network adapter that requires inserting fields in frames. For example, to determine the maximum transfer unit (MTU), transports send this query to a network adapter. If the network adapter driver supports 802.1p packet priority and, based on prior actions, if the network adapter driver expects that frames must traverse legacy networks before priority values are removed, that network adapter driver might indicate a smaller value in response to this query.
