OID_IRDA_SUPPORTED_SPEEDS
The OID_IRDA_SUPPORTED_SPEEDS OID requests that the miniport driver return the link speeds that it supports. In response, the miniport driver returns an array of DWORDS, each of which indicates a supported speed at which the miniport driver can transmit outgoing frames and receive incoming frames. IrLAP sets OID_IRDA_LINK_SPEEDto one of the supported values before passing send packets to the miniport driver.
