 * 13           Copy RX Status - when set, write three receive status words
 *              to top of rx'd MPDUs.
 *              When cleared, do not write three status words (added rev 1.5)
 * 12           Reserved
 * 11           RX Complete upon FCS error - when set, give rx complete
 *              interrupt for FCS errors, after the rx filtering, e.g. unicast
 *              frames not to us with FCS error will not generate an interrupt.
 * 10           SSID Filter Enable - When set, the WiLink discards all beacon,
 *              probe request, and probe response frames with an SSID that does
 *              not match the SSID specified by the host in the START/JOIN
 *              command.
 *              When clear, the WiLink receives frames with any SSID.
 * 9            Broadcast Filter Enable - When set, the WiLink discards all
 *              broadcast frames. When clear, the WiLink receives all received
 *              broadcast frames.

 *              with a BSSID that does not match the BSSID specified by the
 *              host.
 *              When clear, the WiLink receives frames from any BSSID.
 * 4            MAC Addr Filter - When set, the WiLink discards any frames
 *              with a destination address that does not match the MAC address
 *              of the adaptor.
 *              When clear, the WiLink receives frames destined to any MAC
 *              address.
 * 3            Promiscuous - When set, the WiLink receives all valid frames
 *              (i.e., all frames that pass the FCS check).
 *              When clear, only frames that pass the other filters specified
 *              are received.
 * 2            FCS - When set, the WiLink includes the FCS with the received
 *              frame.
 *              When cleared, the FCS is discarded.
 * 1            PLCP header - When set, write all data from baseband to frame
