7 ClearAID Used only by an AP!!!
Used to clear the failed transmit state of an
association ID.
Once a packet fails to a particular AID, all packets to
that AID will be returned to the AP (without any
attempts), until the ClearAID bit is set.
This mechanism allows flushing of queued packets
to maintain the correct packet order.
8 Strict Order Indicates a strictly ordered multicast packet.
The packet will not be queued for transmission after
the DTIM, but rather will be sent with normal
priority.
See 802.11 specification for details on strictly
ordered.
9 Use RTS Forces the use of RTS/CTS for transmission of this
packet. This is useful for resubmission of previously
failed packets to start transmission with RTS/CTS
enabled.
+0x000A AID u16 Association ID. Used only by an AP!!!.
+0x000C TxRetry u16 Output Retry Status for the FID from the PC4500/4800.
This contains the number of retries required to transmit the
packet.
The upper byte is the short retry count.
The lower byte is the long retry count.
(Number of retries reported will be limited to 255 for both
short/long).
This field will return a zero if no retries were required.
+0x000E TxAssociationCou
nt
u8 Used only by an AP Repeater!!!.
Transmissions will be returned to the host with a status
Of Cancelled due to loss of association, if this field does
not match the current association count.
This is done to allow for retargeting of packets when
reassociation to a new parent access point occurs.
+0x000F Transmit Bit Rate u8 Must be used by an AP!!!. Selects the desired transmission
rate. (Value in multiples of 500 Kbps. 0x02=1Mbps,
0x04=2Mbps). A value of 0 for a client means the client
will choose the best rate for delivery.
+0x0010 MaxLongRetries u8 Used only on AP. Maximum long retry count.
+0x0011 MaxShortRetries u8 Used only on AP. Maximum short retry count.
+0x0012 Reserved u8[2]
802.11 Header
For transmit, the following section must be filled in if the
TxControl.Type is 802.11.
+0x0014 FrameControl u16 Frame Control Word as defined in 802.11.
+0x0016 Duration u16 The duration field as defined in 802.11.
This field will always be overridden by the PC4500/4800
+0x0018 Addr1 u8[6] The address1 field as defined in 802.11.
+0x001E Addr2 u8[6] The address2 field as defined in 802.11.
+0x0024 Addr3 u8[6] The address3 field as defined in 802.11.
+0x002A Sequence u16 The sequence control field as defined in 802.11.
This field will always be overridden by the PC4500/4800.
+0x002C Addr4 u8[6] The address4 field as defined in 802.11.
Note, this field will only be used if both the FromDS and
ToDS bits are set in the FrameControl.
+0x0032 GapLen u16 The length of the Gap field in bytes.
On receive, the GapLen will be 0, 2 or 8.
For transmit FIDs with a 802.3 header, the gap len is 0.
For transmit FIDs without 802.3 header, the gap len is 6.
