struct buffer_addr_info buf_addr_info
Details of the physical address for a single buffer
It also contains return ownership info as well as some
meta data for SW related to this buffer.
In case of Buf_or_ext_desc_type indicating
'MSDU_buffer', this address indicates the start of the meta
data that is preceding the actual packet data.
The start of the actual packet data is provided by
field: Packet_offset

<enum 0 MSDU_buffer> The address points to an MSDU
buffer.
<enum 1 extension_descriptor> The address points to an
MSDU link extension descriptor

<legal all>
link_meta_swap
Treats link descriptor and Metadata as big-endian. The
link descriptor/Metadata is read and byte swapped.

Is set to the value 'TCL_CMD_Number' of the related
TCL_DATA command
<legal all>
data_length
Valid Data length in bytes.
MSDU length in case of direct descriptor.
Length of link extension descriptor in case of Link
extension descriptor. This is used to know the size of
Metadata.
<legal all>
ipv4_checksum_en

to_fw
Forward packet to FW along with classification result.
The packet will not be forward to TQM when this bit is set
1'b0: Use classification result to forward the packet.
1'b1: Override classification result and forward packet
only to FW.
dscp_to_tid_priority_table_id
The DSCP to tid conversion table to be used for this
frame
<legal all>
packet_offset
Packet offset from Metadata in case of direct buffer
descriptor. This field is valid when Buf_or_ext_desc_type is
reset(= 0).
<legal all>
buffer_timestamp
Field only valid when 'Buffer_timestamp_valid ' is set.
Frame system entrance timestamp. The timestamp is
related to the global system timer
Generally the first module (SW, TCL or TQM). that sees
this frame and this timestamp field is not valid, shall fill
in this field.
Timestamp in units of 1024 us
buffer_timestamp_valid
When set, the Buffer_timestamp field contains valid
info.
mesh_enable
If set to 1:
* For raw WiFi frames, this indicates transmission to a
mesh STA, enabling the interpretation of the 'Mesh Control
Present' bit (bit 8) of QoS Control (otherwise this bit is
ignored),
* For native WiFi frames, this indicates that a 'Mesh
Control' field is present between the header and the LLC.
hlos_tid_overwrite
When set, TCL shall ignore the IP DSCP and VLAN PCP
fields and use HLOS_TID as the final TID. Otherwise TCL
shall consider the DSCP and PCP fields as well as HLOS_TID
and choose a final TID based on the configured priority
<legal all>
hlos_tid
HLOS MSDU priority
Field is used when HLOS_TID_overwrite is set.
Field is also used when HLOS_TID_overwrite is not set
and DSCP/PCP is not available in the packet
<legal all>
reserved_4
<legal 0>
reserved_5
<legal 0>
reserved_6a
<legal 0>
ring_id
The buffer pointer ring ID.
0 refers to the IDLE ring
1 - N refers to other rings
Helps with debugging when dumping ring contents.
<legal all>
looping_count
A count value that indicates the number of times the
producer of entries into the Ring has looped around the
ring.
At initialization time, this value is set to 0. On the
first loop, this value is set to 1. After the max value is
reached allowed by the number of bits for this field, the
count value continues with 0 again.
In case SW is the consumer of the ring entries, it can
use this field to figure out up to where the producer of
entries has created new entries. This eliminates the need to
check where the head pointer' of the ring is located once
the SW starts processing an interrupt indicating that new
entries have been put into this ring...
Also note that SW if it wants only needs to look at the
LSB bit of this count value.
