Initial driver on which this is based was developed by Janusz Gorycki,

Maciej Urbaniak, and Maciej Sosnowski.

Promiscuous mode support added by Jacek Wysoczynski and Maciej Urbaniak.

Tx - Commands and Data
50
Firmware and host share a circular queue of Transmit Buffer Descriptors (TBDs)
51
Each TBD contains a pointer to the physical (dma_addr_t) address of data being
52
sent to the firmware as well as the length of the data.
54
The host writes to the TBD queue at the WRITE index. The WRITE index points
55
to the _next_ packet to be written and is advanced when after the TBD has been
58
The firmware pulls from the TBD queue at the READ index. The READ index points
59
to the currently being read entry, and is advanced once the firmware is
62
When data is sent to the firmware, the first TBD is used to indicate to the
63
firmware if a Command or Data is being sent. If it is Command, all of the
64
command information is contained within the physical address referred to by the
65
TBD. If it is Data, the first TBD indicates the type of data packet, number
66
of fragments, etc. The next TBD then refers to the actual packet location.
68
The Tx flow cycle is as follows:
70
1) ipw2100_tx() is called by kernel with SKB to transmit
71
2) Packet is move from the tx_free_list and appended to the transmit pending
73
3) work is scheduled to move pending packets into the shared circular queue.
74
4) when placing packet in the circular queue, the incoming SKB is DMA mapped
75
to a physical address. That address is entered into a TBD. Two TBDs are
76
filled out. The first indicating a data packet, the second referring to the
78
5) the packet is removed from tx_pend_list and placed on the end of the
79
firmware pending list (fw_pend_list)
80
6) firmware is notified that the WRITE index has
81
7) Once the firmware has processed the TBD, INTA is triggered.
82
8) For each Tx interrupt received from the firmware, the READ index is checked
83
to see which TBDs are done being processed.
84
9) For each TBD that has been processed, the ISR pulls the oldest packet
85
from the fw_pend_list.
86
10)The packet structure contained in the fw_pend_list is then used
87
to unmap the DMA address and to free the SKB originally passed to the driver
89
11)The packet structure is placed onto the tx_free_list
91
The above steps are the same for commands, only the msg_free_list/msg_pend_list
92
are used instead of tx_free_list/tx_pend_list
96
Critical Sections / Locking :
98
There are two locks utilized. The first is the low level lock (priv->low_lock)
99
that protects the following:
101
- Access to the Tx/Rx queue lists via priv->low_lock. The lists are as follows:
103
tx_free_list : Holds pre-allocated Tx buffers.
104
TAIL modified in __ipw2100_tx_process()
105
HEAD modified in ipw2100_tx()
107
tx_pend_list : Holds used Tx buffers waiting to go into the TBD ring
108
TAIL modified ipw2100_tx()
109
HEAD modified by ipw2100_tx_send_data()
111
msg_free_list : Holds pre-allocated Msg (Command) buffers
112
TAIL modified in __ipw2100_tx_process()
113
HEAD modified in ipw2100_hw_send_command()
115
msg_pend_list : Holds used Msg buffers waiting to go into the TBD ring
116
TAIL modified in ipw2100_hw_send_command()
117
HEAD modified in ipw2100_tx_send_commands()
119
The flow of data on the TX side is as follows:
121
MSG_FREE_LIST + COMMAND => MSG_PEND_LIST => TBD => MSG_FREE_LIST
122
TX_FREE_LIST + DATA => TX_PEND_LIST => TBD => TX_FREE_LIST
124
The methods that work on the TBD ring are protected via priv->low_lock.
126
- The internal data state of the device itself
127
- Access to the firmware read/write indexes for the BD queues
130
All external entry functions are locked with the priv->action_lock to ensure
131
that only one external action is invoked at a time.
