Move ipw2100 and ipw2200 drivers to a new ipw/ directory. Move the obsolete ieee80211 layer which is used by these drivers to that directory as well. Add ipw_ prefix to all files of the old ieee80211 layer and to all exported symbols of the layer. Make other drivers (excluding hostap for now) use ipw_ieee80211.h.

The WRITE index points -to the _next_ packet to be written and is advanced when after the TBD has been -filled. - -The firmware pulls from the TBD queue at the READ index. The READ index points -to the currently being read entry, and is advanced once the firmware is -done with a packet. - -When data is sent to the firmware, the first TBD is used to indicate to the -firmware if a Command or Data is being sent. If it is Command, all of the -command information is contained within the physical address referred to by the -TBD. If it is Data, the first TBD indicates the type of data packet, number -of fragments, etc. The next TBD then referrs to the actual packet location. - -The Tx flow cycle is as follows: - -1) ipw2100_tx() is called by kernel with SKB to transmit -2) Packet is move from the tx_free_list and appended to the transmit pending - list (tx_pend_list) -3) work is scheduled to move pending packets into the shared circular queue. -4) when placing packet in the circular queue, the incoming SKB is DMA mapped - to a physical address. That address is entered into a TBD. Two TBDs are - filled out. The first indicating a data packet, the second referring to the - actual payload data. -5) the packet is removed from tx_pend_list and placed on the end of the - firmware pending list (fw_pend_list) -6) firmware is notified that the WRITE index has -7) Once the firmware has processed the TBD, INTA is triggered. -8) For each Tx interrupt received from the firmware, the READ index is checked - to see which TBDs are done being processed. -9) For each TBD that has been processed, the ISR pulls the oldest packet - from the fw_pend_list. -10)The packet structure contained in the fw_pend_list is then used - to unmap the DMA address and to free the SKB originally passed to the driver - from the kernel. -11)The packet structure is placed onto the tx_free_list - -The above steps are the same for commands, only the msg_free_list/msg_pend_list -are used instead of tx_free_list/tx_pend_list - -... - -Critical Sections / Locking : - -There are two locks utilized. The first is the low level lock (priv->low_lock) -that protects the following: - -- Access to the Tx/Rx queue lists via priv->low_lock. The lists are as follows: - - tx_free_list : Holds pre-allocated Tx buffers. - TAIL modified in __ipw2100_tx_process() - HEAD modified in ipw2100_tx() - - tx_pend_list : Holds used Tx buffers waiting to go into the TBD ring - TAIL modified ipw2100_tx() - HEAD modified by ipw2100_tx_send_data() - - msg_free_list : Holds pre-allocated Msg (Command) buffers - TAIL modified in __ipw2100_tx_process() - HEAD modified in ipw2100_hw_send_command() - - msg_pend_list : Holds used Msg buffers waiting to go into the TBD ring - TAIL modified in ipw2100_hw_send_command() - HEAD modified in ipw2100_tx_send_commands() - - The flow of data on the TX side is as follows: - - MSG_FREE_LIST + COMMAND => MSG_PEND_LIST => TBD => MSG_FREE_LIST - TX_FREE_LIST + DATA => TX_PEND_LIST => TBD => TX_FREE_LIST - - The methods that work on the TBD ring are protected via priv->low_lock. - -- The internal data state of the device itself -- Access to the firmware read/write indexes for the BD queues - and associated logic - -All external entry functions are locked with the priv->action_lock to ensure -that only one external action is invoked at a time. - - -*/ - -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#define __KERNEL_SYSCALLS__ -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include - -#include "ipw2100.h" - -#define IPW2100_VERSION "1.1.3" - -#define DRV_NAME "ipw2100" -#define DRV_VERSION IPW2100_VERSION -#define DRV_DESCRIPTION "Intel(R) PRO/Wireless 2100 Network Driver" -#define DRV_COPYRIGHT "Copyright(c) 2003-2005 Intel Corporation" - -/* Debugging stuff */ -#ifdef CONFIG_IPW2100_DEBUG -#define CONFIG_IPW2100_RX_DEBUG /* Reception debugging */ -#endif - -MODULE_DESCRIPTION(DRV_DESCRIPTION); -MODULE_VERSION(DRV_VERSION); -MODULE_AUTHOR(DRV_COPYRIGHT); -MODULE_LICENSE("GPL"); - -static int debug = 0; -static int mode = 0; -static int channel = 0; -static int associate = 1; -static int disable = 0; -#ifdef CONFIG_PM -static struct ipw2100_fw ipw2100_firmware; -#endif - -#include -module_param(debug, int, 0444); -module_param(mode, int, 0444); -module_param(channel, int, 0444); -module_param(associate, int, 0444); -module_param(disable, int, 0444); - -MODULE_PARM_DESC(debug, "debug level"); -MODULE_PARM_DESC(mode, "network mode (0=BSS,1=IBSS,2=Monitor)"); -MODULE_PARM_DESC(channel, "channel"); -MODULE_PARM_DESC(associate, "auto associate when scanning (default on)"); -MODULE_PARM_DESC(disable, "manually disable the radio (default 0 [radio on])"); - -static u32 ipw2100_debug_level = IPW_DL_NONE; - -#ifdef CONFIG_IPW2100_DEBUG -#define IPW_DEBUG(level, message...) \ -do { \ - if (ipw2100_debug_level & (level)) { \ - printk(KERN_DEBUG "ipw2100: %c %s ", \ - in_interrupt() ?
