Johannes Berg dc21b54532 iwlwifi: make mac80211 ops a device config
In the future, 4965 and modern AGN devices will
need to have different mac80211 callbacks since
they have different capabilities. Prepare for
that by making the mac80211 operations a device
config.

Wey-Yi Guy 3be63ff0ae iwlwifi: move agn only eeprom functions to separate file
Some of the functions in iwl-eeprom.c file are for agn devices only,
Those functions do not have to be part of iwlcore.ko, so move those

Johannes Berg a30e3112a8 iwlwifi: move agn specific station code there
By duplicating a little bit of code between 3945
and agn, we can move a lot of code into an agn
specific station management file and thus reduce
the amount of code in core that is dead to 3945.

before:
   text	   data	    bss	    dec	    hex	filename
 212886	   3872	     96	 216854	  34f16	iwlcore.ko
 620542	  10448	    304	 631294	  9a1fe	iwlagn.ko
 314013	   3264	    196	 317473	  4d821	iwl3945.ko

after:
   text	   data	    bss	    dec	    hex	filename
 202857	   3872	     92	 206821	  327e5	iwlcore.ko
 629102	  10448	    308	 639858	  9c372	iwlagn.ko
 314240	   3264	    196	 317700	  4d904	iwl3945.ko

delta:
 -10029   iwlcore.ko
   8560   iwlagn.ko
    227   iwl3945.ko

so it's a net win even if you have both loaded,
likely because a lot of EXPORT_SYMBOLs go away.

In uCode, BT state machine need to receive open envlope
command before perform calibration; followed by close envlope
command to move to next stage.

Since Linux has two separated uCode, one for init and the second
one for runtime; we use open envlope commands for init uCode to
indicate we are ready to perform calibration operation.
But for runtime uCode, we are not doing any init calibration,
so we issue open/close envlope commands to force uCode move to
"BT COEX ON" state.

Wey-Yi Guy 6555063666 iwlwifi: add support for device tx flush request
"Flush" request can come from two different sources, it can either from
mac80211, or from device when the operation is needed. Here
adding the support for device issue "flush" request.

When receive tx complete with status is TX_STATUS_FAIL_RFKILL_FLUSH,
issue REPLY_TXFIFO_FLUSH command to uCode to flush out all the tx frames
in queues.

In this condition, since mac80211 has no knowledge of "flush" operation,
driver need to stop all the tx queues and wait for the operation
completed before wake up the queues for frames transmission.

2. drop = false: wait for either all the frames in tx fifo queues been
transmitted, or timeout; then return the control back to mac80211

If the flush request coming from mac80211, mac80211 will make sure there
are no additional frames push down to driver before flush operation is

Zhu Yi 470058e0ad iwlwifi: avoid Tx queue memory allocation in interface down
We used to free all the Tx queues memory when interface is brought
down and reallocate them again in interface up. This requires
order-4 allocation for txq->cmd[]. In situations like s2ram, this
usually leads to allocation failure in the memory subsystem. The
patch fixed this problem by allocating the Tx queues memory only at
the first time. Later iwl_down/iwl_up only initialize but don't
free and reallocate them. The memory is freed at the device removal
time. BTW, we have already done this for the Rx queue.
