Wey-Yi Guy e39fdee1d7 iwlwifi: put all the isr related function under ops
There were two type of isr supported by iwlwifi devices.
  legacy isr - only used by legacy devices (3945 & 4965)
  ict isr - used by all new generation of iwlwifi devices

Move all the isr related functions into ops, the ict type of isr
supports only needed for newer devices.

Johannes Berg 2295c66b68 iwlagn: new RXON processing for modern devices
In order to simplify the flow, and make new
enhancements easier, separate out the RXON
processing for modern AGN (5000 and newer)
from RXON processing for the older 3945 and
4965 devices. Avoid changing these old ones
to avoid regressions and move their code to
a new file (iwl-legacy.c). 4965 gets the
commit_rxon that used to be common for all
AGN devices, but with removed PAN support.

The new RXON processing is more central and
does more work in committing, so that it is
easier to follow.

To make it more evident what is split out
for legacy, split the necessary operations
for that into a new struct iwl_legacy_ops.
Those parts that still exist in the new AGN
code don't need to be parametrized.

Stanislaw Gruszka 749ff4efa1 iwlwifi: avoid commit rxon during scan in iwlagn_configure_filter
Almost anywhere in the code we avoid committing rxon while performing
scan, and make rxon commit when scan complete. However in some places
in the code we do not follow that rule. This patch fix that problem in
iwlagn_configure_filter().

Since we do not commit directly in iwl3945_configure_filter, we can
also do the same for agn, so I just remove iwlcore_commit_rxon()
function and add a comment. Also change comment for iwl3945.

There are two passive 2.4 GHz channels: 12 and 13.
If you have a hidden SSID on those, you will not
be able to connect to it because we don't send out
probe requests there. We can allow this by using
the firmware's probe-after-rx functionality on
those channels as well.

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.

Johannes Berg 94597ab23e iwlagn: fix rts cts protection
Currently the driver will try to protect all frames,
which leads to a lot of odd things like sending an
RTS with a zeroed RA before multicast frames, which
is clearly bogus.

In order to fix all of this, we need to take a step
back and see what we need to achieve:
 * we need RTS/CTS protection if requested by
   the AP for the BSS, mac80211 tells us this
 * in that case, CTS-to-self should only be
   enabled when mac80211 tells us
 * additionally, as a hardware workaround, on
   some devices we have to protect aggregated
   frames with RTS

To achieve the first two items, set up the RXON
accordingly and set the protection required flag
in the transmit command when mac80211 requests
protection for the frame.

To achieve the last item, set the rate-control
RTS-requested flag for all stations that we have
aggregation sessions with, and set the protection
required flag when sending aggregated frames (on
those devices where this is required).

Since otherwise bugs can occur, do not allow the
user to override the RTS-for-aggregation setting
from sysfs any more.

Finally, also clean up the way all these flags get
set in the driver and move everything into the
device-specific functions.

John W. Linville a6e492b9b5 iwlwifi: assume vif is NULL for internal scans and non-NULL otherwise
The current practice of checking vif for NULL in one place but not
another seems to confuse some static checkers, smatch in particular.
Since vif will only be NULL in the case of internal scans, adjust the
checks accordingly.
