* mac80211: remove module handling from rate control opsJohannes Berg2014-02-04
| | | | | | | | | | | | There's not a single rate control algorithm actually in a separate module where the module refcount would be required. Similarly, there's no specific rate control module. Therefore, all the module handling code in rate control is really just dead code, so remove it. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* mac80211: make rate control ops constJohannes Berg2014-02-04
| | | | | | | | Change the code to allow making all the rate control ops const, nothing ever needs to change them. Also change all drivers to make use of this and mark the ops const. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* wireless: delete non-required instances of include <linux/init.h>Paul Gortmaker2014-01-03
| | | | | | | | | | | | | None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

* iwlegacy: fix rate control regressionStanislaw Gruszka2013-06-12
| | | | | | | | | | Since driver does not use control.rates[0].count, we have never set that variable. But currently, after rate control API rewrite, this is required by mac80211. Otherwise legacy rates control does not work and we transmit always at 1Mbit/s on pre 11n networks. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: John W.

* | iwlegacy: 4965-rs: avoid null pointer dereference errorColin Ian King2013-03-27
|/ | | | | | | | | | | | | | | il4965_rs_initialize_lq checks to see if sta is null, however, before that check il4965_rs_use_green dereferences sta when intializing use_green.

* mac80211: stop modifying HT SMPS capabilityJohannes Berg2013-02-15
| | | | | | | | | | Instead of modifying the HT SMPS capability field for stations, track the SMPS mode explicitly in a new field in the station struct and use it in the drivers that care about it. This simplifies the code using it. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| * simple_open: automatically convert to simple_open()Stephen Boyd2012-04-05

This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open(). This replacement was done with the following semantic patch: <smpl> @ open @ identifier open_f != simple_open; identifier i, f; @@ -int open_f(struct inode *i, struct file *f) -{ ( -if (i->i_private) -f->private_data = i->i_private; | -f->private_data = i->i_private; ) -return 0; -} @ has_open depends on open @ identifier fops; identifier open.open_f; @@ struct file_operations fops = { ... -.open = open_f, +.open = simple_open, ... }; </smpl> [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* | mac80211: remove antenna_sel_tx TX info fieldJohannes Berg2012-04-10
|/ | | | | | | | | | | | | | | | | This field is never set to anything non-zero in mac80211, so we should be able to remove it. Unfortunately though, the iwlwifi and iwlegacy drivers use it for their internal TX status processing (which shouldn't be using the rate control API to start with), so add a new field "status.antenna" for them, at least for now. In the future, I plan to use the new field to hold the hardware queue, while the SKB's queue mapping holds the AC. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.
