2014-09-03iwlwifi: mvm: use iwl_mvm_mac_get_queues_mask() moreJohannes Berg3-43/+40
There are a few places that can call the function iwl_mvm_mac_get_queues_mask() instead of open-coding the equivalent, so do that. This requires changing it to return the multicast queue as part of the bitmap, which broke GO mode because including it in the broadcast station queues seems to confuse the firmware, so work around that. Also, the API defines that the CAB queue shouldn't be included in the TFD queue mask, adjust the comment accordingly (not a bug).

2014-09-03iwlwifi: mvm: correct firmware disassoc command sequenceJohannes Berg4-23/+55
The firmware would like to have a MAC context (unassoc) before the AP station is removed (we do this) but would like to keep the BSSID until after it is removed, so we need to send two commands - one with the BSSID before and one without the BSSID after. In order to do this, we need to store the BSSID as it will have been cleared by mac80211 by the time we get notified of the disassociation. Also pass it around as an override to the various functions needing it, and keep taking it from the mac80211 data otherwise. This avoids having to keep track of the BSSID in all modes.

2014-09-03iwlwifi: consolidate hw scheduler configuration codeAvri Altman2-30/+121
Configuring the hw scheduler during queue enablement is done by writing the appropriate values to the scheduler peripherals, and it is essentially the same for all buses. Whenever writing is done via the standard iwl_write_prph, we can avoid duplicating the code for each bus. Those operations are queue deactivation, RA/TID mapping, chain-building settings, enabling/disabling aggregations and activating/deactivating the TX FIFOs. Consolidate this code using static inlines in a new header file.

2014-08-28carl9170: tx: Replace rcu_assign_pointer() with RCU_INIT_POINTER()Andreea-Cristina Bernat1-1/+1
According to RCU_INIT_POINTER()'s block comment 3.a, it can be used if "3. The referenced data structure has already been exposed to readers either at compile time or via rcu_assign_pointer() -and- a. You have not made -any- reader-visible changes to this structure since then". This case fulfills the conditions above because between the rcu_dereference() call (cvif = rcu_dereference(ar->beacon_iter);) and the rcu_assign_pointer() call there is no update of the "cvif" variable. Therefore, this patch makes the replacement. The following Coccinelle semantic patch was used: @@ identifier v; @@ v = rcu_dereference(...); ... when != rcu_dereference(...); when != v = ...; when != (<+...v...+>)++; when != \(memcpy\|memset\)(...); ( - rcu_assign_pointer + RCU_INIT_POINTER (..., v); | if(...) { ... when != v = ...; - rcu_assign_pointer + RCU_INIT_POINTER (..., v); ... when any } ) Because there are cases where between a “rcu_dereference()” call and a “rcu_assign_pointer()” call might be updates of the value that interests us, the Coccinelle semantic patch ignores them and replaces with "RCU_INIT_POINTER()" only when the update is not happening.
