2015-12-13iwlwifi: uninline iwl_trans_send_cmdEmmanuel Grumbach2-32/+35

2015-12-13iwlwifi: block the queues when we send ADD_STA for uAPSDEmmanuel Grumbach2-1/+19
We send an ADD_STA to instruct the firmware to release frames despite the peer being in PS. Since the ADD_STA command and the Tx frame that comes immediately afterwards can be reordered by the DMA engine, we need to block the Tx queues until the firmware replies with the ADD_STA response.

2015-12-13iwlwifi: trans: support a callback for ASYNC commandsEmmanuel Grumbach3-4/+21
This allows the op_mode to request from the transport to call a callback when an ASYNC commands is completed by the firmware. The same callback will be called for all the commands. Pass the command whose response triggers the callback as a parameter to the callback itself. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-12-13iwlwifi: pcie: allow the op_mode to block the tx queuesEmmanuel Grumbach4-1/+48
In certain flows (see next patches), the op_mode may need to block the Tx queues for a short period. Provide an API for that. The transport is in charge of counting the number of times the queues are blocked since the op_mode may block the queues several times in a row before unblocking them.

iwl_mvm_restart_cleanup() calls ieee80211_remain_on_channel_expired() on cleanup, but it doesn't clean the actual roc time events, resulting in failure of further ROC attempts.

2015-12-13iwlwifi: mvm: set default new STA as non-aggregatedLiad Kaufman1-0/+2
When sending the first ADD_STA HCMD for a STA, the %add_modify field indicates an addition of a STA and not a modification of one. In such a case, all fields of the HCMD are used to initialize the corresponding fields in the FW, regardless of what bits are set in %modify_mask. Set the %tid_disable_tx field to mvm_sta->tid_disable_agg in iwl_mvm_sta_send_to_fw(). If the STA is only updated this will have no effect, but if it is added - it will make sure the STA starts with the correct queues - if any - configured as non-aggregated by default (until told otherwise).

2015-12-11iwlegacy: mark il_adjust_beacon_interval as noinlineArnd Bergmann1-1/+1
With the new optimized do_div() code, some versions of gcc produce obviously incorrect code that leads to a link error in iwlegacy/common.o: drivers/built-in.o: In function `il_send_rxon_timing': :(.text+0xa6b4d4): undefined reference to `____ilog2_NaN' :(.text+0xa6b4f0): undefined reference to `__aeabi_uldivmod' In a few thousand randconfig builds, I have seen this problem a couple of times in this file, but never anywhere else in the kernel, so we can try to work around this in the only file that shows the behavior, by marking the il_adjust_beacon_interval function as noinline, which convinces gcc to use the unoptimized do_div() all the time.

2015-12-07iwlwifi: mvm: don't keep an mvm ref when the interface is downLuca Coelho2-13/+13
There is no reason to keep a reference when the interface is down, since we are not really doing anything. The reference is only needed when the mac80211 start op (or a hw restart) is running, to prevent going into runtime or system supend in the meantime. This will allow us to support runtime PM when the interface is down (in another patch).

2015-12-01iwlwifi: mvm: ROC: Extend the ROC max delay duration & limit ROC durationMatti Gottlieb1-4/+38
When associated to an AP and a ROC event with a long duration is scheduled the FW may have a hard time scheduling a consecutive time event, since it has to remain on the connection channel to hear the AP's DTIM. In addition, when associated and a ROC is requested with a duration greater than the DTIM interval, the FW will not be able to schedule the ROC event, since it needs to wake up for the DTIM. Increasing the "max delay" duration to the DTIM period will allow the FW to wait until after the DTIM and then schedule the ROC time event. Limiting the ROC to be less than the DTIM interval will assure that the time event will be scheduled for at least part of the time (instead of automatically failing) Extend the ROC max delay duration to min(dtim_interval * 3, 600TU), and limit the duration to be less than the DTIM interval.

2015-12-01iwlwifi: mvm: use firmware station lookup, combine codeJohannes Berg2-17/+29
In most cases, the firmware will already match the station that we received a given frame from and tell us the station ID in the RX status, so we can look up the station from that. This lets us skip the (more expensive) hash table lookup in mac80211. Also change the fallback case (no station info from the firmware) to not attempt to look up a multicast source address.
