| * iwlwifi: mvm: Do not consider invalid HW queues in queue maskIlan Peer2015-01-221-2/+4

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is now implemented by mac80211 (commit below). mac80211 will flush/drop the frames on the queues before suspending / disconnecting.

| | * iwlwifi: mvm: abort scheduled scan upon RFKILLEmmanuel Grumbach2015-01-181-0/+7

But cancelling scheduled scan usually implies sending a command to the firwmare which has been killed as part of the RFKILL interrupt handling. Because of that, we returned an error to mac80211 when it asked to stop the scheduled scan and didn't notify the end of the scheduled scan. Besides a fat warning, this led to a situation in which cfg80211 would refuse any new scan request. To disentangle this, fake that the scheduled scan has been stopped without sending the command to the firwmare, return 0 after having properly let cfg80211 know that the scan has been cancelled. This is basically the same as: commit 9b520d84957d63348e87c0f2cbd21d86e1e8f2f2 Author: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Date: Tue Nov 4 15:54:11 2014 +0200 iwlwifi: mvm: abort scan upon RFKILL This code existed but not for all the different FW APIs we support.

When scanning on passive channels the firmware uses frag_passive_dwell to define the maximum continuous scan time before returning to the operating channel. On active channels max_out_time is the parameter used by the firmware to define the maximum time allowed out of the operating channel. Since active channels' scan should also be fragmented set max_out_time equal to frag_passive_dwell. In addition: - Set max_out_time and suspend_time if the firmware doesn't support fragmented scan to avoid unexpected behavior. - Adjust max_out_time for second level of scan precedence.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | iwl_mvm_fw_dbg_collect allows to collect debug data from the firmware. Most of the firmware interaction is done in non-sleepable context. It makes little sense to force the caller of iwl_mvm_fw_dbg_collect to sleep. Defer the actual collection to a worker so that this function will be able to be called from any context.
