2015-08-16iwlwifi: pass NAPI struct from transport layerJohannes Berg1-13/+0
The mac80211 patch to pass the NAPI struct only changed iwlwifi to store the NAPI struct, but we can do better: pass it directly from the lower transport layer to the opmode during RX, and then on to mac80211 from there. When we add multiple RX queues, we can then pass the appropriate NAPI struct properly.

2015-07-17mac80211: don't store napi structJohannes Berg1-1/+2
When introducing multiple RX queues, a single NAPI struct will not be sufficient. Instead of trying to store multiple, simply change the API to have the NAPI struct passed to the RX function. This of course means that drivers using rx_irqsafe() cannot use NAPI, but that seems a reasonable trade-off, particularly since only two of all drivers are currently using it at all. While at it, we can now remove the IEEE80211_RX_REORDER_TIMER flag again since this code path cannot have a napi struct anyway. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2015-02-01iwlwifi: allow to define the stuck queue timer per queueEmmanuel Grumbach1-1/+2
Different queue can have different behavior. While it can be unacceptable for a certain queue to be stuck for 2 seconds (e.g. the command queue), it can happen that another queue will stay stuck for even longer (a queue servicing a power saving client in GO). The op_mode can even make the timeout be a function of the listen interval. Reviewed-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-02-01iwlwifi: mvm: enable watchdog on Tx queues for mvmEmmanuel Grumbach1-5/+1
This watchdog allows to monitor the transmit queues. When a queue doesn't progress for a too long time, a timer fires and then, debug data can be collected. This watchdog has never been enabled on dvm controlled devices, so don't enable it there. In order to have it running on mvm controlled devices, we need to fix a small issue in the transport layer: mvm controlled devices use the shadow registers optimization. In this case, the watchdog wasn't running at all, even if enabled by the module parameter. Fix that on the way.

2014-12-28iwlwifi: remove MODULE_VERSIONJohannes Berg1-14/+0
The module version "in-tree:" or "in-tree:d" is useless; there should be better (functional) ways to detect whether debugging is enabled and other than that the version says nothing.

2014-04-13iwlwifi: pcie: implement GRO without NAPIJohannes Berg1-0/+12
Use the new NAPI infrastructure added to mac80211 to get GRO. We don't really implement NAPI since we don't have a real poll function and we never schedule a NAPI poll. Instead of this, we collect all the packets we got from a single interrupt and then call napi_gro_flush(). This allows us to benefit from GRO. In half duplex medium like WiFi, its main advantage is that it reduces the number of TCP Acks, hence improving the TCP Rx performance. Since we call the Rx path with a spinlock held, remove the might_sleep mention from the op_mode's API.

2014-03-09iwlwifi: return whether to stop from rfkill methodJohannes Berg1-1/+3
When indicating RF-kill toggle to the higher layer, that may in turn call back to the transport (for MVM at least) to turn off the device quickly. Instead of that, allow it to return whether or not the device should be turned off, this gets rid of the call indirection and will help make the API more consistent when we go back to non-threaded interrupts again for PCIe.

2013-12-17iwlwifi: trans: divide stop_hw into stop_device/op_mode_leaveArik Nemtsov1-2/+2
The stop_hw trans callback is not well defined. It is missing in many cleanup flows and the division of labor between stop_device/stop_hw is cumbersome. Remove stop_hw and use stop_device to perform both. Implement this for all current transports. PCIE needs some extra configuration the op-mode is leaving to configure RF kill. Expose this explicitly as a new op_mode_leave trans callback. Take the call to stop_device outside iwl_run_mvm_init_ucode, this makes more sense and WARN when we want to run the INIT firmware while it has run already.

2012-10-31iwlwifi: handle RFKILL logic in the transport layerEmmanuel Grumbach1-2/+0
No HCMD can be sent while RFKILL is asserted. If a SYNC command is running while RFKILL is asserted the fw will silently discard it. This means that the driver needs to wake the process that sleeps on the CMD_SYNC. Since the RFKILL interrupt is handled in the transport layer and the code that sleeps in CMD_SYNC is also in the transport layer, all this logic can be handled there. This simplifies the work of the op_mode. So the transport layer will now return -ERFKILL when a CMD is sent and RFKILL is asserted. This will be the case even when the CMD is SYNC. The transport layer will return -ERFKILL straight away. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2012-10-16iwlwifi: make data frame tracing optionalJohannes Berg1-0/+3
When tracing in iwlwifi, we get all data. Most of the time, we don't need it, and it just takes up a lot of extra space in the trace. Make this optional by recording the data into two separate trace events if it is needed. Without it, record only the content of non-data and EAPOL TX frames. As a result, tracing without the data tracepoints will record meta information including the 802.11 headers for all frames but will not record the contents of data frames to reduce trace overhead.
