* PCI: Remove DEFINE_PCI_DEVICE_TABLE macro useBenoit Taine2014-08-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to meet kernel coding style guidelines. This issue was reported by checkpatch. A simplified version of the semantic patch that makes this change is as follows (http://coccinelle.lip6.fr/): // <smpl> @@ identifier i; declarer name DEFINE_PCI_DEVICE_TABLE; initializer z; @@ - DEFINE_PCI_DEVICE_TABLE(i) + const struct pci_device_id i[] = z; // </smpl> [bhelgaas: add semantic patch] Signed-off-by: Benoit Taine <benoit.taine@lip6.fr> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

| | | | | | | | | | | | | | | | The firmware hang issue is not seen very often, though it is still seen sometimes (once in 12 hours in local tests). The changes in the driver ,to interrupt the firmware, are needed when we detect that firmware is stuck and when the host queues are full and we begin to drop packets. This is to ensure that the firmware does not miss any PPA_RDY interrupts to cause the firmware restart dont miss PPA_READY interrupt for SC2 Signed-off-by: Nishant Sarmukadam <nishants@marvell.com> Signed-off-by: Yogesh Ashok Powar <yogeshp@marvell.com> Signed-off-by: John W.

* mwl8k: remove nonstandard rate 72 MbpsJonas Gorski2013-04-221-6/+4
| | | | | | | | | | | | | | | This rate causes an overflow in the extended rates IE's data rate field, with the overflowing bit setting the Basic Rate Set membership. This results in a bogus 8 Mpbs basic rate, making clients checking them refuse association. Since the rate is likely unused anyway (HT will yield better rates between supporting chips), we can just remove it. This fixes association from wpa_supplicant and Android 4.x and newer.

* | mwl8k: always apply configuration even when device is idleJonas Gorski2013-03-271-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix settings not being applied when the device is idle and the firmware gets reloaded (because of changing from STA to AP mode). This caused the device using the wrong channel (and likely band), e.g. a 5 GHz only card still defaulted to channel 6 in the 2.4 GHz band when left unconfigured. This issue was always present, but only made visible with "mwl8k: Do not call mwl8k_cmd_set_rf_channel unconditionally" (0f4316b9), since before that the channel was (re-)configured at the next _config call even when it did not change from the mac80211 perspective.

| | | | | | | | | | | | | | | | | | | | | | Whenever TX ring is drained, priv->tx_wait still points to a valid completion. Making sure that it points to NULL before returning from the mwl8k_tx_wait_empty check.

* | mwl8k: Handle watchdog event with highest prioriryYogesh Ashok Powar2013-01-071-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, command path waits till all the tx host queues are empty. Whenever watchdog event is raised, firmware expects driver to destroy ampdu queues immediately. This requires corresponding commands i.e. mwl8k_cmd_get_watchdog_bitmap and mwl8k_destroy_ba to be sent without waiting for the tx queues to be completely empty. Use "watchdog_event_pending" to ensure the above mentioned two commands are sent down immediately.

* | mwl8k: Handle Watchdog events for the new ampdu streamsYogesh Ashok Powar2013-01-071-12/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With more ampdu streams, we need to handle watchdog events for the new ampdu streams. Handle these events appropriately. Earlier mwl8k_cmd_get_watchdog_bitmap used to return only one stream index and hence bitwise operations on the return value were not required. Now the function returns a bitmap with different bits are mapped with different stream indices.

* | mwl8k: changing mwl8k_destroy_ba prototypeYogesh Ashok Powar2013-01-071-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | Currently, mwl8k_ampdu_stream is passed as one of the argument to the function mwl8k_destroy_ba. Instead of this pass only the stream index. This will be helpful during watchdog event handling when bitmap of stream indices are received.

* | mac80211: split TX aggregation stop actionJohannes Berg2013-01-031-1/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | When TX aggregation is stopped, there are a few different cases: - connection with the peer was dropped - session stop was requested locally - session stop was requested by the peer - connection was dropped while a session is stopping The behaviour in these cases should be different, if the connection is dropped then the driver should drop all frames, otherwise the frames may continue to be transmitted, aggregated in the case of a locally requested session stop or unaggregated in the case of the peer requesting session stop. Split these different cases so that the driver can act accordingly; however, treat local and remote stop the same way and ask the driver to not send frames as aggregated packets any more. In the case of connection drop, the stop callback the driver is otherwise supposed to call is no longer required. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
