* carl9170: fix allmulticast modeNicolas Cavallari2011-05-051-1/+1
| | | | | | | | | | | | | | | | | | Currently, the driver only disable multicast filtering when the FIF_ALLMULTI driver flag has been just set (ie, if changed_flags& FIF_ALLMULTI and *new_flags& FIF_ALLMULTI) or else it will reenable multicast filtering. But next time, this condition will be false and multicast filtering will be reenabled, even through FIF_ALLMULTI is still set. This mean that allmulticast only works for less than two minutes in ad-hoc mode. This patch fixes that to disable multicast filtering as long as FIF_ALLMULTI is set.

* mwifiex: fix simultaneous assoc and scan issueAmitkumar Karwar2011-05-052-6/+9
| | | | | | | | | | | | | | | | | | | | | When scan and assoc (infra/ibss) commands are simultaneously given in two terminals, association response is erroneously served while serving the scan response. mwifiex_cfg80211_results() is the common routine for sending ioctl (scan, assoc etc.) results to cfg80211 stack. In above scenario even if the common routine is called for scan ioctl context, it also tries to send information about assoc ioctl to cfg80211 because "priv->assoc_request/priv->ibss_join_request" flag is on at that time. Fix the issue by updating request variable after assoc handling and modifying the variable check in mwifiex_cfg80211_results.

* libertas: remove tx_timeout handlerDaniel Drake2011-05-051-23/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As described at http://marc.info/?l=linux-netdev&m=130428493104730&w=2 libertas frequently generates spurious tx timeouts, because the tx queue is brought down for extended periods during scanning. The net layer takes a look and incorrectly assumes the queue has been down for several seconds, and generates a tx_timeout. One way to fix this is to bump the trans_start counter while scanning so that the network layer knows that the device is still alive, but I think the tx_timeout handler is implemented wrongly here and not of any real use, so I vote to remove it. As explained at http://marc.info/?l=linux-wireless&m=130430311115755&w=2 the watchdog is primarily meant to deal with lockup on the hardware TX path (detected by the tx queue being stopped for an extended period of time), but this is unlikely to happen with libertas. In this case, the tx queue is stopped only while waiting for lbs_thread to send the queued frame to the driver, and lbs_thread wakes up the queue immediately after, even if the frame could not be sent correctly. So, the only hardware-related possibility that this catches is if hw_host_to_card hangs - this is something I have never seen. And if it were to happen, nothing done by lbs_tx_timeout would actually wake up lbs_thread any quicker than otherwise. Removing this oddly-behaving spuriously-firing tx_timeout handler should fix an occasional kernel crash during resume (http://dev.laptop.org/ticket/10748) Signed-off-by: Daniel Drake <dsd@laptop.org> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | When operating as AP, the TX queues are not stopped when we start recovery. mac80211 is notified only after the fact. When there is pending TX, it will be queued even after the FW is down. This leads to situations where the TX queues are stopped (because of the TX-watermark mechanism), and are never woken up when we return from recovery.

| | | | | | | | | | | | | | | | | | | | | | | | | | The FW can dynamically manage its internal TX & RX memory pools, moving blocks from one pool to another when necessary. This can significantly improve performance. Currently this feature is enabled only for 128x. Enable dynamic memory for 127x as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver stops sending TX packets when either there aren't enough memory blocks, or it runs out of TX descriptors. The driver continues to send packets to the FW only when more memory blocks are available. The FW might free TX descriptors without freeing the corresponding memory blocks, especially when dynamic memory is enabled. In cases where memory blocks are not freed at all, the driver will keep waiting for more memory blocks indefinitely.

Temporarily, the memory configuration for the 127x was used both for 127x/AP as well as 128x/AP. Since the two chips don't have the same number of memory blocks, TP was significantly degraded. This hasn't been fine tuned yet, but using the base 128x numbers (without dynamic memory) seems to yield much better results (around 30% more). Additional fine tuning will be required in the future.

Since the driver relies solely on the BSS_CHANGED_ASSOC flag, without checking if there was an actual change, it will end up issuing unjoin() and dummy_join() commands, although it was never associated and should just remain idle. Avoid it by checking the actual state change, in addition to the "changed" flag.
