2010-04-30r8169: Fix rtl8169_rx_interrupt()Eric Dumazet
In case a reset is performed, rtl8169_rx_interrupt() is called from process context instead of softirq context. Special care must be taken to call appropriate network core services (netif_rx() instead of netif_receive_skb()). VLAN handling also corrected.

2010-04-30iwlwifi: set AMPDU status variables correctlyDaniel Halperin
The TX status code is currently abusing the ampdu_ack_map field (a bitmap) to count the number of successfully received frames. The comments in mac80211.h show there are actually three different, relevant variables, of which we are currently using two, both incorrectly. Fix this by making - ampdu_ack_len -> the number of ACKed frames (i.e. successes) - ampdu_ack_map -> the bitmap - ampdu_len -> the total number of frames sent (i.e., attempts) to match the header file (and verified with ath9k's usage) and updating Intel's RS code to match.

2010-04-30iwlwifi: set correct AC to swq_id for aggregationShanyu Zhao
When starting an aggregation session, the swq_id is generated in function iwl_virtual_agg_queue_num() where the first parameter is supposed to be the Access Class, but it used the tx fifo ID instead. This means the AC value stored in swq_id is incorrect. To test this, look at the tx_queue file in debugfs while transmitting Best Effort flow (ac=2), it shows: hwq 10: read=0 write=0 stop=0 swq_id=0xa9 (ac 1/hwq 10) After this fix, it will show: hwq 10: read=0 write=0 stop=0 swq_id=0xaa (ac 2/hwq 10) Signed-off-by: Shanyu Zhao <shanyu.zhao@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>

Some firmware versions don't behave properly when passive scanning is requested on radar channels without enabling active scanning on receiving a good frame. Work around that issue by asking the firmware to only enable the active scanning after receiving a huge number of good frames, a number that can never be reached during our dwell time.

2010-04-28iwl: cleanup: remove unneeded error handlingDan Carpenter
This is just a cleanup and doesn't change how the code works. debugfs_create_dir() and debugfs_create_file() return an error pointer (-ENODEV) if CONFIG_DEBUG_FS is not enabled, otherwise if an error occurs they return NULL. This is how they are implemented and what it says in the DebugFS documentation. DebugFS can not be compiled as a module. As a result, we only need to check for error pointers and particularly -ENODEV one time to know that DebugFS is enabled. This patch keeps the first check for error pointers and removes the rest. The other reason for this patch, is that it silences some Smatch warnings. Smatch sees the condition "(result != -ENODEV)" and assumes that it's possible for "result" to equal -ENODEV. If it were possible it would lead to an error pointer dereference. But since it's not, we can just remove the check. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: John W.

2010-04-28rt2x00: rt2800lib: update rfcsr & bbp init code for SoC devicesHelmut Schaa
Update the rfcsr and bbp init code for SoC devices to match with the latest Ralink driver. To have better control over which values are used for the register initialization create a new function rt2800_is_305x_soc which checks for SoC interface type, the correct RT chipset and the correct RF chipset. This is based on the assumption that all rt305x SoC devices use a rt2872 and rf3020/rf3021/rf3022. In case an unknown RF chipset is found on a SoC device with a rt2872 don't treat it as rt305x and just print a message.

2010-04-28wl1271: Rewrite hardware keep-alive handlingJuuso Oikarinen
The driver had a join command without keep-alive restart procedures in the channel changing code. After associated scans, the mac80211 does re-set the current channel, causing the join to occur. This would stop the hardware keep alive. To make the joins safer in this respect, this patch adds a join function that does the hardware-keep-alive magic along the join. This is now invoked in the above mentioned scenario, and also other scenarios.

2010-04-28wl1271: Improve command pollingJuuso Oikarinen
In testing I noticed that the wl1271 commands fall into two categories. In the first category are "fast" commands, these mostly take only 0 or 1 polls to complete, but occasionally upto 50 (giving a 0.5ms execution time.) In the second category, the command completion takes well more than 0.5ms (from 1.5ms upwards.) This patch fixes command polling such that it is optimal for the fast commands, but also allows sleep for the longer ones.
