2010-08-28mlx4: use bitmap libraryAkinobu Mita
Replace loops calling set_bit() and clear_bit() with bitmap_set() and bitmap_clear(). Unlike loops calling set_bit() and clear_bit(), bitmap_set() and bitmap_clear() are not atomic. But this is ok. Because the bitmap operations are protected by bitmap->lock except for initialization of the bitmap in mlx4_bitmap_init().

2010-08-27slip: Use net_device_stats from struct net_deviceTobias Klauser
Use net_device->stats for stats instead of private variable copies in struct slip. Use ndo_get_stat64 so the additions can be performed on a private destination buffer.

2010-08-27wl12xx: remove unneeded lockingJohannes Berg
With the scan callback now being callable from any context, these unlocks/locks can go away. This makes the code easier to understand, since callers of these functions must no longer be aware that the mutex may be dropped. As Stanislaw is working on iwlwifi scanning, I didn't change it to take advantage of the new mac80211 semantics. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

2010-08-27ath5k: fix off-by-one in pilot magnitude maskBob Copeland
If the symbol offset is 46, it will be counted in both the third and fourth bytes of the mask, and in this case the shift will be negative which can pollute high order bits in the mask. This may negatively impact OFDM symbol detection. Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-08-27iwlwifi: allow using multiple contextsJohannes Berg
We're now ready to start using multiple contexts. We do this by keeping track of the valid interface types per context (exclusive [ibss] and normal) and checking which context is "free" when a new interface is added.

2010-08-27iwlwifi: follow main beacon intervalJohannes Berg
It is necessary that the PAN context always use the same beacon interval as the BSS context unless it is in dual-station mode, ie. the PAN context is a station as well, so implement that. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlagn: always send RXON timingJohannes Berg

2010-08-27iwlwifi: pass context to iwl_send_rxon_timingJohannes Berg
Sometimes we need to send RXON timing even when we don't have a virtual interface yet, so pass the context and allow passing one without a virtual interface pointer. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlwifi: send PAN parametersJohannes Berg
In order for the microcode to be able to handle multiple interfaces, we need to give it the PAN parameters that state how to allocate the time between the two interfaces. Do this, and update it wherever necessary. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlagn: send beacon before committing associated RXONJohannes Berg

2010-08-27iwlagn: send RXON timing before associatingJohannes Berg
The PAN functionality requires us to send the timing including a valid DTIM period to the microcode before associating, so request this data from mac80211 and send it to the device. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlagn: queue frames according to contextJohannes Berg
Frames for different contexts need to be put on different queues, and multicast after DTIM frames have a special queue yet which also depends on the context, so put all this into the context. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-08-27iwlagn: remove iw_mode check for beaconJohannes Berg
Since we have the beacon context now, we no longer need to rely on iw_mode but can check the beacon context interface's type. However, that check must be in the work item instead due to locking constraints (mutex must be held when dereferencing beacon_ctx pointer).

2010-08-27iwlwifi: move HT configuration data into contextJohannes Berg

2010-08-27iwlwifi: move virtual interface pointer into contextJohannes Berg

2010-08-27iwlwifi: move QoS into contextJohannes Berg

2010-08-27iwlwifi: define PAN queues/FIFOsJohannes Berg

2010-08-27iwlwifi: prepare for PAN queue/fifo assignmentJohannes Berg
PAN ucode will require a different queue assignment, in particular queue 9 instead of 4 should be used for commands. This is required because the ucode will stop/start queues 4 and 8 depending on the PAN state, since queue 8 will be used for PAN multicast (after DTIM).

2010-08-27iwlwifi: initial contextificationJohannes Berg
In order to support multiple interfaces, we must move a lot of data into per-context structures so we can use the contexts the device offers.

2010-08-25be2net: fix to dynamically generate MAC Address for VFsAjit Khaparde
The BE ASIC/firmware doesnot reserve and assign MAC address for VFs. This results in the VF interfaces being created with MAC Address 0.

These addresses are programmed in the ASIC by the PF and the VF driver queries for the MAC address during its probe. Signed-off-by: Ajit Khaparde <ajitk@serverengines.com> Signed-off-by: David S.

2010-08-25qlge: Fix a deadlock when the interface is going downBreno Leitao
Currently qlge can deadlock when the interface is going down, and the mpi_port_cfg_work() is executing on another processor. It happens because unregister_netdev() holds the rtnl lock, and the mpi_port_cfg_work() also request this lock. Since unregiter_netdev() may wait mpi_port_cfg_work(), who also request the holding lock, it can cause an deadlock, displaying the following error: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. rmmod D 00000080c6c1d190 0 3993 2081 0x00008080 Call Trace: [c000000975f56ee0] [c0000000000152a0] .__switch_to+0x100/0x1d0 [c000000975f56f70] [c0000000005781b4] .schedule+0x3a4/0x8c0 [c000000975f570c0] [c000000000578e8c] .schedule_timeout+0x24c/0x350 [c000000975f571e0] [c000000000578a88] .wait_for_common+0x198/0x210 [c000000975f572c0] [c0000000000abbb4] .__cancel_work_timer+0x2c4/0x2e0 [c000000975f57400] [d0000000078e7a20] .ql_adapter_down+0x80/0x260 [qlge] [c000000975f574b0] [d0000000078e7d80] .qlge_close+0x70/0x130 [qlge] [c000000975f57540] [c000000000497ef8] .__dev_close+0x98/0xf0 [c000000975f575d0] [c000000000497f74] .dev_close+0x24/0x60 [c000000975f57650] [c000000000498080] .rollback_registered_many+0xd0/0x2b0 [c000000975f576f0] [c000000000498338] .rollback_registered+0x38/0x50 [c000000975f57780] [c0000000004983d8] .unregister_netdevice_queue+0x88/0xe0 [c000000975f57810] [c000000000498574] .unregister_netdev+0x24/0x40 [c000000975f57890] [d0000000078f6f38] .qlge_remove+0x3c/0x78 [qlge] [c000000975f57920] [c0000000002d9298] .pci_device_remove+0x48/0x90 [c000000975f579a0] [c000000000372850] .__device_release_driver+0xa0/0x130 [c000000975f57a30] [c000000000372a08] .driver_detach+0x128/0x150 [c000000975f57ad0] [c000000000371134] .bus_remove_driver+0xc4/0x1a0 [c000000975f57b70] [c00000000037357c] .driver_unregister+0x8c/0xd0 [c000000975f57c00] [c0000000002d968c] .pci_unregister_driver+0x5c/0x110 [c000000975f57ca0] [d0000000078f6ee4] .qlge_exit+0x1c/0x34 [qlge] Signed-off-by: Breno Leitao <leitao@linux.vnet.ibm.com> Signed-off-by: Ron Mercer <ron.mercer@qlogic.com> Signed-off-by: David S.
