2012-05-03sungem: Fix WakeOnLanGerard Lledo
WakeOnLan was broken in this driver because gp->asleep_wol is a 1-bit bitfield and it was being assigned WAKE_MAGIC, which is (1 << 5). gp->asleep_wol remains 0 and the machine never wakes up. Fixed by casting gp->wake_on_lan to bool. Tested on an iBook G4. Signed-off-by: Gerard Lledo <gerard.lledo@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Creating a VLAN interface on top of ucc_geth adds 4 bytes to the frame and the HW controller is not prepared to TX a frame bigger than 1518 bytes which is 4 bytes too small for a full VLAN frame.

2012-05-01sky2: fix receive length error in mixed non-VLAN/VLAN trafficstephen hemminger
Bug: The VLAN bit of the MAC RX Status Word is unreliable in several older supported chips. Sometimes the VLAN bit is not set for valid VLAN packets and also sometimes the VLAN bit is set for non-VLAN packets that came after a VLAN packet. This results in a receive length error when VLAN hardware tagging is enabled. Fix: Variation on original fix proposed by Mirko. The VLAN information is decoded in the status loop, and can be applied to the received SKB there. This eliminates the need for the separate tag field in the interface data structure. The tag has to be copied and cleared if packet is copied. This version checked out with vlan and normal traffic. Note: vlan_tx_tag_present should be renamed vlan_tag_present, but that is outside scope of this.

2012-04-30cxgb3: Don't call cxgb_vlan_mode until q locks are initializedRoland Dreier
The driver calls cxgb_vlan_mode() from init_one(). This calls into synchronize_rx(), which locks all the q locks, but the q locks are not initialized until cxgb_up() -> setup_sge_qsets(). So move the call to cxgb_vlan_mode() into cxgb_up(), after the call to setup_sge_qsets(). We also move the body of these functions up higher to avoid having to a forward declaration. This was found because of the lockdep warning: INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator.

2012-04-30ixgbe: fix calling skb_put on nonlinear skb assertion bugYi Zou
With the support to bounce buffer added, the skb is coming as nonlinear in the case of non-DDPed data frames for FCoE, which is mostly ok as the FCoE stack would take care of that. However, for target mode, we have to set the FC CRC and FC EOF field to allow the protocol stack to not drop the frame for the last data frame of that sequence.

Currently SDIO glue frees it's own structure before calling wl1251_free_hw(), which in turn calls ieee80211_unregister_hw(). The later call may result in a need to communicate with the chip to stop it (as it happens now if the interface is still up before rmmod), which means calls are made back to the glue, resulting in freed memory access.

2012-04-26dl2k: Clean up rio_ioctlJeff Mahoney
The dl2k driver's rio_ioctl call has a few issues: - No permissions checking - Implements SIOCGMIIREG and SIOCGMIIREG using the SIOCDEVPRIVATE numbers - Has a few ioctls that may have been used for debugging at one point but have no place in the kernel proper. This patch removes all but the MII ioctls, renumbers them to use the standard ones, and adds the proper permission check for SIOCSMIIREG. We can also get rid of the dl2k-specific struct mii_data in favor of the generic struct mii_ioctl_data. Since we have the phyid on hand, we can add the SIOCGMIIPHY ioctl too. Most of the MII code for the driver could probably be converted to use the generic MII library but I don't have a device to test the results.

2012-04-24e1000e: Fix default interrupt throttle rate not set in NIC HWJeff Kirsher
Based on the original patch from Ying Cai <ycai@google.com> This change ensures that the itr/itr_setting adjustment logic is used, even for the default/compiled-in value. Context: When we changed the default InterruptThrottleRate value from default (3 = dynamic mode) to 8000 for example, only adapter->itr_setting (which controls interrupt coalescing mode) was set to 8000, but adapter->itr (which controls the value set in NIC register) was not updated accordingly. So from ethtool, it seemed the interrupt throttling is enabled at 8000 intr/s, but the NIC actually was running in dynamic mode which has lower CPU efficiency especially when throughput is not high.

Newer devices have 20 (5000 series) or 30 (6000 series) hardware queues, rather than the 16 that 4965 had. This was added to the driver a long time ago, but improperly: the queue registers for the higher queues aren't just continuations of the registers for the first 16 queues, they are in other places. Therefore, the hardware would lock up when trying to activate queue 16 or above and the device would have to be restarted. Thanks goes to Emmanuel who identified this and told me how the queue programming should be done. Note that we don't use queues 20 and higher today and doing so needs more work than this.

2012-04-23ipw2200: Fix race condition in the command completion acknowledgeStanislav Yakovlev
Driver incorrectly validates command completion: instead of waiting for a command to be acknowledged it continues execution. Most of the time driver gets acknowledge of the command completion in a tasklet before it executes the next one. But sometimes it sends the next command before it gets acknowledge for the previous one. In such a case one of the following error messages appear in the log: Failed to send SYSTEM_CONFIG: Already sending a command. Failed to send ASSOCIATE: Already sending a command. Failed to send TX_POWER: Already sending a command. After that you need to reload the driver to get it working again. This bug occurs during roaming (reported by Sam Varshavchik) https://bugzilla.redhat.com/show_bug.cgi?id=738508 and machine booting (reported by Tom Gundersen and Mads Kiilerich) https://bugs.archlinux.org/task/28097 https://bugzilla.redhat.com/show_bug.cgi?id=802106 This patch doesn't fix the delay issue during firmware load. But at least device now works as usual after boot. Cc: stable@kernel.org Signed-off-by: Stanislav Yakovlev <stas.yakovlev@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-04-23iwlwifi: do not nulify ctx->vif on resetStanislaw Gruszka
ctx->vif is dereferenced in different part of iwlwifi code, so do not nullify it. This should address at least one of the possible reasons of WARNING at iwlagn_mac_remove_interface, and perhaps some random crashes when firmware reset is performed.

2012-04-23ath9k: fix tx power settings for AR9287Gabor Juhos
The 'ath9k_hw_update_regulatory_maxpower' helper function has been introduced by commit a55f858852e4345d0a31af593c46738ca8614bff (ath9k_hw: Cleanup TX power calculation for AR9287). Updating of the max_power_level value has been moved into the helper function in that change, however the removed code from 'ath9k_hw_ar9287_set_txpower' has not been replaced with a call of the new helper function. Due to that missing call, retrieving tx power for 2x2 and 3x3 chainmask is not handled properly. During the calculation of the tx power for 2x2 and 3x3 chainmasks the values are reduced. Those reductions must be compensated during retrieving. Fix this by adding the missing call of the helper function.

2012-04-23ath9k: add an extra boolean parameter to ath9k_hw_apply_txpowerGabor Juhos
In order to unifying regulatory limit handling commit ca2c68cc7bc80fc4504fb420df04cce99c9ee6ec (ath9k_hw: clean up tx power handling) introduced a new helper function 'ath9k_hw_apply_txpower', and the direct calls of 'ah->eep_ops->set_txpower' has been replaced by a call of the helper function. This caused a change in the behaviour of the 'ath9k_hw_set_txpowerlimit' function. The purpose of that function is to calculate and store the rate txpower table and the regulatory limit without touching the hardware registers. Before the commit, the 'test' parameter of the function was passed to the 'ah->eep_ops->set_txpower'. Now the calling of the 'set_txpower' function happens indirectly through 'ath9k_hw_apply_txpower', so the 'test' argument of the 'set_txpower' is always 'false'. This patch restores the original behaviour of 'ath9k_hw_set_txpowerlimit' by adding a new argument to 'ath9k_hw_apply_txpower.'
