2009-04-28e100: do not go D3 in shutdown unless system is powering offThadeu Lima de Souza Cascardo
After experimenting with kexec with the last merges after 2.6.29, I've had some problems when probing e100. It would not read the eeprom. After some bisects, I realized this has been like that since forever (at least 2.6.18). The problem is that shutdown is doing the same thing that suspend does and puts the device in D3 state. I couldn't find a way to get the device back to a sane state in the probe function. So, based on some similar patches from Rafael J. Wysocki for e1000, e1000e, and ixgbe, I wrote this one for e100.

2009-04-27ixgbe: Fix WoL functionality for 82599 KX4 devicesWaskiewicz Jr, Peter P
The current code writes the PME enabled bit in PCI config space which is wrong. This was needed for pre-release hardware, and was not removed from the driver. Also, we need to clear the WUS (wake up status) after we resume. Otherwise we can't wake for the same event again since it's still asserted in the hardware. Plus, the multicast lists were being written improperly, causing multicast WoL to fail.

2009-04-228139too: fix HW initial flowJianjun kong
While ifconfig eth0 up kernel calls open() of 8139 driver(8139too.c). In rtl8139_hw_start() of rtl8139_open(), 8139 driver enable RX before setting up the DMA buffer address. In this interval where RX was enabled and DMA buffer address is not yet set up, any incoming broadcast packet would be send to a strange physical address: 0x003e8800 which is the default value of DMA buffer address. Unfortunately, this address is used by Linux kernel. So kernel panics. This patch fix it by setting up DMA buffer address before RX enabled and everything is fine even under broadcast packets attack.

2009-04-21iwlwifi: DMA fixesReinette Chatre
A few issues wrt DMA were uncovered when using the driver with swiotlb. - driver should not use memory after it has been mapped - iwl3945's RX queue management cannot use all of iwlagn because the size of the RX buffer is different. Revert back to using iwl3945 specific routines that map/unmap memory. - no need to "dma_syn_single_range_for_cpu" followed by pci_unmap_single, we can just call pci_unmap_single initially - only map the memory area that will be used by device. this is especially relevant to the mapping of iwl_cmd. we should not map the entire structure because the meta data at the beginning of structure contains the address to be used later for unmapping. If the address to be used for unmapping is stored in mapped data it creates a problem. - ensure that _if_ memory needs to be modified after it is mapped that we call _sync_single_for_cpu first, and then release it back to device with _sync_single_for_device - we mapped the wrong length of data for host commands, with mapped length differing with length provided to device, fix that.

2009-04-21iwlwifi: add debugging for TX pathReinette Chatre
When debugging TX issues it is helpful to know the seq nr of the frame being transmitted. The seq nr is printed as part of ucode's log informing us which frame is being processed. Having this information printed in driver log makes it easy to match activities between driver and firmware. Also make possible to print TX flags directly. These are already printed as part of entire TX command, but having it printed directly in cpu format makes it easier to look at.

2009-04-20tun: Fix sk_sleep races when attaching/detachingHerbert Xu
As the sk_sleep wait queue actually lives in tfile, which may be detached from the tun device, bad things will happen when we use sk_sleep after detaching. Since the tun device is the persistent data structure here (when requested by the user), it makes much more sense to have the wait queue live there. There is no reason to have it in tfile at all since the only time we can wait is if we have a tun attached. In fact we already have a wait queue in tun_struct, so we might as well use it.

2009-04-20tun: Only free a netdev when all tun descriptors are closedHerbert Xu
The commit c70f182940f988448f3c12a209d18b1edc276e33 ("tun: Fix races between tun_net_close and free_netdev") fixed a race where an asynchronous deletion of a tun device can hose a poll(2) on a tun fd attached to that device. However, this came at the cost of moving the tun wait queue into the tun file data structure. The problem with this is that it imposes restrictions on when and where the tun device can access the wait queue since the tun file may change at any time due to detaching and reattaching. In particular, now that we need to use the wait queue on the receive path it becomes difficult to properly synchronise this with the detachment of the tun device. This patch solves the original race in a different way. Since the race is only because the underlying memory gets freed, we can prevent it simply by ensuring that we don't do that until all tun descriptors ever attached to the device (even if they have since be detached because they may still be sitting in poll) have been closed. This is done by using reference counting the attached tun file descriptors. The refcount in tun->sk has been reappropriated for this purpose since it was already being used for that, albeit from the opposite angle. Note that we no longer zero tfile->tun since tun_get will return NULL anyway after the refcount on tfile hits zero. Instead it represents whether this device has ever been attached to a device.

Stop napi processing before flushing the work queue. The ULP drivers (iSCSI, iWARP) might also schedule a task on keventd_wk while releasing a connection handle (cxgb3_offload.c::cxgb3_queue_tid_release()).

2009-04-17macb: process the RX ring regardless of interrupt statusErik Waling
Suppose that we receive lots of frames, start processing them, but exhaust our budget so that we return before we had a chance to look at all of them. Then, when the network layer calls us again, we will only continue processing the buffers if the REC bit was set in the mean time, which it might not be if there was a brief pause in the flow of packets. If this happens, we'll simply display a warning and call netif_rx_complete() with potentially lots of unprocessed packets in the RX ring...
