If dst cache dst_a copies from dst_b, and dst_b copies from dst_c, check if dst_a is expired or not, we should not end with dst_a->dst.from, dst_b, we should check dst_c. CC: Gao feng <gaofeng@cn.fujitsu.com> Signed-off-by:

dev_queue_xmit_nit() should be called right before ndo_start_xmit() calls or we might give wrong packet contents to taps users : Packet checksum can be changed, or packet can be linearized or segmented, and segments partially sent for the later case. Also a memory allocation can fail and packet never really hit the driver entry point. Reported-by:

We only ever put one skb on the send queue, and then immediately send it. Remove the queue and call dev_queue_xmit() directly. This leaves struct llc_station empty, so remove that as well. Signed-off-by:

Previously I210/I211 followed the same code flow as 82580/I350 for 1588. However, since the register sets have changed, we must update the implementation to accommodate the register changes. Cc: Richard Cochran <richardcochran@gmail.com> Signed-off-by:

In rare circumstances, it's possible a descriptor writeback will occur before a timestamped Tx packet will go out on the wire, leading to the driver believing the hardware failed to timestamp the packet. Schedule a work item for 82576 and use the available time sync interrupt registers on 82580 and above to account for this. Cc: Richard Cochran <richardcochran@gmail.com> Signed-off-by:

There are not a lot of large items, but iwlwifi, mwifiex, rt2x00, ath9k, and brcmfmac all get some attention. Wei Yongjun also provides a series of small maintenance fixes. This also includes a pull of the wireless tree in order to satisfy some prerequisites for later patches. ==================== Signed-off-by:

Noticed that the byte and packet count statistics are under- counting traffic handled by the DDP offload when there is more than one DDP completion processed in a single call to ixgbe_clean_rx_irq. This patch fixes that. I tried to optimize the setting of the rss value so that it only would have to be computed once, and only when there is a DDP completion present. Signed-off-by:

This change fixes the assumptions of the rate limiting code that previously assumed that each VF would only ever have 2 queues. This update makes it so that we now use a queues per pool value that is determined based on the VMDq feature mask. Signed-off-by:

The PF was not correctly registering any of its VLANs. As a result any VLAN tagged traffic from the VF would not be delivered to the PF because the VLAN was never assigned to the PF pool. In addition the VF was not allowed to receive traffic from VLAN 0 if it was allowed to receive untagged frames. This change corrects that so that it will correctly receive traffic from VLAN 0.

Pull GFS2 fixes from Steven Whitehouse: "Here are three GFS2 fixes for the current kernel tree. These are all related to the block reservation code which was added at the merge window. That code will be getting an update at the forthcoming merge window too. In the mean time though there are a few smaller issues which should be fixed. The first patch resolves an issue with write sizes of greater than 32 bits with the size hinting code. The second ensures that the allocation data structure is initialised when using xattrs and the third takes into account allocations which may have been made by other nodes which affect a reservation on the local node." * git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-fixes: GFS2: Take account of blockages when using reserved blocks GFS2: Fix missing allocation data for set/remove xattr GFS2: Make write size hinting code common

The lower file was being released when the eCryptfs file was closed and the dirtied pages could not be written out. - Adds a call to the lower filesystem's ->flush() from ecryptfs_flush(). - Fixes a regression, introduced in 2.6.39, when a file is renamed on top of another file. The target file's inode was not being evicted and the space taken by the file was not reclaimed until eCryptfs was unmounted. * tag 'ecryptfs-3.6-rc6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs: eCryptfs: Copy up attributes of the lower target inode after rename eCryptfs: Call lower ->flush() from ecryptfs_flush() eCryptfs: Write out all dirty pages just before releasing the lower file
