2014-03-14i40e/i40evf: Use dma_set_mask_and_coherentMitch Williams
In Linux 3.13, dma_set_mask_and_coherent was introduced, and we have been encouraged to use it. It simplifies the DMA mapping code a bit as well.

2014-03-14i40e/i40evf: Use correct number of VF vectorsMitch Williams
Now that the 2.4 firmware reports the correct number of MSI-X vectors, use this value correctly when communicating with the VF, and when setting up the interrupt linked list. The PF has always reported the correct number of MSI-X vectors, so we should never increment the value in the vf driver.

2014-03-14i40e: Bug fix for FDIR replay logicAnjali Singhai Jain
The FDIR replay logic was being run a little too soon (before the queues were enabled) and hence the tail bump was not effective till a later transaction happened on the queue.

2014-03-14i40e: Add code to handle FD table full conditionAnjali Singhai Jain
Add code to enforce the following policy: - If the HW reports filter programming error, we check if it's due to a full table. - If so, we go ahead and turn off new rule addition for ATR and then SB in that order. - We monitor the programmed filter count, if enough room is created due to filter deletion/reset, we then re-enable SB and ATR new rule addition.

2014-03-13sh_eth: update OF PHY registerationBen Dooks
If the sh_eth device is registered using OF, then the driver should call of_mdiobus_register() to register the PHYs described in the devicetree and then use of_phy_connect() to connect the PHYs to the device. This ensures that any PHYs registered in the device tree are appropriately connected to the parent devices nodes so that the PHY drivers can access their OF properties.

More interesting changes come from Luca with some preparations for the CSA work, mostly around interface/channel combinations checking. One other possibly interesting change is a small one by myself to add NAPI support back to mac80211, which can help improve TCP behaviour through GRO." For the Bluetooth bits, Gustavo says: "This is our first pull request for 3.15, the main feature here is the addition of the privacy feature for low energy devices. Other than that we have a bunch of small improvements, fixes, and clean ups all over the tree." And... "Another pull request to 3.15. Here we have the second part of the LE private feature, the LE auto-connect feature and improvements to the power off procedures. The rest are small improvements, clean up, and fixes." For the iwlwifi bits, Emmanuel says: "I have here a whole bunch of various things. Trivial cleanups, debugfs handlers and new stuff for the new generation of devices along with new capabilities for monitor mode. We also have support for power save for dual interface mode, but that is not supported by the firmware currently available." And for the Atheros bits, Kalle says: "For ath10k Alexander did some cleanup to PCI error cases and switched ath10k to use pci_enable_msi_range(). Michal implemented AP CSA support and sta_rc_update() operation. I enabled firmware "STA quick kickout" functionality for faster detection of disappeared clients. Also there are lots of small fixes to everywhere from various people." I pulled the wireless tree to avoid some merge conflicts, and I reverted the staging patch that I had mistakenly merged previously. Along with that, mwifiex, brcmfmac, wil6210, ath9k, and a few other drivers get their usual round of updates. Also notable is the addition of yet another driver in the rtlwifi family. ... I have amended this commit request to correct the build problems in staging, including a warning added to one of the staging drivers by the wireless-next tree.

2014-03-13net: sctp: remove NULL check in sctp_assoc_update_retran_pathDaniel Borkmann
This is basically just to let Coverity et al shut up. Remove an unneeded NULL check in sctp_assoc_update_retran_path(). It is safe to remove it, because in sctp_assoc_update_retran_path() we iterate over the list of transports, our own transport which is asoc->peer.retran_path included. In the iteration, we skip the list head element and transports in state SCTP_UNCONFIRMED. Such transports came from peer addresses received in INIT/INIT-ACK address parameters. They are not yet confirmed by a heartbeat and not available for data transfers. We know however that in the list of transports, even if it contains such elements, it at least contains our asoc->peer.retran_path as well, so even if next to that element, we only encounter SCTP_UNCONFIRMED transports, we are always going to fall back to asoc->peer.retran_path through sctp_trans_elect_best(), as that is for sure not SCTP_UNCONFIRMED as per fbdf501c9374 ("sctp: Do no select unconfirmed transports for retransmissions"). Whenever we call sctp_trans_elect_best() it will give us a non-NULL element back, and therefore when we break out of the loop, we are guaranteed to have a non-NULL transport pointer, and can remove the NULL check.

2014-03-12Merge branch 'dev_kfree_skb_any'David S. Miller
Eric W. Biederman says: ==================== Using dev_kfree_skb_any for functions called in multiple contexts This patchset should be an uncontroversial set of changes to change dev_kfree_skb to dev_kfree_skb_any for code paths that are called in hard irq contexts in addition to other contexts. netpoll is the reason this code gets called in multiple contexts. There is more coming but these changes are a good starting place, and stand on their own. Since the last round changes to the rx path have been removed netpoll will changed to avoid that. ==================== Signed-off-by: David S.

2014-03-12gianfar: Carefully free skbs in functions called by netpoll.Eric W. Biederman
netpoll can call functions in hard irq context that are ordinarily called in lesser contexts. For those functions use dev_kfree_skb_any and dev_consume_skb_any so skbs are freed safely from hard irq context. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: David S.

2014-03-12benet: Call dev_kfree_skby_any instead of kfree_skb.Eric W. Biederman
Replace free_skb with dev_kfree_skb_any in be_tx_compl_process as which can be called in hard irq by netpoll, softirq context by normal napi polling, and in normal sleepable context by the network device close method.
