2013-01-30bond: have random dev address by default instead of zeroesJiri Pirko2-19/+20
Makes more sense to have randomly generated address by default than to have all zeroes. It also allows user to for example put the bond into bridge without need to have any slaves in it. Also note that this changes only behaviour of bonds with no slaves. Once the first slave device is enslaved, its address will be used (no change here). Also, fix dev_assign_type values on the way.

2013-01-29gianfar: Pack struct gfar_priv_grp into three cachelinesClaudiu Manoil2-51/+87
* remove unused members(!): imask, ievent * move space consuming interrupt name strings (int_name_* members) to external structures, unessential for the driver's hot path * keep high priority hot path data within the first 2 cache lines This reduces struct gfar_priv_grp from 6 to 3 cache lines.

2013-01-29gianfar: Optimize struct gfar_priv_tx_q for two cache linesClaudiu Manoil1-13/+12
Resize and regroup structure members to eliminate memory holes and to pack the structure into 2 cache lines (from 3). tx_ring_size was resized from 4 to 2 bytes and few members were re-grouped in order to eliminate byte holes and achieve compactness. Where possible, few members were grouped according to their usage and access order (i.e. start_xmit vs. clean_tx_ring members), less important members were pushed at the end.

Samuel says: "It brings the following goodies: - LLCP socket timestamping (To be used e.g with the recently released nfctool application for a more efficient skb timestamping when sniffing). - A pretty big pn533 rework from Waldemar, preparing the driver to support more flavours of pn533 based devices. - HCI changes from Eric in preparation for the microread driver support. - Some LLCP memory leak fixes, cleanups and slight improvements. - pn544 and nfcwilink move to the devm_kzalloc API. - An initial Secure Element (SE) API. - An nfc.h license change from the original author, allowing non GPL application code to safely include it." Also included are a pair of mac80211 pulls. Johannes says: "We found two bugs in the previous code, so I'm sending you a pull request again this soon. This contains two regulatory bug fixes, some of Thomas's hwsim beacon timer work and a documentation fix from Bob." "Another pull request for mac80211-next. This time, I have a number of things, the patches are mostly self-explanatory. There are a few fixes from Felix and myself, and random cleanups & improvements. The biggest thing is the partial patchset from Marco preparing for mesh powersave." Additionally, there are a pair of iwlwifi pulls. Johannes says: "For iwlwifi-next, I have a few cleanups/improvements as well as a few not very important fixes and more preparations for new devices." "Please pull a few updates for iwlwifi. These are just some cleanups and a debug improvement." On top of that, there is a slew of driver updates. This includes brcmfmac, mwifiex, ath9k, carl9170, and mwl8k as well as a handful of others. The bcma and ssb busses get some attention as well. Still, I don't see any big headliners here.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== This series contains updates to e1000e, ixgbevf, igb and igbvf. Majority of the patches are code cleanups of e1000e where code is removed (Yeah!). The other two e1000e patches are fixes. The first is to fix the maximum frame size for 82579 devices. The second fix is to resolve an issue with devices other than 82579 that suffer from dropped transactions on platforms with deep C-states when jumbo frames are enabled. The ixgbevf patch is to ensure that the driver fetches the correct, refreshed value for link status and speed when the values have changed. The igb and igbvf patches are a solution to an issue Stefan Assmann reported, where when the PF is up and igbvf is loaded, the MAC address is not generated using eth_hw_addr_random(). ==================== Signed-off-by: David S.

The IOMMU may stop processing page translations due to a perceived lack of credits for writing upstream peripheral page service request (PPR) or event logs. If the L2B miscellaneous clock gating feature is enabled the IOMMU does not properly register credits after the log request has completed, leading to a potential system hang. BIOSes are supposed to disable L2B micellaneous clock gating by setting L2_L2B_CK_GATE_CONTROL[CKGateL2BMiscDisable](D0F2xF4_x90[2]) = 1b.

2013-01-28net: fix possible wrong checksum generationEric Dumazet3-9/+18
Pravin Shelar mentioned that GSO could potentially generate wrong TX checksum if skb has fragments that are overwritten by the user between the checksum computation and transmit. He suggested to linearize skbs but this extra copy can be avoided for normal tcp skbs cooked by tcp_sendmsg(). This patch introduces a new SKB_GSO_SHARED_FRAG flag, set in skb_shinfo(skb)->gso_type if at least one frag can be modified by the user. Typical sources of such possible overwrites are {vm}splice(), sendfile(), and macvtap/tun/virtio_net drivers. Tested: $ netperf -H 7.7.8.84 MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 7.7.8.84 () port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 87380 16384 16384 10.00 3959.52 $ netperf -H 7.7.8.84 -t TCP_SENDFILE TCP SENDFILE TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 7.7.8.84 () port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 87380 16384 16384 10.00 3216.80 Performance of the SENDFILE is impacted by the extra allocation and copy, and because we use order-0 pages, while the TCP_STREAM uses bigger pages.

2013-01-28dm9601: support dm9620 variantPeter Korsgaard1-1/+29
dm9620 is a newer variant of dm9601 with more features (usb 2.0, checksum offload, ..), but it can also be put in a dm9601 compatible mode, allowing us to reuse the existing driver. This does mean that the extended features like checksum offload cannot be used, but that's hardly critical on a 100mbps interface. Thanks to Sławek Wernikowski <[email protected]> for providing me with a dm9620 based device to test. Signed-off-by: Peter Korsgaard <[email protected]> Signed-off-by: David S.

2013-01-28net/mlx4_en: Initialize RFS filters lock and list in init_netdevAmir Vadai1-3/+5
filters_lock might have been used while it was re-initialized. Moved filters_lock and filters_list initialization to init_netdev instead of alloc_resources which is called every time the device is configured.

2013-01-28net/mlx4_en: Fix a race when closing TX queueAmir Vadai1-1/+15
There is a possible race where the TX completion handler can clean the entire TX queue between the decision that the queue is full and actually closing it. To avoid this situation, check again if the queue is really full, if not, reopen the transmit and continue with sending the packet.

2013-01-28net/mlx4_core: Return proper error code when __mlx4_add_one failsJack Morgenstein1-2/+5
Returning 0 (success) when in fact we are aborting the load, leads to kernel panic when unloading the module. Fix that by returning the actual error code.

The device multicast list is protected by netif_addr_lock_bh in the networking core, we should use this locking practice in mlx4_en too.

2013-01-28net/mlx4_en: Fix traffic loss under promiscuous modeAviad Yehezkel1-9/+26
When port is stopped and flow steering mode is not device managed: promisc QP rule wasn't removed from MCG table. Added code to remove it in all flow steering modes. In addition, promsic rule removal should be in stop port and not in start port - moved it accordingly.

2013-01-28net/mlx4_en: Issue the dump eth statistics command under lockEugenia Emantayev1-4/+4
Performing the DUMP_ETH_STATS firmware command outside the lock leads to kernel panic when data structures such as RX/TX rings are freed in parallel, e.g when one changes the mtu or ring sizes.

2013-01-28net: phy: icplus: Use the RGMII interface mode to configure clock delaysStuart Menefy1-5/+16
Like several other PHY devices which support RGMII, the IC+1001 allows additional delays to by added to the RX_CLK and TX_CLK signals to compensate for skew between the clock and data signals. Previously this was always enabled, but this change makes use of the different RGMII interface modes to allow the user to specify whether this should be enabled.
