From Ben Hutchings. 5) Add better trace events for debugging driver datapath problems, also from Ben Hutchings. 6) Implement auto corking in TCP, from Eric Dumazet. Basically, if we have a small send and a previous packet is already in the qdisc or device queue, defer until TX completion or we get more data. 7) Allow userspace to manage ipv6 temporary addresses, from Jiri Pirko. 8) Add a qdisc bypass option for AF_PACKET sockets, from Daniel Borkmann. 9) Share IP header compression code between Bluetooth and IEEE802154 layers, from Jukka Rissanen. 10) Fix ipv6 router reachability probing, from Jiri Benc. 11) Allow packets to be captured on macvtap devices, from Vlad Yasevich. 12) Support tunneling in GRO layer, from Jerry Chu. 13) Allow bonding to be configured fully using netlink, from Scott Feldman. 14) Allow AF_PACKET users to obtain the VLAN TPID, just like they can already get the TCI. From Atzm Watanabe. 15) New "Heavy Hitter" qdisc, from Terry Lam. 16) Significantly improve the IPSEC support in pktgen, from Fan Du. 17) Allow ipv4 tunnels to cache routes, just like sockets. From Tom Herbert. 18) Add Proportional Integral Enhanced packet scheduler, from Vijay Subramanian. 19) Allow openvswitch to mmap'd netlink, from Thomas Graf. 20) Key TCP metrics blobs also by source address, not just destination address. From Christoph Paasch. 21) Support 10G in generic phylib. From Andy Fleming. 22) Try to short-circuit GRO flow compares using device provided RX hash, if provided. From Tom Herbert. The wireless and netfilter folks have been busy little bees too. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (2064 commits) net/cxgb4: Fix referencing freed adapter ipv6: reallocate addrconf router for ipv6 address when lo device up fib_frontend: fix possible NULL pointer dereference rtnetlink: remove IFLA_BOND_SLAVE definition rtnetlink: remove check for fill_slave_info in rtnl_have_link_slave_info qlcnic: update version to 5.3.55 qlcnic: Enhance logic to calculate msix vectors. qlcnic: Refactor interrupt coalescing code for all adapters. qlcnic: Update poll controller code path qlcnic: Interrupt code cleanup qlcnic: Enhance Tx timeout debugging. qlcnic: Use bool for rx_mac_learn. bonding: fix u64 division rtnetlink: add missing IFLA_BOND_AD_INFO_UNSPEC sfc: Use the correct maximum TX DMA ring size for SFC9100 Add Shradha Shah as the sfc driver maintainer. net/vxlan: Share RX skb de-marking and checksum checks with ovs tulip: cleanup by using ARRAY_SIZE() ip_tunnel: clear IPCB in ip_tunnel_xmit() in case dst_link_failure() is called net/cxgb4: Don't retrieve stats during recovery ...
| * drivers/net: delete non-required instances of include <linux/init.h>Paul Gortmaker2014-01-161-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

* mlx5: Use enum to indicate adapter page sizeEli Cohen2013-11-081-1/+1
| | | | | | | | | The Connect-IB adapter has an inherent page size which equals 4K. Define an new enum that equals the page shift and use it instead of using the value 12 throughout the code. Signed-off-by: Eli Cohen <eli@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>

| | | | | | | | | | | Change optimal_reclaimed_pages() to increase the output size of each reclaim pages command. This change reduces significantly the amount of reclaim pages commands issued to FW when the driver is unloaded which reduces the overall driver unload time.

* mlx5: Support communicating arbitrary host page size to firmwareEli Cohen2013-11-082-55/+121
| | | | | | | | | | | Connect-IB firmware requires 4K pages to be communicated with the driver. This patch breaks larger pages to 4K units to enable support for architectures utilizing larger page size, such as PowerPC. This patch also fixes several places that referred to PAGE_SHIFT instead of explicit 12 which is the inherent page shift on Connect-IB.

* mlx5: Fix cleanup flow when DMA mapping failsEli Cohen2013-11-081-5/+13
| | | | | | | | | | If DMA mapping fails, the driver cleared the object that holds the previously DMA mapped pages. Fix this by allocating a new object for the command that reports back to firmware that pages can't be supplied.

* mlx5: remove unused MLX5_DEBUG param in KconfigMichael Opdenacker2013-09-061-10/+0
| | | | | | | | | | | | This patch proposes to remove the MLX5_DEBUG kernel configuration parameter defined in drivers/net/ethernet/mellanox/mlx5/core/Kconfig, but used nowhere in the makefiles and source code. This could also be fixed by using this parameter, but this may be a leftover from driver development...

* net/mlx5_core: Support MANAGE_PAGES and QUERY_PAGES firmware command changesMoshe Lazer2013-08-154-35/+29
| | | | | | | | | | | | | | | | | | | | | | | In the previous QUERY_PAGES command version we used one command to get the required amount of boot, init and post init pages. The new version uses the op_mod field to specify whether the query is for the required amount of boot, init or post init pages. In addition the output field size for the required amount of pages increased from 16 to 32 bits. In MANAGE_PAGES command the input_num_entries and output_num_entries fields sizes changed from 16 to 32 bits and the PAS tables offset changed to 0x10. In the pages request event the num_pages field also changed to 32 bits. In the HCA-capabilities-layout the size and location of max_qp_mcg field has been changed to support 24 bits. This patch isn't compatible with firmware versions < 5; however, it turns out that the first GA firmware we will publish will not support previous versions so this should be OK.

| * mlx5_core: Implement new initialization sequenceEli Cohen2013-07-313-14/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce enbale_hca and disable_hca commands to signify when the driver starts or ceases to operate on the device. In addition the driver will use boot and init pages count; boot pages is required to allow firmware to complete boot commands and the other to complete init hca. Command interface revision is bumped to 4 to enforce using supported firmware. This patch breaks compatibility with old versions of firmware (< 4); however, the first GA firmware we will publish will support version 4 so this should not be a problem.

* mlx5: Add driver for Mellanox Connect-IB adaptersEli Cohen2013-07-0820-0/+5765
The driver is comprised of two kernel modules: mlx5_ib and mlx5_core. This partitioning resembles what we have for mlx4, except that mlx5_ib is the pci device driver and not mlx5_core. mlx5_core is essentially a library that provides general functionality that is intended to be used by other Mellanox devices that will be introduced in the future. mlx5_ib has a similar role as any hardware device under drivers/infiniband/hw.
