Pull networking changes from David Miller: "Noteworthy changes this time around: 1) Multicast rejoin support for team driver, from Jiri Pirko. 2) Centralize and simplify TCP RTT measurement handling in order to reduce the impact of bad RTO seeding from SYN/ACKs. Also, when both timestamps and local RTT measurements are available prefer the later because there are broken middleware devices which scramble the timestamp. From Yuchung Cheng. 3) Add TCP_NOTSENT_LOWAT socket option to limit the amount of kernel memory consumed to queue up unsend user data. From Eric Dumazet. 4) Add a "physical port ID" abstraction for network devices, from Jiri Pirko. 5) Add a "suppress" operation to influence fib_rules lookups, from Stefan Tomanek. 6) Add a networking development FAQ, from Paul Gortmaker. 7) Extend the information provided by tcp_probe and add ipv6 support, from Daniel Borkmann. 8) Use RCU locking more extensively in openvswitch data paths, from Pravin B Shelar. 9) Add SCTP support to openvswitch, from Joe Stringer. 10) Add EF10 chip support to SFC driver, from Ben Hutchings. 11) Add new SYNPROXY netfilter target, from Patrick McHardy. 12) Compute a rate approximation for sending in TCP sockets, and use this to more intelligently coalesce TSO frames. Furthermore, add a new packet scheduler which takes advantage of this estimate when available. From Eric Dumazet. 13) Allow AF_PACKET fanouts with random selection, from Daniel Borkmann. 14) Add ipv6 support to vxlan driver, from Cong Wang" Resolved conflicts as per discussion. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1218 commits) openvswitch: Fix alignment of struct sw_flow_key. netfilter: Fix build errors with xt_socket.c tcp: Add missing braces to do_tcp_setsockopt caif: Add missing braces to multiline if in cfctrl_linkup_request bnx2x: Add missing braces in bnx2x:bnx2x_link_initialize vxlan: Fix kernel panic on device delete. net: mvneta: implement ->ndo_do_ioctl() to support PHY ioctls net: mvneta: properly disable HW PHY polling and ensure adjust_link() works icplus: Use netif_running to determine device state ethernet/arc/arc_emac: Fix huge delays in large file copies tuntap: orphan frags before trying to set tx timestamp tuntap: purge socket error queue on detach qlcnic: use standard NAPI weights ipv6:introduce function to find route for redirect bnx2x: VF RSS support - VF side bnx2x: VF RSS support - PF side vxlan: Notify drivers for listening UDP port changes net: usbnet: update addr_assign_type if appropriate driver/net: enic: update enic maintainers and driver driver/net: enic: Exposing symbols for Cisco's low latency driver ...

IB/mlx4: Add receive flow steering support

2013-08-28T16:53:56Z

Implement ib_create_flow() and ib_destroy_flow(). Translate the verbs structures provided by the user to HW structures and call the MLX4_QP_FLOW_STEERING_ATTACH/DETACH firmware commands. On the ATTACH command completion, the firmware provides a 64-bit registration ID, which is placed into struct mlx4_ib_flow that wraps the instance of struct ib_flow which is retuned to caller. Later, this reg ID is used for detaching that flow from the firmware. Signed-off-by: Hadar Hen Zion Signed-off-by: Or Gerlitz Signed-off-by: Roland Dreier

include: Convert ethernet mac address declarations to use ETH_ALEN

2013-08-02T19:33:54Z

It's convenient to have ethernet mac addresses use ETH_ALEN to be able to grep for them a bit easier and also to ensure that the addresses are __aligned(2). Add #include as necessary. Signed-off-by: Joe Perches Acked-by: Mauro Carvalho Chehab Signed-off-by: David S. Miller

net/mlx4_core: Respond to operation request by firmware

2013-07-29T08:12:40Z

This commit adds new firmware command and new firmware event. The firmware raises the MLX4_EVENT_TYPE_OP_REQUIRED event in order to signal the driver it needs to perform an administrative operation throughout the MLX4_CMD_GET_OP_REQ command. At the moment the supported operation is adding/removing multicast entries which are used by the firmware for handling NCSI traffic in B0 steering mode. Also, had to swap the order of mlx4_init_mcg_table() and mlx4_init_eq_table() to make sure that driver will get events only after resources are initialized to handle it.

net/mlx4_core: Add HW enforcement to VF link state

2013-07-01T20:10:57Z

When the firmware supports the UPDATE_QP command, if the VF link is disabled, block all QPs opened by the VF, by programming the UPDATE_QP command to drop all RX & TX traffic to/from these QPs. Operates only in VST mode. Signed-off-by: Rony Efraim Signed-off-by: Or Gerlitz Signed-off-by: David S. Miller

net/mlx4_core: Dynamic VST to VST vlan/qos changes

2013-07-01T20:10:22Z

Within VST mode, enable modifying the vlan and/or qos for a VF without requiring unbind/rebind. This requires firmware which supports the UPDATE_QP command. (If the command is not available, we fall back to requiring unbind/bind to activate these changes). To avoid race conditions with modify-qp on QPs that are affected by update-qp, this operation is performed on the comm_wq. If the update operation succeeds for all the necessary QPs, a vlan_unregister is performed for the abandoned vlan id. Signed-off-by: Jack Morgenstein Signed-off-by: Or Gerlitz Signed-off-by: David S.

net/mlx4: Strengthen VLAN tags/priorities enforcement in VST mode

2013-05-11T23:12:44Z

Make sure that the following steps are taken: - drop packets sent by the VF with vlan tag - block packets with vlan tag which are steered to the VF - drop/block tagged packets when the policy is priority-tagged - make sure VLAN stripping for received packets is set - make sure force UP bit for the VF QP is set Use enum values for all the above instead of numerical bit offsets.
