2013-04-24net/mlx4_en: Add HW timestamping (TS) supportAmir Vadai
The patch allows to enable/disable HW timestamping for incoming and/or outgoing packets. It adds and initializes all structs and callbacks needed by kernel TS API. To enable/disable HW timestamping appropriate ioctl should be used. Currently HWTSTAMP_FILTER_ALL/NONE and HWTSAMP_TX_ON/OFF only are supported. When enabling TS on receive flow - VLAN stripping will be disabled. Also were made all relevant changes in RX/TX flows to consider TS request and plant HW timestamps into relevant structures. mlx4_ib was fixed to compile with new mlx4_cq_alloc() signature.

2013-02-07net/mlx4_en: Optimize loopback related checks in data pathYan Burman
Currently there are relatively complex conditional checks in the fast path, for TX loopback enabling and resulting RX filter logic. Move elaborate if's out of data path, replace them with a single flag for each state and update that state from appropriate places. Also, in native (non SRIOV) mode and not in loopback or in selftest, there is no need to try and filter out packets that HW loopback-ed, as in native mode we do not loopback packets anymore.

2012-07-10mlx4: Use port management change event instead of smp_snoopJack Morgenstein
The port management change event can replace smp_snoop. If the capability bit for this event is set in dev-caps, the event is used (by the driver setting the PORT_MNG_CHG_EVENT bit in the async event mask in the MAP_EQ fw command). In this case, when the driver passes incoming SMP PORT_INFO SET mads to the FW, the FW generates port management change events to signal any changes to the driver. If the FW generates these events, smp_snoop shouldn't be invoked in ib_process_mad(), or duplicate events will occur (once from the FW-generated event, and once from smp_snoop). In the case where the FW does not generate port management change events smp_snoop needs to be invoked to create these events. The flow in smp_snoop has been modified to make use of the same procedures as in the fw-generated-event event case to generate the port management events (LID change, Client-rereg, Pkey change, and/or GID change). Port management change event handling required changing the mlx4_ib_event and mlx4_dispatch_event prototypes; the "param" argument (last argument) had to be changed to unsigned long in order to accomodate passing the EQE pointer. We also needed to move the definition of struct mlx4_eqe from net/mlx4.h to file device.h -- to make it available to the IB driver, to handle port management change events.

2012-05-31net/mlx4_en: Fix improper use of "port" parameter in mlx4_en_eventJack Morgenstein
Port is used as an array index before we know if that is proper. For example, in the catas event case, port is zero; however, the port index should lie in the range (1..2). Fix this by using 'port' only in the events where it is of interest. Test for port out of range in the default (unhandled event) case, and do not output a message if it is not an ethernet port.

2012-05-17net/mlx4_en: num cores tx rings for every UPAmir Vadai
Change the TX ring scheme such that the number of rings for untagged packets and for tagged packets (per each of the vlan priorities) is the same, unlike the current situation where for tagged traffic there's one ring per priority and for untagged rings as the number of core. Queue selection is done as follows: If the mqprio qdisc is operates on the interface, such that the core networking code invoked the device setup_tc ndo callback, a mapping of skb->priority => queue set is forced - for both, tagged and untagged traffic. Else, the egress map skb->priority => User priority is used for tagged traffic, and all untagged traffic is sent through tx rings of UP 0. The patch follows the convergence of discussing that issue with John Fastabend over this thread http://comments.gmane.org/gmane.linux.network/229877 Cc: John Fastabend <john.r.fastabend@intel.com> Cc: Liran Liss <liranl@mellanox.com> Signed-off-by: Amir Vadai <amirv@mellanox.com> Signed-off-by: David S.

2012-04-05net/mlx4_en: Force user priority by QP attributeAmir Vadai
Instead of relying on HW to change schedule queue by UP, schedule queue is fixed for a tx_ring, and UP in WQE is ignored in this aspect. This resolves two issues with untagged traffic: 1. untagged traffic has no UP in packet which is needed for QoS. The change above allows setting the schedule queue (and by that the UP) of such a stream. 2. BlueFlame uses the same field used by vlan tag. So forcing UP from QPC allows using BF for untagged but prioritized traffic. In old firmware that force UP is not supported, untagged traffic will not subject to QoS. Because UP is set by QP, need to always have a tx ring per UP, even if pfcrx module paramter is false. Signed-off-by: Amir Vadai <amirv@mellanox.com> Signed-off-by: David S.
