mlx4_en: dont change mac_header on xmit

2012-02-26T19:22:05+00:00

A driver xmit function is not allowed to change skb without special care. mlx4_en_xmit() should not call skb_reset_mac_header() and instead should use skb->data to access ethernet header. This removes a dumb test : if (ethh && ethh->h_dest) Also remove this slow mlx4_en_mac_to_u64() call, we can use get_unaligned() to get faster code.

net/mlx4_en: adding loopback support

2011-11-27T22:17:04+00:00

Device must be in promiscuous mode or DMAC must be same as the host MAC, or else packet will be dropped by the HW rx filtering. Signed-off-by: Amir Vadai Signed-off-by: David S. Miller

net/mlx4: move RSS related definitions to be global

2011-11-27T22:17:03+00:00

Towards adding RSS support for IB drivers/application who use the mlx4 HW, make the RSS related definitions global and change the mlx4_en driver to use them. Signed-off-by: Or Gerlitz Signed-off-by: Shlomo Pongratz Signed-off-by: David S. Miller

IB/mlx4: Add support for XRC QPs

2011-10-13T16:44:18+00:00

Support the creation of XRC INI and TGT QPs. To handle the case where a CQ or PD is not provided, we allocate them internally with the xrcd. Signed-off-by: Sean Hefty Signed-off-by: Roland Dreier

IB/mlx4: Use flow counters on IBoE ports

2011-07-19T04:04:36+00:00

Allocate flow counter per Ethernet/IBoE port, and attach this counter to all the QPs created on that port. Based on patch by Eli Cohen . Signed-off-by: Or Gerlitz Signed-off-by: Roland Dreier

mlx4_core: Fix location of counter index in QP context struct

2011-07-19T04:04:33+00:00

Fix the address handle portion of the QP context structure to have the correct bit location for the counter index field. Signed-off-by: Eli Cohen Signed-off-by: Or Gerlitz Signed-off-by: Roland Dreier

mlx4: Add blue flame support for kernel consumers

2011-03-23T19:24:23+00:00

Using blue flame can improve latency by allowing the HW to more efficiently access the WQE. This patch presents two functions that are used to allocate or release HW resources for using blue flame; the caller need to supply a struct mlx4_bf object when allocating resources. Consumers that make use of this API should post doorbells to the UAR object pointed by the initialized struct mlx4_bf; Signed-off-by: Eli Cohen Signed-off-by: David S. Miller

IB/mlx4: Add VLAN support for IBoE

2010-10-25T17:20:39+00:00

This patch allows IBoE traffic to be encapsulated in 802.1Q tagged VLAN frames. The VLAN tag is encoded in the GID and derived from it by a simple computation. The netdev notifier callback is modified to catch VLAN device addition/removal and the port's GID table is updated to reflect the change, so that for each netdevice there is an entry in the GID table. When the port's GID table is exhausted, GID entries will not be added. Only children of the main interfaces can add to the GID table; if a VLAN interface is added on another VLAN interface (e.g. "vconfig add eth2.6 8"), then that interfaces will not add an entry to the GID table.

mlx4_core: Update data structures and constants for IBoE

2010-10-25T17:20:39+00:00

Add fields to hardware data structures and add new constants required for IBoE support. Signed-off-by: Eli Cohen Signed-off-by: Roland Dreier

IB/mlx4: Add support for masked atomic operations

2010-04-21T23:37:49+00:00
