mlx4_core: Allow dynamic MTU configuration for IB ports

2012-03-12T23:24:59Z

Set the MTU for IB ports in the driver instead of using the firmware default of 2KB (the driver defaults to 4KB). Allow for dynamic mtu configuration through a new, per-port sysfs entry. Since there's a dependency between the port MTU and the max number of HW VLs the port can support, apply a mim/max approach, using a loop that goes down from the highest possible number of VLs to the lowest, using the firmware return status to know whether the requested number of VLs is possible with a given MTU. For now, as with the dynamic link type change / VPI support, the sysfs entry to change the mtu is exposed only when NOT running in SR-IOV mode. To allow changing the MTU for the master in SR-IOV mode, primary-function-initiated FLR (Function Level Reset) needs to be implemented. Signed-off-by: Or Gerlitz Signed-off-by: Roland Dreier

mlx4_core: Get rid of redundant ext_port_cap flags

2012-03-07T01:25:18Z

While doing the work for commit a6f7feae6d ("IB/mlx4: pass SMP vendor-specific attribute MADs to firmware") we realized that the firmware would respond on all sorts of vendor-specific MADs. Therefore commit 97285b7817 ("mlx4_core: Add extended port capabilities support") adds redundant code into the driver, since there's no real reaon to maintain the extended capabilities of the port, as they can be queried on demand (e.g the FDR10 capability). This patch reverts commit 97285b7817 and removes the check for extended caps from the mlx4_ib driver port query flow. Signed-off-by: Or Gerlitz Signed-off-by: Roland Dreier

net/mlx4: fixing sparse warnings for not declared, functions

2012-03-06T20:19:18Z

The SET_PORT functions are implemented in port.c, which is part of mlx4_core, these functions are exported. The functions are in use by the mlx4_en module (were originally part of mlx4_en). Their declaration remained in mlx4_en module, moving the declaration to the right location. Signed-off-by: Yevgeny Petrilin Signed-off-by: David S. Miller

mlx4: Enforce device max FMR maps in FMR alloc

2012-02-26T09:43:37Z

ConnectX devices have a limit on the number of mappings that can be done on an FMR before having to call sync_tpt. The current mlx4_ib driver reports the limit correctly in max_map_per_fmr in .query_device(), but mlx4_core doesn't check it when actually allocating FMRs. Add a max_fmr_maps field to struct mlx4_caps and enforce this maximum value on FMR allocations. Signed-off-by: Eli Cohen Signed-off-by: Roland Dreier

mlx4_en: eth statistics modification

In native mode display all available staticstics. In SRIOV mode on VF display only SW counters statistics, in SRIOV mode on hypervisor display SW counters and errors (got from FW) statistics. Signed-off-by: Eugenia Emantayev Reviewed-by: Yevgeny Petrilin Signed-off-by: David S. Miller

mlx4_core: Changing link sensing logic

2011-12-19T19:57:07Z

New FW can give clues to driver regarding default port type and whether or not we should default to link sensing on the port. 2 bits are added to QUERY_PORT command: 1. suggested_type: This bit gives a hint whether the default port type should be IB or Ethernet. The driver will use this hint in case the user didn't specify explicitly the link layer type he wants to set. 2. default_sense: If this bit is set, we would sense the port type on start-up and default the port to link sensing Signed-off-by: Yevgeny Petrilin Signed-off-by: David S.

mlx4: capability for link sensing

2011-12-19T19:57:06Z

For ConnectX3 devices, we allow link sensing only if FW explicitly reported it supports the feature. For older versions (ConnectX1 and 2), if the card supports both link layer types (Ethenet and Infiniband), link sensing is supported. Signed-off-by: Yevgeny Petrilin Signed-off-by: David S. Miller
