2012-04-05net/mlx4_en: sk_prio <=> UP for untagged trafficAmir Vadai
Since vlan egress map is only good for tagged traffic, need to have other mapping to be used by untagged traffic. For that, the driver uses sch_mqprio mapping. This mapping could be set by using tc tool from iproute2 package. Mapped UP will be used by the HW for QoS purposes, but won't go out on the wire.

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.

2012-04-04mlx4: allocate just enough pages instead of always 4 pagesThadeu Lima de Souza Cascardo
The driver uses a 2-order allocation, which is too much on architectures like ppc64, which has a 64KiB page. This particular allocation is used for large packet fragments that may have a size of 512, 1024, 4096 or fill the whole allocation. So, a minimum size of 16384 is good enough and will be the same size that is used in architectures of 4KiB sized pages. This will avoid allocation failures that we see when the system is under stress, but still has plenty of memory, like the one below. This will also allow us to set the interface MTU to higher values like 9000, which was not possible on ppc64 without this patch.

2012-03-12mlx4_core: Scale size of MTT table with system RAMRoland Dreier
The current driver defaults to 1M MTT segments, where each segment holds 8 MTT entries. This limits the total memory registered to 8M * PAGE_SIZE which is 32GB with 4K pages. Since systems that have much more memory are pretty common now (at least among systems with InfiniBand hardware), this limit ends up getting hit in practice quite a bit. Handle this by having the driver allocate at least enough MTT entries to cover 2 * totalram pages. Signed-off-by: Roland Dreier <roland@purestorage.com>
2012-03-12mlx4_core: Allow dynamic MTU configuration for IB portsOr Gerlitz
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.

2012-03-06mlx4_core: Get rid of redundant ext_port_cap flagsOr Gerlitz
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.

From Nikola Pajkovsky. 24) The conversion of the neighbour hash tables over to RCU added a race, fixed here by adding the necessary reread of tbl->nht, fix from Michel Machado. 25) When we added VF (virtual function) attributes for network device dumps, this potentially bloats up the size of the dump of one network device such that the dump size is too large for the buffer allocated by properly written netlink applications. In particular, if you add 255 VFs to a network device, parts of GLIBC stop working. To fix this, we add an attribute that is used to turn on these extended portions of the network device dump. Sophisticaed applications like 'ip' that want to see this stuff will be changed to set the attribute, whereas things like GLIBC that don't care about VFs simply will not, and therefore won't be busted by the mere presence of VFs on a network device.

2012-02-15mlx4: fix QP tree trashingEugenia Emantayev
When adding new unicast steer entry, before moving qp to state ready, actually before calling mlx4_RST2INIT_QP_wrapper(), there were added a lot of entries with local_qpn=0 into radix tree. This fact impacted the get_res() function and proper functioning of resource tracker in addition to adding trash entries into radix tree.

2012-02-15mlx4: fix buffer overrunEugenia Emantayev
When passing MLX4_UC_STEER=1 it was translated to value 2 after mlx4_QP_ATTACH_wrapper. Therefore in new_steering_entry() unicast steer entries were added to index 2 of array of size 2.
