2017-02-19IB/hfi1: Access hfi1_ibport through rcd pointerSebastian Sanchez
Receive code paths use the QP's device and port number to access the struct hfi1_ibport. When an instance of struct hfi1_ctxtdata is present, it can be used to access struct hfi1_ibport through a pointer. This makes struct hfi1_ibport lookup time faster as an array doesn't have to be indexed and access fields in other cache-lines.

2017-02-19IB/hfi1: Use static CTLE with Preset 6 for integrated HFIsEaswar Hariharan
After extended testing, it was found that the previous PCIe Gen 3 recipe, which used adaptive CTLE with Preset 4, could cause an NMI/Surprise Link Down in about 1 in 100 to 1 in 1000 power cycles on some platforms. New EV data combined with extensive empirical data indicates that the new recipe should use static CTLE with Preset 6 for all integrated silicon SKUs.

2017-02-19IB/hfi1: Process qp wait list in IRQ thread periodicallyMike Marciniszyn
In the event that the IRQ thread is extremely busy, the processing of an rcd wait list can be delayed by quite a bit until the IRQ thread completes its work. The QP reset reference count wait can then appear to be stuck, thus causing up a QP destroy to emit the hung task diagnostic. Fix by processing the qp wait list periodically from the thread. The interval is a multiple (currently 4) of the MAX_PKT_RECV. Also, reduce some of the excessive inlining. The guidelines are per packet is ok inline, otherwise the choice is based on likelyhood of execution.

When the "ib_virt" cap is set, configuration of port capabilities need to be done through mlx5_core_modify_hca_vport_context.

2017-02-14IB/mlx4: Take source GID by index from HW GID tableTalat Batheesh
Previously, we used the HW GID index in order to search the source GID in the software GID cached table. In some cases, for example when the MAC Address of the network interface is changed, the GID cached table saves the old-IPv6-link-local GID at the end of the table. When returning the old MAC address, the software GID cached table tries to add the new IPv6-link-local GID, and when it identifies that the GID already exists, the software GID cached does not add it. Thus a mismatch occurs between the HW and the SW GID tables. It resulted with sending traffic with the wrong source GID. This commit fixes the issue by taking both from the HW table. The problem can be reproduced with the following scenario: Client: # ifconfig ens6 2.2.2.5 # ifconfig ens6 inet6 add 2001:0db8:0:f101::5/64 # ifconfig ens6 hw ether f4:52:14:61:a0:71 # ifconfig ens6 inet6 del 2001:0db8:0:f101::5/64 # ifconfig ens6 inet6 add 2001:0db8:0:f101::5/64 # ucmatose -f ipv6 -b 2001:0db8:0:f101::5 -s 2001:0db8:0:f101::6 -p 20156 Server: # ucmatose -f ipv6 -b 2001:0db8:0:f101::6 -p 20156 Fixes: 4c3eb3ca1396 ('IB/mlx4: Add VLAN support for IBoE') Signed-off-by: Talat Batheesh <talatb@mellanox.com> Reviewed-by: Maor Gottlieb <maorg@mellanox.com> Signed-off-by: Leon Romanovsky <leon@kernel.org> Signed-off-by: Doug Ledford <dledford@redhat.com>

2017-02-14IB: Query ports via the core instead of direct into the driverOr Gerlitz
Change the drivers to call ib_query_port in their get port immutable handler instead of their own query port handler. Doing this required to set the core cap flags of this device before the ib_query_port call is made, since the IB core might need these caps to serve the port query. Drivers are ensured by the IB core that the port attributes passed to the port query verb implementation are zero, and hence we removed the zeroing from the drivers.
