ib_pack.h: Fix commentary IBA reference for CNP in IB opcode enum

2015-10-21T20:41:54+00:00

IBA spec is now 1.3 not 3.1 and vol 1 should be mentioned as there is also vol 2. Signed-off-by: Hal Rosenstock Signed-off-by: Doug Ledford

IB/core: Add core header changes needed for OPA

2015-08-29T02:54:50+00:00

This patch adds the value of the CNP opcode to the existing list of enumerated opcodes in ib_pack.h Add common OPA header definitions for driver build: - opa_port_info.h - opa_smi.h - hfi1_user.h Additionally, ib_mad.h, has additional definitions that are common to ib_drivers including: - trap support - cca support The qib driver has the duplication removed in favor those in ib_mad.h Reviewed-by: Mike Marciniszyn Reviewed-by: John, Jubin Signed-off-by: Ira Weiny Signed-off-by: Dennis Dalessandro Signed-off-by: Doug Ledford

IB/core: Ethernet L2 attributes in verbs/cm structures

2014-01-14T22:20:54+00:00

This patch add the support for Ethernet L2 attributes in the verbs/cm/cma structures. When dealing with L2 Ethernet, we should use smac, dmac, vlan ID and priority in a similar manner that the IB L2 (and the L4 PKEY) attributes are used. Thus, those attributes were added to the following structures: * ib_ah_attr - added dmac * ib_qp_attr - added smac and vlan_id, (sl remains vlan priority) * ib_wc - added smac, vlan_id * ib_sa_path_rec - added smac, dmac, vlan_id * cm_av - added smac and vlan_id For the path record structure, extra care was taken to avoid the new fields when packing it into wire format, so we don't break the IB CM and SA wire protocol. On the active side, the CM fills. its internal structures from the path provided by the ULP. We add there taking the ETH L2 attributes and placing them into the CM Address Handle (struct cm_av). On the passive side, the CM fills its internal structures from the WC associated with the REQ message. We add there taking the ETH L2 attributes from the WC. When the HW driver provides the required ETH L2 attributes in the WC, they set the IB_WC_WITH_SMAC and IB_WC_WITH_VLAN flags. The IB core code checks for the presence of these flags, and in their absence does address resolution from the ib_init_ah_from_wc() helper function. ib_modify_qp_is_ok is also updated to consider the link layer. Some parameters are mandatory for Ethernet link layer, while they are irrelevant for IB. Vendor drivers are modified to support the new function signature.

IB/core: Add VLAN support for IBoE

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

Add 802.1q VLAN support to IBoE. The VLAN tag is encoded within the GID derived from a link local address in the following way: GID[11] GID[12] contain the VLAN ID when the GID contains a VLAN. The 3 bits user priority field of the packets are identical to the 3 bits of the SL. In case of rdma_cm apps, the TOS field is used to generate the SL field by doing a shift right of 5 bits effectively taking to 3 MS bits of the TOS field.

IB/core: Fix and clean up ib_ud_header_init()

2010-02-24T22:54:10+00:00

ib_ud_header_init() first clears header and then fills up the various fields. Later on, it tests header->immediate_present, which it has already cleared, so the condition is always false. Fix this by adding an immediate_present parameter and setting header->immediate_present as is done with grh_present. Also remove unused calculation of header_len.

[PATCH] IB: move include files to include/rdma

2005-08-27T03:37:38+00:00

Move the InfiniBand headers from drivers/infiniband/include to include/rdma. This allows InfiniBand-using code to live elsewhere, and lets us remove the ugly EXTRA_CFLAGS include path from the InfiniBand Makefiles. Signed-off-by: Roland Dreier
