Set the field to allow posting multi packet send WQEs if hardware supports this feature. This doesn't mean the send WQEs will be for multi packet unless the send WQE was prepared according to multi packet send WQE format. User space shall use flag MLX5_IB_ALLOW_MPW to check if hardware supports MPW and allows MPW in SQ context. Signed-off-by:

Set underlay QPN as part of flow rule when it's applicable. There is one root flow table in the NIC RX namespace and all the underlay QPs steer the traffic to this flow table. In order to prevent QP to get traffic which is not target to its underlay QP, we need to set the underlay QP number as part of the steering matching. Note: When multicast traffic is sent the QPN filtering is done by the firmware as some early step. Adding the QPN match on the flow table entry is wrong as by that time the target QPN holds the multicast address (e.g. FF(s)) and it won't match. Signed-off-by:

mlx5 compatible devices have two ways of populating the MTT table of an MKEY: using a FW command and using a UMR WQE. A UMR is much faster, so it should be used whenever possible. Unfortunately the code today uses UMR only if the MKEY was allocated from the MR cache. Fix the code to use UMR even for MKEYs that were allocated using a FW command. Signed-off-by:

This patch is the first step in decoupling UMR usage and allocation from the MR cache. The only functional change in this patch is to enables UMR for MRs created with reg_create. This change fixes a bug where ODP memory regions that were not allocated from the MR cache did not have UMR enabled. Signed-off-by:

Software parsing (SWP) is a feature that can be used to instruct the device to stop using its internal parser and to parse packets on the transmit path according to offsets set for each packets. Through this feature, the device allows the handling of checksum and LSO by the hardware according to the location of IP and TCP/UDP headers. Enable SW parsing on Raw Ethernet send queue by default if firmware supports it and report these capabilities to user space. Signed-off-by:

IB CM calls ib_modify_port() irrespective of link layer. If the failure is returned, the mad agent gets unregistered for those devices. Recently, modify_port() hook was removed from some of the low level drivers as it was always returning success. This breaks rdma connection establishment over those devices. For ethernet devices, Qkey violation and port capabilities are not applicable. So returning success for RoCE when modify_port hook is is not implemented.
