[PATCH rdma-next v1 07/12] IB/opa-vnic: VNIC MAC table support

OPA VNIC MAC table contains the MAC address to DLID mappings provided by the Ethernet manager. During transmission, the MAC table provides the MAC address to DLID translation. Implement MAC table using simple hash list. Also provide support to update/query the MAC table by Ethernet manager.

[PATCH rdma-next v1 09/12] IB/opa-vnic: VNIC Ethernet Management Agent (VEMA) function

OPA VEMA function interfaces with the Infiniband MAD stack to exchange the management information packets with the Ethernet Manager (EM). It interfaces with the OPA VNIC netdev function to SET/GET the management information. The information exchanged with the EM includes class port details,

[PATCH rdma-next v1 11/12] IB/hfi1: Virtual Network Interface Controller (VNIC) HW support

HFI1 HW specific support for VNIC functionality. Dynamically allocate a set of contexts for VNIC when the first vnic port is instantiated. Allocate VNIC contexts from user contexts pool and return them back to the same pool while freeing up. Set aside enough MSI-X interrupts for VNIC contexts and

[PATCH rdma-next v1 06/12] IB/opa-vnic: VNIC statistics support
