net/mlx5: Ethernet resource handling files
This patch contains the resource handling files: - flow_table.c: This file contains the code to handle the low level API to configure hardware flow table. It is separated from the flow_table_en.c, because it will be used in the future by Raw Ethernet QP in mlx5_ib too. - en_flow_table.[ch]: Ethernet flow steering handling. The flow table object contain a mapping between flow specs and TIRs. This mechanism will be used also to configure e-switch in the future, when SR-IOV support will be added. - transobj.[ch] - Low level functions to create/modify/destroy the transport objects: RQ/SQ/TIR/TIS - vport.[ch] - Handle attributes of a virtual port (vPort) in the embedded switch. Currently this switch is a passthrough, until SR-IOV support will be added. Signed-off-by: Amir Vadai <amirv@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
