Based on Jes Sorensen work to make eswitch_offloads optional at compilation time, here is an initial RFC series that provides similar behavior, but here we do more accurate zoom in into eswitch and we break it into two HW components (MPFS & ESWITCH) to not break any functionality, and provide more modular separation.
In this series we provide the following modular separation and give the option of compiling out: MLX5_MPFS: Multi-Physical Function Switch (MPFs) needed only for Multi-PF configurations MLX5_ESWITCH: SRIOV Ethernet Switch With this separation, E-Switch becomes responsible only for ethernet SRIOV and needed only when SRIOV in enabled, otherwise it is not required. The two patches at the beginning are for preparation and cleanup only. Thanks, Saeed.
