In the flowtables offload all the devices in the flowtables share the same flow_block. An offload rule will be installed on all the devices. This scenario is not correct. It is no problem if there are only two devices in the flowtable, The rule with ingress and egress on the same device can be reject by driver. But more than two devices in the flowtable will install the wrong rules on hardware. For example: Three devices in a offload flowtables: dev_a, dev_b, dev_c A rule ingress from dev_a and egress to dev_b: The rule will install on device dev_a. The rule will try to install on dev_b but failed for ingress and egress on the same device. The rule will install on dev_c. This is not correct. The flowtables offload avoid this case through restricting the ingress dev with FLOW_DISSECTOR_KEY_META. So the mlx5e driver also should support the FLOW_DISSECTOR_KEY_META parse. Signed-off-by:

Leon Romanovsky says: ==================== Use ODP MRs for kernel ULPs The following series extends MR creation routines to allow creation of user MRs through kernel ULPs as a proxy. The immediate use case is to allow RDS to work over FS-DAX, which requires ODP (on-demand-paging) MRs to be created and such MRs were not possible to create prior this series. The first part of this patchset extends RDMA to have special verb ib_reg_user_mr(). The common use case that uses this function is a userspace application that allocates memory for HCA access but the responsibility to register the memory at the HCA is on an kernel ULP. This ULP acts as an agent for the userspace application. The second part provides advise MR functionality for ULPs. This is integral part of ODP flows and used to trigger pagefaults in advance to prepare memory before running working set. The third part is actual user of those in-kernel APIs. ==================== Signed-off-by:
