2019-12-10bnxt_en: Add missing devlink health reporters for VFs.Vasundhara Volam
The VF driver also needs to create the health reporters since VFs are also involved in firmware reset and recovery. Modify bnxt_dl_register() and bnxt_dl_unregister() so that they can be called by the VFs to register/unregister devlink. Only the PF will register the devlink parameters. With devlink registered, we can now create the health reporters on the VFs.

Fix the logic to properly check the fw capabilities and create the devlink health reporters only when needed. The current code creates the reporters unconditionally as long as bp->fw_health is valid, and that's not correct. Call bnxt_dl_fw_reporters_create() directly from the init and reset code path instead of from bnxt_dl_register(). This allows the reporters to be adjusted when capabilities change. The same applies to bnxt_dl_fw_reporters_destroy().

2019-02-08devlink: publish params only after driver init is doneJiri Pirko
Currently, user can do dump or get of param values right after the devlink params are registered. However the driver may not be initialized which is an issue. The same problem happens during notification upon param registration. Allow driver to publish devlink params whenever it is ready to handle get() ops. Note that this cannot be resolved by init reordering, as the "driverinit" params have to be available before the driver is initialized (it needs the param values there).

2017-10-28bnxt_en: add support for Flower based vxlan encap/decap offloadSathya Perla
This patch adds IPv4 vxlan encap/decap action support to TC-flower offload. For vxlan encap, the driver maintains a tunnel encap hash-table. When a new flow with a tunnel encap action arrives, this table is looked up; if an encap entry exists, it uses the already programmed encap_record_handle as the tunnel_handle in the hwrm_cfa_flow_alloc cmd. Else, a new encap node is added and the L2 header fields are queried via a route lookup. hwrm_cfa_encap_record_alloc cmd is used to create a new encap record and the encap_record_handle is used as the tunnel_handle while adding the flow. For vxlan decap, the driver maintains a tunnel decap hash-table. When a new flow with a tunnel decap action arrives, this table is looked up; if a decap entry exists, it uses the already programmed decap_filter_handle as the tunnel_handle in the hwrm_cfa_flow_alloc cmd. Else, a new decap node is added and a decap_filter_handle is alloc'd via the hwrm_cfa_decap_filter_alloc cmd. This handle is used as the tunnel_handle while adding the flow. The code to issue the HWRM FW cmds is introduced in a follow-up patch.
