fwctl/bnxt_en: Refactor aux bus functions to be more generic 2026-03-27T12:12:36+00:00 Pavan Chebbi pavan.chebbi@broadcom.com 2026-03-14T15:16:02+00:00 2c7c85c8c7881d57c5fa1114f4b0dbd7fc53a36f Up until now there was only one auxiliary device that bnxt created and that was for RoCE driver. bnxt fwctl is also going to use an aux bus device that bnxt should create. This requires some nomenclature changes and refactoring of the existing bnxt aux dev functions. Convert 'aux_priv' and 'edev' members of struct bnxt into arrays where each element contains supported auxbus device's data. Move struct bnxt_aux_priv from bnxt.h to ulp.h because that is where it belongs. Make aux bus init/uninit/add/del functions more generic which will loop through all the aux device types. Make bnxt_ulp_start/stop functions (the only other common functions applicable to any aux device) loop through the aux devices to update their config and states. Make callers of bnxt_ulp_start() call it only when there are no errors. Also, as an improvement in code, bnxt_register_dev() can skip unnecessary dereferencing of edev from bp, instead use the edev pointer from the function parameter. Future patches will reuse these functions to add an aux bus device for fwctl.
