What I did

Updated the Mellanox generate_dump SDK-sysfs collection to skip sysfs nodes that are accessible only in FW control when the module is in SW control.

How I did it

Updated the Mellanox generate_dump SDK-sysfs collection to skip sysfs nodes that are accessible only in FW control when the module is in SW control.

How to verify it

Enable SW control mode and run show techsupport. In the generated dump, verify that module_ext_info, els_laser_status, els_error and module_cpo_info are absent from the SW-control modules' sysfs directory, and that no related errors appear in the log.
