Switches that care about QoS might have hardware support for reserving buffer pools for individual ports or traffic classes, and configuring their sizes and thresholds. Through devlink-sb (shared buffers), this is all configurable, as well as their occupancy being viewable. Add the plumbing in DSA for these operations. Individual drivers still need to call devlink_sb_register() with the shared buffers they want to expose. A helper was not created in DSA for this purpose (unlike, say, dsa_devlink_params_register), since in my opinion it does not bring any benefit over plainly calling devlink_sb_register() directly.
