Dynamic Spectrum Management is a precondition for G.993.5 (VDSL2 vectoring).
Signed-off-by: Mathias Kresin <open...@kresin.me> --- It has been sucessfully tested by a user with a german 1&1 VDSL2 vectoring line, who could only get the ADSL2+ fallback speed[1] without this patch (regardless of vectoring support in firmware). Vectoring requires a firmware with vectoring support, otherwise the line is limited to the ADSL2+ fallback speed. The user reported that he could only get stable connections with firmware versions 7.3.3+[2]. It has been tested by my self with a "normal" VDSL2 line.
