This patch fixes the wrong scale of the Bits graph in the DSL Status page AND checks the correct range (in Annex A mode: [0-31] for normal ADSL; [0-63] for Annex M).
TODO added at the begining for checking Annex B mode, if someone knows how to do! ('nvram get dsl_annex' not set in pure Annex_A mode)
Moreover, the 'adslctl2' command has bugs. In Annex M, the tool reports "0" for bins [32-59] . Other firmwares reports correct values. Someone can fix it, please?
