PS1, Line 235: /* 3GPP TS 44.018, table 9.1.8.1, note 2b: Request Reference shall be set to 127

Feel free to check out the spec. reference mentioned in the comment. TL;DR In case of 11 bit Access Burst, the actual RA is contained in IA Rest Octets (grep 'ext_ra' fiels), while this field is set to 127. So please keep it - it's here for purpose.
