GPRS: Support MS Radio Access Capability up to 255 bytes
TS 23.060 version 9.7.0 Release 9 section 6.14.1.1 states:
To allow for the addition of future radio technologies, frequency
bands, and other enhancements, the SGSN shall store the MS radio
access capability even if it is larger than specified in TS 24.008
[13], up to a maximum size of 255 octets.
Thanks to Jonathan Santos <jrsantos@jonathanrsantos.com> for spotting
this.
