maybe wrong GTPIE_RAB_CONTEXT fixed length?

[areadev]

I was looking inside gtp/gtpie.c and I found at line 280
that the length of a rab context ie is 7, but inside
the 29.060 specs it looks like that it should be 9,
so there should be "p += 1 + 9;" am I missing something?

case GTPIE_RAB_CONTEXT: /* TV GTPIE types with value length 7 /
if (j<GTPIE_SIZE) {
ie[j] = (union gtpie_member) p;
if (GTPIE_DEBUG) printf("GTPIE TV 7 found. Type %d\n", ie[j]->tv0.t);
p+= 1 + 7;
j++;
}
