Since the branch (tc >= pkt_len) == TRUE always returns, I suggest we remove the following "else", as it is redundant:
/* Color logic */
if (tc >= pkt_len) {
m->tc = tc - pkt_len;
m->te = te;
return e_RTE_METER_GREEN;
}

m->te = te - pkt_len;

I suggest we follow the logic from the diagram in the RFC rather than the logic in the text preceding the diagram. Although the two descriptions are equivalent (after a bit of thinking), the diagram seems more optimal to me:
/* Color logic */
if ((pkt_color == e_RTE_METER_GREEN) && (tc >= pkt_len)) {
m->tc = tc - pkt_len;
m->te = te;
return e_RTE_METER_GREEN;
}
if ((pkt_color != e_RTE_METER_RED) && (te >= pkt_len)) {
m->tc = tc;
m->te = te - pkt_len;
return e_RTE_METER_YELLOW;
}
/* If we end up here the color is RED */
m->tc = tc;
m->te = te;
return e_RTE_METER_RED;
