Descriptors that came from coalesced frames will now carry usage info.
In order to prevent overcoutning, only the first segment from each frame
will report this information; the rest will report 0.
This allows a simple calculation of summing the coal_bytes and coal_bufsize
values reported and dividing to determine the total ratio over a given
period.
These values will be reported in the SKB via a new Control Block struct,
accessable via RMNET_SKB_CB(skb);
