  * Convert RFC 3390 larger initial window into an equivalent number of packets.

- * John Heffner states:
- *
- *      The RFC specifies a window of no more than 4380 bytes
- *      unless 2*MSS > 4380.  Reading the pseudocode in the RFC
- *      is a bit misleading because they use a clamp at 4380 bytes
- *      rather than a multiplier in the relevant range.
+ * This is based on the numbers specified in RFC 5681, 3.1.
