+ * The internet does not really support MTUs greater than 1500, so most TCP traffic will

+ * The chance our traffic isn't IP at all is basically zero, so the IP overhead correction

+ *
+ * Furthermore, the likelyhood that we're having to deal with GSO (ie. > MTU) packets that
+ * are not IP/TCP is pretty small (few other things are supported by Linux) and worse case
+ * our extra overhead will be slightly off, but probably still better than assuming none.
+ *
+ * Most servers are also Linux and thus support/default to using TCP timestamp option
+ * (and indeed TCP timestamp option comes from RFC 1323 titled "TCP Extensions for High
+ * Performance" which also defined TCP window scaling and are thus absolutely ancient...).
+ *
+ * All together this should be more correct than if we simply ignored GSO frames
+ * (ie. counted them as single packets with no extra overhead)
+ *
+ * Especially since the number of packets is important for any future clat offload correction.

- *     are constant for all addresses in the prefix.
