- * To account for possible PFC we should only subtract 1
- * byte whereas in mppe_compress() we added 2 bytes (+MPPE_OVHD);
- * However, we assume no PFC, thus subtracting 2 bytes.
+ * Note that for our test we only subtract 1 byte whereas in
+ * mppe_compress() we added 2 bytes (+MPPE_OVHD);
+ * this is to account for possible PFC.
