+ * If you want to have use the full/normal API, check iwlist.c...
+ *
+ * Precaution when using scanning :
+ * The scanning operation disable normal network traffic, and therefore
+ * you should not abuse of scan.
+ * The scan need to check the presence of network on other frequencies.
+ * While you are checking those other frequencies, you can *NOT* be on
+ * your normal frequency to listen to normal traffic in the cell.
+ * You need typically in the order of one second to actively probe all
+ * 802.11b channels (do the maths). Some cards may do that in background,
+ * to reply to scan commands faster, but they still have to do it.
+ * Leaving the cell for such an extended period of time is pretty bad.
+ * Any kind of streaming/low latency traffic will be impacted, and the
+ * user will perceive it (easily checked with telnet). People trying to
+ * send traffic to you will retry packets and waste bandwidth. Some
+ * applications may be sensitive to those packet losses in weird ways,
+ * and tracing those weird behavior back to scanning may take time.
+ * If you are in ad-hoc mode, if two nodes scan approx at the same
+ * time, they won't see each other, which may create associations issues.
