+ * Linux-IrDA packets. Protocol defined at http://www.irda.org.
+ * Those packets include IrLAP headers and above (IrLMP...), but
+ * don't include Phy framing (SOF/EOF/CRC & byte stuffing), because Phy
+ * framing can be handled by the hardware and depend on the bitrate.
+ * This is exactly the format you would get capturing on a Linux-IrDA
+ * interface (irdaX), but not on a raw serial port.
+ * Note the capture is done in "Linux-cooked" mode, so each packet include
+ * a fake packet header (struct sll_header). This is because IrDA packet
+ * decoding is dependant on the direction of the packet (incomming or
+ * outgoing).
+ * When/if other platform implement IrDA capture, we may revisit the
+ * issue and define a real DLT_IRDA...
