Re: Request for DLT for new BlueZ Monitor

I'd like to suggest that "struct _pcap_bluetooth_monitor_
header" is too generic a name when this header only applies to the
internal workings of an operating system's HCI and adapter-lifetime
traffic.

Ok, "struct _pcap_bluetooth_linux_monitor_header" is ok?
But this is for second phase. There is need to have new DLT first.

By the way:
According to [1] "supplements DLT_BLUETOOTH_LE_LL which already exists
but is not used" - is it truth? Wireshark already use it in "btle"
dissector.

There are other forms of bluetooth monitoring that are not OS-specific nor even cover HCI.  For example open-source 
sniffers like ubertooth and gr-bluetooth capture at the RF level.  It's likely that a DLT allocation request will be 
forthcoming for capturing bluetooth over-the-air [1].
