Hopefully, this means that the file's LINKTYPE_ value would be LINKTYPE_BLUETOOTH_LE_LL, not LINKTYPE_PPI.

which includes the DLT (thank you for assigning!)

Oh, dear, it sounds as if the file's LINKTYPE_ value would be LINKTYPE_PPI.

So what is a program to do if handed a file with a LINKTYPE_ value of LINKTYPE_BLUETOOTH_LE_LL?

I *REALLY* don't want to see *ANY* LINKTYPE_/DLT_ values assigned that can *ONLY* be used in a LINKTYPE_PPI file.

Could you please switch to a scheme where the state information is a pseudo-header that precedes the payload in the 
packet data?  We could assign a LINKTYPE_BLUETOOTH_LE_LL_UBERTOOTH value for that.
