> Is there any easy way to analyze Um GPRS/RLC, encapsulated in GSMTAP at the L1/L2 boundary, in Wireshark?  I tried just putting the frames coming into L1 into GSMTAP packets, but Wireshark tries to analyze them as LAPDm.  There was nothing obvious in the GSMTAP_TYPE_* values to correspond to Um GPRS/RLC, though I admit that I have not tried other values yet.

type = GSMTAP_TYPE_UM
sub_type = GSMTAP_CHANNEL_PACCH

Cheers,
