Hello This patch 1. can handle LTE RRC messages and call respective dissectors 2. can handle LTE MAC frames, fill in the struct mac_lte_info and then call the mac-lte dissector. Following the GSMTAP header, there is a 15 byte mac_info which is needed to fill the struct mac_lte_info. The size mac_info need not necessarily be 15 byte. But these 15 bytes are necessary for the lte-mac dissector to understand the frame. 15 byte header is used by the LTE_FDD_EnodeB application from the openLTE project. There is also a patch for gsmtap.h. Please let me know your comments. Cheers Altaf
