  • ef7f28cc7f Merge branch 'jolly_new' Merge is based on jolly_new branch with two modifications. 1. Modified PCU L1 interface. pcu_l1_if.cpp - common functions for tx and rx messages on L1 interface. sysmo_sock.cpp - SYSMO-PCU socket functions. openbts_sock.cpp - OpenBTS-PCU socket functions. pcuif_proto.h - L1 interface's primitives. 2. Modified encoding of RLC/MAC Control messages, now we use structures and encode_gsm_rlcmac_downlink() function for encode control blocks (without hand-coding).
