commit 5eae19098ac6e0563d3e176818ca6a6a4fb8656a

    trxcon/scheduler: transmit dummy frames on CBTX lchans
    If at the moment of transmission there are no frames in TX buffer,
    then either a dummy LAPDm frame (0x01, 0x03, 0x01, 0x2b ...) or a
    silence frame (depending on a codec in use) shall be transmitted.
    This is required for proper measurements on the BTS side.

commit 4cf722364bdafd90d12984531e4ec8c8548d6579

    trxcon/scheduler: introduce a new CBTX lchan flag
    This new flag is intended to indicate that continuous burst
    transmission is assumed on particular logical channel. In other
    words, if a logical channel has this flag, but there is nothing
    to transmit in a TX buffer, then either a dummy LAPDm frame or
    a silence frame shall be sent.
