New prim PH_DATA_E_IND. - all E-ch frames are indicated by recv_Echannel(), which pushes E-Channel frames into dch's rqueue - if dchannel is opened with channel nr 0, no E-Channel logging is requested - if dchannel is opened with channel nr 1, E-Channel logging is requested. if layer1 does not support that, -EINVAL in return is appropriate Signed-off-by: Martin Bachem <m.bachem@gmx.de> Signed-off-by: Karsten Keil <kkeil@suse.de>
