Change in osmo-e1d[master]: Allow configuration of interfaces/lines via VTY

by laforge

Attention is currently required from: pespin. Hello Jenkins Builder, tnt, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-e1d/+/27016 to look at the new patch set (#6). Change subject: Allow configuration of interfaces/lines via VTY ...................................................................... Allow configuration of interfaces/lines via VTY So far, osmo-e1d automatically opened all compatible icE1usb devices and all E1 lines on those interfaces. Let's allow for 'interface' and 'line' configuration in the VTY. USB devices can be identified by their serial number string. If a given device (== E1 interface) has a VTY configuration, then only those E1 lines with VTY configuration opened. For each Line (icE1usb or vpair), the mode (channelized/superchannel) can also be set via VTY.

Change in osmo-iuh[master]: ranap_common_cn: add functions for direct access to decoder

by laforge

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-iuh/+/27002 ) Change subject: ranap_common_cn: add functions for direct access to decoder ...................................................................... ranap_common_cn: add functions for direct access to decoder The message encoder functions that decode a message to a struct ranap_message are only accessible via a callback function that is passed to ranap_cn_rx_cx The decoded ranap_message only lives inside the callback since it is freed by ranap_cn_rx_cx when the callback is done. In some situations this might make using the decoder incredibly difficult since it is not possible to keep the decoding results for an extended amount of time. Lets put the decoding into a separate function and use this function in ranap_cn_rx_cx. Then lets make the decoder and the free function public so that the decoder can be used in a more open way.
